To translate analogue audio tape logs correctly, preserve the carrier identifier, recording speed, track arrangement, channel assignment, physical condition, transfer settings and every uncertainty recorded by the archivist. Reel-to-reel audio and cassette documentation often looks like a short equipment checklist, yet a single misplaced fraction or ambiguous use of “side” can make a preservation copy impossible to trace back to the source recording.
This guide explains how to translate reel-to-reel tape labels, magnetic tape inspection records, audio digitisation metadata, playback-speed notations, stereo and mono track descriptions, preservation-file settings and archival transfer logs. It is intended for translators, librarians, sound archivists, oral-history teams, cataloguers and students who need precise English explanations of audio preservation vocabulary.
The practical answer is to treat an audio transfer record as evidence of what was examined and done—not as a promise that the recording has been repaired, identified or fully heard. Translate the human-readable description, preserve stable identifiers and measurement units, check the equipment and file metadata against the source, and explicitly retain phrases such as “not verified,” “reported,” “presumed” and “transfer unsuccessful.”
Definition: what a correct audio-preservation translation preserves
Correct translation of an analogue audio transfer log means carrying the source record’s operational meaning into another language while leaving its identities, physical specifications, actions and confidence level intact. It is not audio restoration, archive authentication, transcription of speech or a substitute for preservation expertise. When a term has no tidy everyday equivalent, a brief gloss is safer than a false familiar synonym.
A sound archive normally needs at least three kinds of description: descriptive metadata about the programme or collection, technical metadata about carriers and signal transfer, and administrative metadata such as rights, custody, fixity checks and transfer responsibility. These layers interact, but each makes a different kind of claim. A translator needs to understand which layer a sentence belongs to before changing its wording.
The visible problem: a short phrase can break an entire retrieval chain
Imagine a researcher asking for the original source of a digitised speech. The catalogue identifies a box, the box contains two reels, one reel has an uncertain date, and the transfer sheet records only one side as completed. If the translation merges reel and box IDs, resolves the date by intuition and describes the whole programme as digitised, the reader receives a smooth account that cannot be trusted. The remedy is careful separation rather than literary elegance.
Before writing, ask five questions: What physical object does this entry describe? Is the statement observed, measured, copied from a label or supplied by another person? Which numerical values have associated units? Was anything actually done to the tape, and what was its outcome? What restrictions govern access? These questions identify the technical meaning that must survive.
First principles: understand the evidence before translating it
1. A carrier is not the sound file
The physical reel, compact cassette, digital transfer master and listening copy are four different objects. A title can belong to a collection while a shelf mark belongs to one reel. A translator must not give the preservation file the original carrier’s identity without connecting the two through the archive’s identifiers.
A useful verification exercise is to locate the specific source field that supports this statement, then ask what would become false if the label were broadened. In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
2. Speed is a controlled technical field
Tape speed may be expressed as inches per second, centimetres per second or shorthand such as 7½ ips. Those are not durations, sampling rates or file bitrates. Preserve the value and unit, and distinguish recorded speed from playback speed used during an attempted transfer.
A useful verification exercise is to locate the specific source field that supports this statement, then ask what would become false if the label were broadened. In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
3. Track format is a physical layout
Full-track mono, half-track stereo and quarter-track arrangements are not interchangeable synonyms for single-channel, stereo or multichannel digital files. The physical placement of recorded tracks controls what a replay head can recover. Translate only the configuration documented by the specialist.

In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
4. Channels are not speakers
A channel assignment such as left = interviewer, right = respondent describes the captured audio channels. It does not necessarily identify two microphones, two people or a true stereo sound field. Archive descriptions often include hypotheses that must remain hypotheses.

In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
5. Condition is observation, not diagnosis
Terms such as sticky deposit, edge damage, creasing, mould suspected, oxide shedding or dropout can be observational findings. Translators must not silently turn observations into diagnoses, treatment instructions or assurances of playability.

In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
6. Transfer is a documented event
A successful transfer, a partial transfer, an inspection-only encounter and a failed transfer are different statuses. A digitisation log needs a date, operator, machine or workflow identifier and result. Render the status verbs faithfully instead of smoothing them into generic “digitised.”

In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
7. Equalisation labels carry provenance
A note such as NAB or CCIR/IEC may identify a replay equalisation curve, but conventions vary with tape, period and equipment. Preserve the historical label and add an explanatory gloss where appropriate rather than pretending one universal setting fits every reel.
A useful verification exercise is to locate the specific source field that supports this statement, then ask what would become false if the label were broadened. In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
8. A master and an access copy have different jobs
An uncompressed preservation master, a derived web listening file and a transcript can all represent the same programme without being the same technical object. Do not translate “access derivative created” as “master repaired” or replace the original checksum with a derivative’s checksum.

In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
9. Sample rate differs from bit depth
A transfer written 96 kHz / 24 bit specifies two independent digital audio properties. kHz is not kb/s, and bit depth does not establish the file’s duration or number of channels. Keep labels beside values during localisation.
A useful verification exercise is to locate the specific source field that supports this statement, then ask what would become false if the label were broadened. In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
10. Clock time is not elapsed duration
The handwritten 14:25 might be a time of day, timecode, elapsed counter or entry number. Only the record’s column heading and accompanying description establish which it is. Never convert the value to a programme duration without evidence.
A useful verification exercise is to locate the specific source field that supports this statement, then ask what would become false if the label were broadened. In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
11. Rights and access live beside preservation
A recording may be technically transferred but restricted for ethical, contractual or donor-agreement reasons. Translation should not convert “preservation only” into “public listening available” or imply that an unknown rights holder has authorised online publication.
A useful verification exercise is to locate the specific source field that supports this statement, then ask what would become false if the label were broadened. In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
12. Absence is not a negative finding
A blank field does not prove a tape has no label, no sound or no damage. The source may never have been inspected. Record ‘not recorded’ or ‘not examined’ when that is what the form actually conveys, not categorical ‘none’.

In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
13. Object-level identifiers must remain stable
Shelf marks, accession numbers, reel numbers and transfer-job IDs establish a chain from material to file. Do not translate or normalise such identifiers as ordinary words; a reader must be able to request the same physical object after reading another-language record.

In a sound archive, precision is not pedantry: the same short entry may be reused for collection description, equipment troubleshooting, digitisation reporting and public discovery. Keep the original source and a translation note available when a field’s meaning remains unresolved.
14. The evidence chain must be reviewable
Another archivist should be able to reconstruct what the translator learned, what was left uncertain and which technical fields were copied verbatim. That requires a versioned source image or transcription and a target note that can be reconciled field by field.

A repeatable twelve-stage method for audio tape log translation
Stage 1: Identify the record type
Check whether the document is a container label, accession catalogue, inspection form, replay log, audio-file metadata sheet or public-facing description. The same label can be meaningful in different ways in each document. Record the intended audience before deciding whether to use specialist jargon or a short explanatory gloss.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Stage 2: Freeze the immutable identifiers
Copy accession numbers, reel references, file IDs, checksum values and stable shelf marks before writing normal prose. Put each in its own field and preserve punctuation and leading zeroes. If an unclear digit appears on the label, show uncertainty instead of guessing from a neighbouring accession.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Stage 3: Separate physical and digital properties
Mark which fields describe the tape and which describe the digitised file. “¼-inch, 7½ ips” belongs to the source carrier; “96 kHz, 24-bit WAV” belongs to a transfer. The reader should not be forced to infer this distinction from a translated sentence.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Stage 4: Expand ambiguous abbreviations cautiously
Create a local abbreviation list, but only expand a term when the source’s institution, equipment documentation or adjacent columns support that expansion. A presumed reel orientation or abbreviated defect note may need an uncertainty marker rather than a polished invented explanation.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Stage 5: Preserve reported versus observed facts
Sort wording into observed, reported by donor, inferred by cataloguer and measured during transfer. Use verbs such as “label states,” “reported,” “observed” and “measured” deliberately. A translation that erases this difference changes the archive’s evidential claim.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Stage 6: Check speed, width and duration independently
Read units alongside each number. Convert 7½ ips to 19.05 cm/s only if conversion serves the reader and is exact for the cited speed; otherwise retain the source. Duration must be copied from a duration field, not computed from reel diameter or assumed from speed alone.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Stage 7: Verify the track map
If the source provides a drawing of tape tracks or a channel map, ask whether forward and reverse directions, stereo pairs and recorded sides have been distinguished. Preserve orientation markers and notes that certain tracks were not transferred.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Stage 8: Retain the transfer outcome
Keep unsuccessful, partial, completed and preservation-only outcomes distinct. Note any discontinuities, dropout, splices or transfer interruption as written. Resist the tempting summary “successfully restored” unless that is explicitly supported by an authoritative record.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Stage 9: Map format and processing choices
Verify sampling rate, bit depth, container and codec, channel count, file naming, sidecar metadata and checksums. A WAV file may be uncompressed but its existence does not prove that equalisation or mechanical replay was correct; separate the claim being translated from the claim being audited.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Stage 10: Protect access and ethical restrictions
Keep embargoes, donor terms, consent status and copying permissions attached to the correct object or collection. If a log describes sensitive testimony, translate operational metadata without unnecessarily reproducing personal details in public learning examples.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Stage 11: Run a bilingual field-by-field proof
Compare source and target in matching rows: date, carrier, speed, tracking, condition, intervention, output, quality-control status, rights. Use a second pass focusing only on numbers, codes, qualifier words and untranslatable identifiers.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Stage 12: Test retrieval and future interpretation
Ask a colleague who has not seen the source whether the translation identifies the same reel, indicates what was actually transferred and leaves every unresolved point unresolved. If they cannot reconstruct the provenance chain, revise the translation rather than adding speculative statements.
At this stage, produce a visible checkable result rather than relying on memory: a two-column field map, a copied identifier list, a unit check, a status comparison or a reviewer query. The purpose is to stop a small source ambiguity from spreading into file metadata, a public catalogue and later derivatives. Record unanswered questions; a transparent pending decision is preferable to an attractive but unsupported answer.
Twenty-four worked examples with translations and verification
The following excerpts are constructed teaching examples rather than quotations from a real collection. Their invented identifiers and dates demonstrate how to preserve evidence without implying that a particular archive holds these items. Each case identifies the phrase, an accurate English rendering, the common false interpretation and a practical check.
01. Label identity
Source excerpt: Reel R-014 / Box 03 / ‘lecture? 1968’ handwritten.
A careful English rendering would read: “Reel R-014, Box 03; handwritten possible title ‘lecture’; date ‘1968’ appears on label, unverified.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Recorded lecture, 1968, accurately identified” makes an uncertain label into an asserted programme title and date.
Audit the translation by applying this check: Compare image of box and reel separately; a question mark must remain attached to the donor’s wording. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
02. Fractions in tape speed
Source excerpt: 7 1/2 ips; playback test at 3 3/4 ips.
A careful English rendering would read: “Labelled recording speed: 7½ inches per second; trial playback: 3¾ inches per second.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. Combining these fields would suggest the tape was originally recorded at the lower playback-test speed.
Audit the translation by applying this check: Check two separate rows: labelled speed and test speed; do not infer that either was objectively verified. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
03. Source width
Source excerpt: 1/4-in tape, 7-in reel.
A careful English rendering would read: “Quarter-inch magnetic tape on a seven-inch reel.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. Calling this a quarter-inch digital audio track or a seven-inch sound file confuses physical media with data.
Audit the translation by applying this check: Verify physical width versus reel diameter; both are dimensions but describe different objects. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
04. Monophonic format
Source excerpt: full-track mono; one programme.
A careful English rendering would read: “Full-track monophonic recording; one documented programme.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. Changing it to “single-track stereo” invents a two-channel presentation not supported by the source.
Audit the translation by applying this check: Keep physical track arrangement and audio channel status in separate terms. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
05. Quarter-track ambiguity
Source excerpt: quarter-track; side B untested.
A careful English rendering would read: “Quarter-track format noted; reverse side not tested.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Four tracks were digitised” wrongly converts a physical layout designation into a completed operation.
Audit the translation by applying this check: Inspect transfer outcome field and any drawn track map before counting recovered tracks. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
06. Channel annotations
Source excerpt: L: chair / R: questions.
A careful English rendering would read: “Left channel labelled ‘chair’; right channel labelled ‘questions’.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Chairperson interviewed the audience in stereo” invents a narrative and perhaps a speaker identity.
Audit the translation by applying this check: Preserve channel labels; the collection may contain a meeting, not an interview. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
07. Date written on box
Source excerpt: 12/3/74; locale unknown.
A careful English rendering would read: “Date on box: 12/3/74 (day/month order not established).” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “12 March 1974” is unsafe when the source may use month/day order.
Audit the translation by applying this check: Verify date convention from collection records before choosing a calendrical rendering. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
08. Sticky deposit note
Source excerpt: brown tacky residue at hub; play deferred.
A careful English rendering would read: “Brown tacky residue observed near the hub; playback deferred.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Tape repaired and playable” reverses the decision to avoid replay.
Audit the translation by applying this check: Preserve observed condition and deferred status; refer treatment decisions to trained preservation specialists. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
09. Mould uncertainty
Source excerpt: suspected mould; isolate pending review.
A careful English rendering would read: “Possible mould reported; carrier isolated pending specialist review.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Mould removed” fabricates both diagnosis and a treatment step.
Audit the translation by applying this check: Separate suspicion, isolation and completion; do not introduce health or conservation instructions absent from the record. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
10. Treatment record
Source excerpt: heat treatment reportedly 2012; no receipt.
A careful English rendering would read: “Heat treatment reported in 2012; supporting treatment record not located.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Professionally baked and stabilised in 2012” upgrades hearsay into confirmed preservation evidence.
Audit the translation by applying this check: Keep the qualifier “reportedly” and the absence of documentation visible. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
11. Head alignment
Source excerpt: azimuth adjusted during transfer; settings retained.
A careful English rendering would read: “Replay-head azimuth adjusted during transfer; settings documented.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Recording was remastered” hides the technical action and falsely claims a production result.
Audit the translation by applying this check: Cross-reference equipment log and avoid treating playback adjustment as an edit to original content. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
12. Equalisation mark
Source excerpt: EQ: NAB? pencil entry.
A careful English rendering would read: “Equalisation noted as ‘NAB?’ in pencil; not confirmed.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. Removing the question mark implies a verified replay setting.
Audit the translation by applying this check: Preserve the source’s uncertainty and consult local equipment documentation before any explanatory expansion. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
13. Recording ends early
Source excerpt: end of audio 00:43:02; carrier continues.
A careful English rendering would read: “Audio ends at elapsed counter 00:43:02; tape continues beyond recorded content.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Tape duration: 43 minutes two seconds” incorrectly equates content endpoint with entire carrier length.
Audit the translation by applying this check: Check whether elapsed counter, duration and residual blank tape occupy separate columns. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
14. Unidentified opening tone
Source excerpt: tone present 00:00–00:08; source unknown.
A careful English rendering would read: “Tone audible at the beginning, approximately eight seconds; purpose unidentified.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Standard calibration tone” attributes a function never established by the listening note.
Audit the translation by applying this check: Retain auditory observation and avoid assigning a technical purpose without evidence. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
15. Dropout location
Source excerpt: brief loss at 12m14s.
A careful English rendering would read: “Brief audio dropout around elapsed 12:14.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Twelve minutes of sound missing” exaggerates a momentary defect into a long gap.
Audit the translation by applying this check: Keep the timestamp format and the distinction between defect occurrence and defect duration. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
16. Splice observation
Source excerpt: splice at 18:40, no content loss verified.
A careful English rendering would read: “Splice noted near 18:40; effect on recorded content not verified.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Complete programme preserved” claims completeness that has not been checked.
Audit the translation by applying this check: Treat physical join and content integrity as separate evidential questions. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
17. Recording date vs transfer date
Source excerpt: tape label 1979; transferred 2026-10-20.
A careful English rendering would read: “Carrier bears 1979 label; digital transfer recorded on 20 October 2026.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Recorded in 2026” misattributes the digitisation date to the original event.
Audit the translation by applying this check: Keep original-event chronology, carrier labels and workflow dates apart. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
18. Digital output parameters
Source excerpt: WAV PCM 96kHz 24bit 2ch.
A careful English rendering would read: “Uncompressed PCM WAV transfer, 96 kHz sampling rate, 24-bit depth, two channels.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “96 kbps MP3” changes both the unit and the file format.
Audit the translation by applying this check: Verify sample rate, depth, codec/container and channel count as four separate fields. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
19. Preservation derivative
Source excerpt: MASTER_004.wav; ACCESS_004.mp3.
A careful English rendering would read: “Preservation master: MASTER_004.wav; listening derivative: ACCESS_004.mp3.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. Calling the MP3 a master discards the distinction between preservation evidence and distribution copy.
Audit the translation by applying this check: Check the archive’s naming convention and do not infer equivalence from similar base names. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
20. Fixity record
Source excerpt: SHA-256 recorded for output master; not yet rechecked.
A careful English rendering would read: “SHA-256 checksum stored for preservation master; subsequent fixity check pending.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Integrity verified” claims a check that has not yet occurred.
Audit the translation by applying this check: Retain the algorithm name, exact value in the actual record and pending verification state. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
21. Access permission
Source excerpt: digitised, restricted until donor review.
A careful English rendering would read: “Digitisation completed; access restricted pending donor review.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Available online” confuses successful preservation processing with permission to distribute.
Audit the translation by applying this check: Verify rights/access status after checking file status; the two decisions are independent. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
22. Partial transfer
Source excerpt: side A transferred; side B no stable replay.
A careful English rendering would read: “Side A transferred; side B could not be played stably.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Both sides digitised” fills the operational gap with a false success.
Audit the translation by applying this check: Acknowledge partial coverage and preserve which side or track failed. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
23. Missing tape label
Source excerpt: container has no label; accession file gives possible title.
A careful English rendering would read: “Container unlabelled; possible title supplied by accession notes.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. “Title printed on cassette” assigns the wording to the wrong source.
Audit the translation by applying this check: Use separate evidence attribution: container observation versus catalogue inference. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
24. Replay machine metadata
Source excerpt: Machine M-03; alignment report AF-11; operator initials JT.
A careful English rendering would read: “Replay machine M-03; alignment record AF-11; operator recorded as JT.” The key is to preserve what the source actually records, including the kind of observation and any qualifier. Translating codes as names or replacing initials with an assumed individual compromises traceability.
Audit the translation by applying this check: Check identifiers verbatim and leave identities unresolved unless authorised staff metadata confirms them. Where another language uses a different technical term, a brief local gloss may explain the unfamiliar field, but it must not change the object, event, quantity, identity or status that the source documents.
Failure modes and how to repair them
Failure 1: Unit substitution
Converting ips into kHz or mixing sampling rate with bitrate can make the description unusable. Place the original symbol beside the technical term and ask which physical quantity it measures.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Failure 2: False completion
Words such as digitised, restored, stabilised, cleaned and catalogued represent different actions. A transfer log cannot support a claim about treatment or complete item description unless it explicitly says so.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Failure 3: Lost uncertainty
An illegible digit, pencilled question mark or donor-reported title is evidence about confidence. Removing uncertainty makes the translated record look more authoritative than its source.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Failure 4: Wrong provenance
A reel’s label, an archive’s accession sheet, an operator’s observation and a later cataloguer’s note have different authors. Keep those voices attributed.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Failure 5: Track/channel conflation
A physical quarter-track configuration is not identical to a four-channel file. Preserve track layout and digital channel count as independent fields.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Failure 6: Unwarranted date normalisation
Ambiguous numeric dates should not be resolved by guessing the translator’s national convention. Record uncertainty or seek collection-level evidence.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Failure 7: Condition-to-safety leap
“Possible mould” or “sticky residue” is not a preservation diagnosis, and this educational article is not a playback treatment manual. State the observation without giving dangerous unverified treatment instructions.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Failure 8: Rights loss
A preservation master can exist while listening access remains embargoed. Rights metadata must survive in the translation and link to the correct object.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Failure 9: Digital filename edits
Replacing underscores, zeroes or hash values to make them more readable can break file reconciliation. Use descriptive text around exact identifiers instead.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Failure 10: Incomplete side coverage
“Transferred” may refer only to one side, one channel or part of the programme. Keep the portion and unsuccessful attempts in the same sentence as the outcome.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Failure 11: Overexplained abbreviation
Technical shorthand sometimes varies by institution. A translator’s expansion is not evidence; mark uncertain expansions or retain the source token with a gloss.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Failure 12: Unsupported interpretation
A damaged tape may have two distinct programmes or one interrupted recording. Never infer content structure solely from a physical splice or a counter position.
Repair procedure: reopen the original source image or field export, mark the exact phrase responsible for the wrong claim, and revise only the affected translation unit. Then search the current draft for the same wording in captions, summaries, FAQs and linked descriptions. One corrected term does not help if an earlier incorrect statement remains elsewhere in the article or archive record.
Practice: from copied terms to defensible records
For each task, write a two-column source/target record and a short reviewer note. Then compare your version to the principles above. Successful practice means being able to explain why you have not supplied a missing fact, not merely producing fluent sentences.
Exercise 1: Two speeds
A log says 7½ ips on the reel and 3¾ ips on the playback form. Produce two separate sentences and explain why only one might describe the recording speed.
Self-check: underline every identity, measurement, permission, evidence qualifier and verb that indicates a completed or incomplete action. Explain which fields are safe to translate and which should remain exact tokens. If the task depends on unknown equipment, rights or collection practice, write a focused question for the responsible archivist rather than choosing a convenient assumption.
Exercise 2: Unconfirmed track layout
Translate “2 trk? mono / side 2 blank?” without asserting a stereo recording or silence. Keep each question mark in a form a future technician can audit.
Self-check: underline every identity, measurement, permission, evidence qualifier and verb that indicates a completed or incomplete action. Explain which fields are safe to translate and which should remain exact tokens. If the task depends on unknown equipment, rights or collection practice, write a focused question for the responsible archivist rather than choosing a convenient assumption.
Exercise 3: Conflicting date forms
A donor lists 04/05/72, a cataloguer adds “possibly May.” Prepare a neutral description that shows two pieces of evidence, rather than choosing a date.
Self-check: underline every identity, measurement, permission, evidence qualifier and verb that indicates a completed or incomplete action. Explain which fields are safe to translate and which should remain exact tokens. If the task depends on unknown equipment, rights or collection practice, write a focused question for the responsible archivist rather than choosing a convenient assumption.
Exercise 4: Rights versus availability
Write a bilingual summary of “transfer complete; public access pending consent.” The result must not suggest that permission has already been granted.
Self-check: underline every identity, measurement, permission, evidence qualifier and verb that indicates a completed or incomplete action. Explain which fields are safe to translate and which should remain exact tokens. If the task depends on unknown equipment, rights or collection practice, write a focused question for the responsible archivist rather than choosing a convenient assumption.
Exercise 5: Incomplete source
A reel’s box has a title but no performer information. Create a description with the title as box evidence and a separate “performer not identified” field.
Self-check: underline every identity, measurement, permission, evidence qualifier and verb that indicates a completed or incomplete action. Explain which fields are safe to translate and which should remain exact tokens. If the task depends on unknown equipment, rights or collection practice, write a focused question for the responsible archivist rather than choosing a convenient assumption.
Exercise 6: Transfer files
Explain the difference between `A003_master.wav` and `A003_preview.mp3`. Keep filenames unchanged, identify their jobs, and do not infer technical specs from extensions alone.
Self-check: underline every identity, measurement, permission, evidence qualifier and verb that indicates a completed or incomplete action. Explain which fields are safe to translate and which should remain exact tokens. If the task depends on unknown equipment, rights or collection practice, write a focused question for the responsible archivist rather than choosing a convenient assumption.
Exercise 7: Mechanical defect
Translate “brown deposit; no replay attempted.” The target must avoid declaring mould, recommending repair or implying that sound has been checked.
Self-check: underline every identity, measurement, permission, evidence qualifier and verb that indicates a completed or incomplete action. Explain which fields are safe to translate and which should remain exact tokens. If the task depends on unknown equipment, rights or collection practice, write a focused question for the responsible archivist rather than choosing a convenient assumption.
Exercise 8: Timing position
Interpret “dropout 14:03” when the source field is labelled “elapsed”. Show the meaning as an elapsed position, not a time of day.
Self-check: underline every identity, measurement, permission, evidence qualifier and verb that indicates a completed or incomplete action. Explain which fields are safe to translate and which should remain exact tokens. If the task depends on unknown equipment, rights or collection practice, write a focused question for the responsible archivist rather than choosing a convenient assumption.
Exercise 9: Checksum status
The checksum is present but no fixity recheck is logged. State exactly what is documented and what remains unverified.
Self-check: underline every identity, measurement, permission, evidence qualifier and verb that indicates a completed or incomplete action. Explain which fields are safe to translate and which should remain exact tokens. If the task depends on unknown equipment, rights or collection practice, write a focused question for the responsible archivist rather than choosing a convenient assumption.
Exercise 10: Public catalogue entry
Compress a five-field internal log into a three-sentence catalogue entry while preserving identity, media format, access restrictions and remaining uncertainty.
Self-check: underline every identity, measurement, permission, evidence qualifier and verb that indicates a completed or incomplete action. Explain which fields are safe to translate and which should remain exact tokens. If the task depends on unknown equipment, rights or collection practice, write a focused question for the responsible archivist rather than choosing a convenient assumption.
Frequently asked questions
What does ips mean in a tape log?
It means inches per second, a measure of tape movement speed. It should not be confused with an audio file’s kHz sample rate or kb/s data rate. Translate the unit, and preserve the original number rather than silently changing the technical claim.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.
Is mono the same thing as full-track?
No. Mono describes a signal arrangement, whereas full-track describes the physical use of tape width. A source can describe both, but one does not automatically prove the other. Keep those fields separate.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.
Can the translator fix inconsistent metadata?
Only by producing an explicitly documented correction after evidence review and with appropriate authority. For a faithful translation, retain the original discrepancy and flag it for the responsible archivist.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.
Should technical identifiers be translated?
Stable accession codes, filenames, checksums and shelf marks should normally be copied exactly. Translate the field label and surrounding explanation, not the characters that the archive uses to retrieve the object.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.
What if the box and reel have different titles?
Attribute each title to its source. A catalogue may later choose a preferred title, but the translation should not hide the discrepancy or silently rewrite physical evidence.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.
Does digitised mean restored?
No. Digitisation records conversion or capture. Restoration may include other carefully documented processes, and can be absent entirely. Unless the source states a restoration activity, do not add one.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.
What happens when the tape cannot be played?
Translate the attempt and result: inspected only, transfer not attempted, unstable replay, or partial signal recovered. Absence of a usable transfer is a valid preservation finding and should remain visible.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.
What is the safest way to translate a speed fraction?
Use a clear typographic representation such as 7½ ips alongside the source spelling when necessary. Conversion to 19.05 cm/s can assist readers but should not replace the original without a controlled style decision.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.
How should the translator handle an unknown speaker?
Describe the recording’s known channel or role labels and use “speaker unidentified” where appropriate. Do not infer names, genders, occupations or relationships from vague notes.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.
Is an MP3 copy automatically the preservation master?
No. File roles must be assigned by the archive’s workflow. A compressed copy may serve access, while another file is designated the preservation master, but a particular workflow must be checked.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.
What if an archive wants a very short public label?
Begin with carrier identity, approximate content description where supported, date confidence and access conditions. Keep more technical metadata in the structured record, with a persistent link.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.
How do I assess translation quality?
Run a field-level comparison for identifiers, quantities, qualifiers, source attribution, outcome status and access conditions. Ask whether a future archivist could find the same reel and know what happened to it.
A dependable answer remains tied to the particular record. Check the field label, its neighbours, the institution’s documented vocabulary and the evidence state before applying a general glossary rule. Uncertainty should be represented, not concealed.

Continue learning: contextual routes through translation and English
This page owns the specific task of translating analogue audio carrier and transfer records. It does not attempt to replace the general method for translating meaning, a broad terminology guide, a library finding-aid guide or an oral-history transcription manual. Use the following routes when the next difficulty concerns language interpretation rather than carrier documentation.
Translate meaning rather than words
Idioms, culture and non-literal language
Terminology, glossaries and quality checks
Archival finding aids and retrieval paths
A practical final test is simple: give the translated record to a colleague and ask them to retrieve the correct physical item, identify its documented format, state whether transfer was completed, locate the digital derivative and determine whether access is permitted. If the colleague cannot do all five without guessing, the translation is not yet finished.
