WAV to text
Upload a WAV file and get a clean, speaker-labelled transcript with timestamps and an AI summary. Works free on the RecordX free tier.
What this tool does
WAV is a lossless container. Field recorders, DAWs, and studio interfaces still write to WAV because it preserves the original PCM samples with no compression artefacts. That is exactly the sort of audio a transcription engine likes to see: clean highs, uncompressed sibilance, honest room noise. Drop a WAV into RecordX and you get every word back, split by speaker, with a timestamp on every turn and an AI summary at the top.
Open a free RecordX account and you get 60 transcription minutes a month, plus a Word (.docx) export of every transcript. Same engine that powers the paid plans.
How it works
- Upload the file. Sign up at recordx.io, open the web app, and drag your file into the upload area.
- Wait for the transcript. Short files come back in seconds; longer files a few minutes. Speaker separation and the AI summary run automatically.
- Download or ask the AI. Read, edit, and export the transcript, copy the summary and action items, or ask questions of the transcript in the built-in editor.
Formats supported
WAV files in any common PCM configuration - 16-bit, 24-bit, mono or stereo, 8 kHz through 96 kHz. RecordX also handles the usual friends the same session tends to produce: MP3 bounces, M4A voice memos, FLAC archives, OGG exports.
What kinds of WAV files work
- Interviews - one or two microphones, quiet room. Best-case audio for transcription.
- Podcast masters - the pre-loudness-normalisation WAV before you bounce to MP3.
- Field recordings - ZOOM, Tascam, Sound Devices - the standard portable-recorder output.
- Studio sessions - the raw stereo mix straight out of a Pro Tools or Logic session.
What you get back
Speaker-labelled transcript
Turns split by speaker. Rename Speaker 1 / Speaker 2 to real names in one click.
Timestamps
Every segment carries a timestamp so you can jump back to the audio moment.
AI summary and action items
A one-paragraph summary, a bullet list of decisions, and a checklist of follow-ups.

- Softphone - a built-in dialer for recorded phone calls, on team and Business plans.
- Calendar auto-join - connect your Microsoft Outlook / Microsoft 365 calendar and a notetaker joins the meetings you accept.
FAQ
Are WAV files too big to upload?
Uploads cap at 500 MB. A stereo 16-bit 44.1 kHz WAV uses about 10 MB per minute, so an hour fits comfortably. Longer or 24-bit sessions can exceed the cap - convert to 16-bit mono for speech first and the file drops to roughly a quarter of the original size with no loss of intelligibility, or upload a FLAC instead.
Do I have to convert my WAV to MP3 first?
No. Upload the WAV as-is. RecordX does the format handling on its side.
Which WAV sample rate is best?
16 kHz is the transcription sweet spot for speech, but 44.1 kHz or 48 kHz WAVs work just as well - the engine resamples for you.
Will speaker separation work on a single-track WAV?
Yes. Speaker diarization runs on the audio content, not on channel splits. Even a mono WAV comes back with Speaker 1 / Speaker 2 turns you can rename.
