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.
The free tier lets you upload files up to 5 minutes long with no signup required to try. Create a free account and you get 60 transcription minutes a month for longer files, exports, and history. 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.
Beyond file uploads
The same RecordX account handles new conversations as they happen:
- Chrome extension - records Zoom, Google Meet, Microsoft Teams, Webex, and Slack calls locally. No bot joins the room.
- Mobile apps - iOS and Android apps for in-person meetings, interviews, and site visits.
- Softphone - a built-in dialer with your own DID number for recorded phone calls.
- Calendar auto-join - connect Google Calendar so the app records the meetings you accept without lifting a finger.
FAQ
Are WAV files too big to upload?
Not usually. RecordX accepts large files - a 90-minute stereo 24-bit 48 kHz WAV lands around 1.5 GB and uploads fine over a normal connection. If you want to shrink it first, convert to 16-bit mono for speech and you cut the size roughly in half without losing intelligibility.
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.
