Extract the audio from a video, as a WAV file
Get the voice, music or interview audio out of a video in seconds. Choose stereo or mono, trim the start and end, listen, and download an uncompressed WAV. The video is never uploaded.
To extract audio from a video, open the video here; the browser decodes its sound track in a few seconds. Optionally set a start and end time and choose mono, then click Save WAV. The result is an uncompressed 16-bit WAV file, which every editor and player opens. The tool doesn't make MP3: WAV keeps full quality but is larger, about 10 MB per minute in stereo at 44.1 kHz.
3 steps, a few seconds
