Documentation-based guide · Official guidance checked October 5, 2026
You have a remote interview with a host and two guests. The recording folder contains separate speaker tracks, a mixed recording and a video export. Uploading the first file you find may be quick, but it can leave you transcribing the wrong mix, losing useful speaker separation or creating captions that no longer match the video.
Before opening Descript or Happy Scribe, make a small set of decisions about the source recording. The goal is to give the transcription service a sensible input while keeping enough context to correct mistakes later. This guide covers that preparation step, rather than the upload interface or a full transcript-proofreading process.
Basis: We checked the products’ official documentation on October 5, 2026. We did not upload a recording or measure transcription accuracy. The preparation checklist and interview example below are editorial recommendations grounded in that documentation.
Choose the recording before choosing the file extension
Start by identifying what each file actually contains. Is the mix complete? Does every guest appear? Are the separate tracks synchronized? Is one file an export of a compressed meeting recording while another is the original local capture?
Happy Scribe’s audio-quality guidance recommends using the original file. Converting an MP3 to FLAC does not restore information already lost through compression. A larger converted file is therefore not evidence of a better transcription source.
For our three-person interview, the best starting point might be the original synchronized speaker recordings, but that is a decision to make by inspection and listening. A separate track with missing passages is not automatically preferable to a complete mix. Keep both available until you know which contains the clearest, most complete account.
Listen at the beginning, middle and end
Sample several points before processing anything. At the beginning, confirm that the introductions and first question are present. In the middle, listen for quiet speakers, background sounds and overlapping answers. At the end, check that the recording continues through the final response.
This sampling is a practical screening method, not a guarantee that the rest of the file is intact. If you detect missing audio or a synchronization problem, investigate the full recording before committing to transcription.
Happy Scribe’s recording advice emphasizes a quiet room, a microphone close to the speaker and a wind shield where needed. It also notes the limitations of compressed call audio. For a recording you already have, these points help explain the source limitations; they do not mean an export setting can recreate details the call never captured.
If you consider cleanup, preserve the original and compare a processed copy against it. Check words with soft consonants, quiet replies and interruptions. Do not assume removing more noise will produce a more reliable transcript. Our Auphonic review explains a documented finishing workflow, but it does not establish measured transcription improvements.
Keep separate speakers separate when the workflow needs them
Descript lists WAV, MP3, AIFF, M4A, FLAC, OPUS and AAC among its supported file types. A supported extension does not guarantee a supported codec inside the file. Check the current codec combinations and your plan’s per-file upload limit in that document; channel handling matters too.
Its documentation says files with more than two audio channels are downmixed to stereo. If you need to preserve individual channels from a multichannel recording, split them into separate mono files before import. Keep the source file and document which channel belongs to which speaker.
For separate synchronized interview recordings, Descript’s sequence workflow can coordinate the tracks so edits apply together. Automatic synchronization is available, with manual alignment when required. Do not treat the availability of synchronization as proof that your particular files will align correctly.
Also avoid adding duplicate recordings of the same speaker to the transcription selection. Descript’s automatic-transcription guidance discusses transcription within aligned sequences and excluding duplicate same-speaker tracks. A host’s microphone track plus a mixed call recording can contain the host twice; deciding what should be transcribed is more useful than uploading everything indiscriminately.
Preserve the time origin if captions must match video
Before removing introductory silence or cutting an interruption, ask which video the captions will accompany. A transcript for reading can follow an edited audio file. Captions attached to the original video need timing that matches that video.
In our example, keep synchronized tracks referenced to their shared start point until the intended video edit is settled. If you remove 30 seconds from the audio but leave it in the video, timestamps tied to the edited audio will no longer describe the same moments.
This is a timing recommendation, not a product-specific limitation. The safe handoff identifies the exact audio and video versions used, records any changes to the beginning and avoids silently substituting a revised file. When you reach transcript proofreading, use our interview transcript review workflow for the separate final review.
Prepare names and language before transcription
Write a short speaker key: the host’s name, each guest’s preferred spelling and any organization or product names likely to appear. Include specialist terms that a general transcription system might misinterpret.
Descript’s transcription documentation includes language selection and a glossary for names and jargon. Set the language deliberately rather than leaving the decision unexamined; its language setting includes an option to ask each time. A glossary is useful context, not a guarantee that every occurrence will be correct.
If the interview changes languages, note where that happens and check the intended service’s current handling before beginning. Do not invent a single-language label simply because the opening conversation uses that language. Likewise, keep a short list of passages you already know are unclear so the reviewer can revisit the source.
Make a small, usable handoff packet
- Originals: Preserve the original files and work from clearly named copies.
- Chosen input: Identify the file or synchronized tracks intended for transcription, with a brief reason for that choice.
- Speaker key: List names, roles and track assignments, plus relevant specialist terms.
- Timing note: State the matching video version and any cuts or changes to the shared start point.
- Review notes: Mark known unclear passages, overlapping speech and language changes.
- Permission check: Confirm that you are authorized to upload the material to the selected service.
Keep the packet proportionate. A short interview does not need an elaborate production system, but it does need a clear answer to “which file are we using?” Names such as “guest-one-original.wav” and “interview-mix-for-transcription.wav” convey more than several exports all called “final.”
When the recording is ready
You are ready to proceed when the input is complete enough for the task, its speaker and timing relationships are understood, and the reviewer has the context needed to resolve uncertainty. The checklist cannot repair a clipped microphone or recover speech missing from the source. It can prevent avoidable confusion before you spend time on the transcript.
For Descript, pay particular attention to channels, aligned tracks and transcription selection. For Happy Scribe, start with the original recording and take its audio-quality guidance seriously. In either workflow, preserve the source, identify the intended output and leave unsupported words for human review rather than guessing them into certainty.
