Convert MP4 to WAV
Free MP4 to WAV extraction - processed entirely in your browser, nothing is uploaded.
When the extracted audio is headed into an editor - Audacity, a DAW, a sampler - WAV is the right target: uncompressed PCM that every audio tool opens instantly and that survives repeated editing without generational loss. This tool decodes your MP4's audio track and writes 16-bit WAV, all inside your browser.

Frequently asked questions
Why choose WAV over MP3 for extraction?
Choose WAV when you'll edit the audio afterwards - effects, cuts, and re-exports don't degrade uncompressed audio. Choose MP3 when the extraction is the final product and file size matters.
Why is the WAV file so large?
WAV stores raw uncompressed samples: about 10MB per stereo minute at CD quality. That's the price of a format that loses nothing and opens everywhere.
