How it works
Upload the WAV straight from your recorder or editor. Files up to 100 MB and 30 minutes of audio are supported.
Speech recognition works from the uncompressed audio and timestamps every line as it goes.
Correct names and jargon in the inline editor, then export as TXT, DOCX, PDF, SRT or VTT.
Why WAV files land here
WAV is what field recorders, Audacity, Windows Voice Recorder and most professional interfaces write by default, so it turns up whenever someone recorded deliberately rather than casually. That usually means good microphones and a controlled room, which is the best possible input for speech recognition. Upload the WAV exactly as it came off the recorder, because there is no need to convert it to something smaller first.
What WAV means for accuracy and file size
WAV stores audio uncompressed, so nothing has been thrown away before the recognizer hears it and there are no encoding artifacts to confuse it. The trade-off is size: stereo CD-quality WAV runs about 10 MB per minute, so the 100 MB per-file limit arrives around ten minutes of audio. Exporting mono instead of stereo halves that immediately, and speech loses nothing by being mono.

Transcription questions, answered
What people ask before transcribing a WAV file. Still have questions? Contact support.
Is WAV more accurate than MP3 for transcription?
Slightly, and only at the margins. WAV has no compression artifacts, which helps with quiet passages and overlapping speech, but a well-encoded MP3 of the same recording usually produces a near-identical transcript. Microphone placement matters far more than the container. This page is tuned for WAV, but other common audio and video formats are accepted here as well.
My WAV file is over the size limit. What now?
Export it as mono rather than stereo, which halves the size with no loss for speech, or split the recording into shorter sections. Converting it to MP3 first also works and costs very little accuracy.
How much audio fits in 100 MB of WAV?
Roughly ten minutes of stereo CD-quality audio, or about twenty minutes in mono. The 30-minute duration ceiling applies too, so whichever limit you reach first is the one that matters.
Does it handle multiple speakers?
It transcribes everything that is said, including overlapping speech, but it does not label who spoke. Clean recordings where people take turns produce transcripts that are easy to attribute by hand.
