Transcribing WAV files

WAV is uncompressed, which makes it the best possible input for speech recognition: no codec artefacts, nothing thrown away. If you have the choice, prefer WAV over a lossy format.

Export either a plain transcript or a subtitle file with timings — both come from the same run, so you do not have to choose up front.

FAQ

Why is WAV better than MP3 here?

WAV stores audio uncompressed. MP3 discards some detail to save space, and that lost detail occasionally turns into a misheard word.

Are WAV files too large to handle?

WAV files are big, but size does not slow down transcription — only the length of the recording does. A large 3 minute WAV processes just as fast as a small 3 minute WAV.

Can I export just the text?

Yes, the TXT export gives you the transcript with no timings.

Is the file uploaded?

No. Processing is entirely local, in your browser.
