Extract Audio from Video

Extract Audio from Video saves the soundtrack of a video as an MP3, a WAV or an AAC file and drops the picture.

The video stream is discarded before any of it is decoded, which is why this is among the quickest tools here — only the audio is actually processed, however long the clip runs. MP3 goes through libmp3lame at a bitrate you set between 64 and 320 kbps, WAV comes out as uncompressed 16-bit PCM, and AAC is written as a raw ADTS stream. Only the first audio track is taken, so a film with a commentary or a second language keeps whichever track the file happens to list first. Up to five videos can be queued in one run, and a file with no audio at all is refused by name instead of yielding an empty result.

Extraction happens in the page, so an interview, a lecture or a recorded client call is never posted to a conversion service in order to get its audio out.

Turning a recorded interview into an audio file for transcription, keeping the music off something you shot, putting a lecture recording on a phone as MP3, and getting a WAV out of video for editing in an audio app.
