Where WAV Files Come From

Field and handheld recorders
Audio interfaces and DAWs
Archives and broadcast

Zoom, Tascam and similar recorders save WAV by default — interviews, lectures and location sound.

Field and handheld recorders

Podcast tracks recorded in Audacity, Reaper, Logic or Pro Tools usually export as WAV.

Audio interfaces and DAWs

Radio, oral history and research archives keep master copies as uncompressed WAV.

WAV at a Glance

WAV stores sound without compression, so files are big but nothing is lost. For transcription, bigger is not better beyond a point — this is what matters.

Before You Upload

Three things worth checking with WAV files.

4 GB

Long takes may be split

Classic WAV stops at 4 GB, so many recorders split long takes into several files. Upload each part, or join them in an editor first.

Channels

Silent or noisy tracks are mixed in

Recorders with several inputs write them all to the file. Mute or delete an unused, hissing channel before upload for a cleaner transcript.

Upload time

Convert only if your connection is slow

Converting to MP3 makes the upload ten times smaller without hurting recognition. Our free converter does it in your browser.

Frequently Asked Questions

WAV to text: common questions.

All questions
No. Speech recognition works at 16 kHz mono, so higher sample rates and bit depths only make the upload longer. What helps is a clear, close microphone.
Only if the upload is slow. A 128 kbps MP3 is about ten times smaller and transcribes just as accurately.
All channels are mixed into one before recognition, and speaker labels separate the voices in the transcript.
Up to 8 GB per file, which is around 12 hours of 44.1 kHz 16-bit stereo audio.
You get 30 free minutes once, with no credit card: short files are transcribed in full, long ones show the first 10 minutes.
