At a glance
- Identify source, participants and duration.
- Check actual sound and completeness.
- Retain unmodified recordings beside edited derivatives.
- Link consent, transcripts and backup records.
Identify the recording and its carrier
Distinguish born-digital audio from a tape or disc that requires transfer. Record the source, participants, occasion, date, duration and any labels. A cassette case and its tape can be mismatched; treat the label as evidence to verify.
For digital material, preserve the highest-quality surviving original and document exports. Converting an already compressed recording to an uncompressed format cannot recreate discarded information.
Document the listening context
Listen to representative beginnings, endings and transitions, and check completeness against any recording notes. Record silence, interruptions, missing sections and uncertain speakers. Use headphones or monitoring appropriate to the task without assuming a visible waveform proves intelligibility.
Keep a transcript or time-coded summary with the recording identifier. Correct searchable text against the audio. Mark uncertain words rather than smoothing them into an invented statement.
Keep access and preservation separate
Retain an unmodified original and document any noise reduction, cutting or normalization on a working copy. Make a convenient listening copy for the intended audience. Export technical and descriptive metadata alongside the files when the original application may not remain available.
For physical recordings, condition and playback equipment matter. Do not repeatedly play a damaged or irreplaceable carrier to experiment. Ask a qualified audiovisual preservation service to assess fragile or unfamiliar media.
Record consent and verify copies
Store consent and access conditions in the appropriate restricted location, connected to the recording. Private possession does not automatically authorize public release of every voice or statement.
Check the transferred copy by playback and file verification. Maintain independent copies and keep the log of transfers so a future custodian can distinguish the original recording, the transfer and edited derivatives.
WORKED EXAMPLE
Put it into practice
OH-007: original recording, 42 minutes; transcript OH-007.txt; 18:24 name uncertain; listening copy has a shortened introduction, documented separately.
Illustrative example, not a historical record.
