Why convert MP4 to WAV?
WAV is uncompressed audio: nothing is thrown away, which makes it the preferred format for audio editing, sound design, transcription software and professional tools. Converting MP4 to WAV extracts the soundtrack of your video as a 16-bit PCM file that any audio editor can open.
- You want to edit the sound of a video in Audacity, Adobe Audition or another audio editor.
- A transcription or speech-to-text tool asks for WAV input.
- You need an uncompressed copy of your audio for archiving or production.
Tips for the best result
- WAV files are big: about 10 MB for every minute of stereo audio.
- Converting to WAV does not improve the audio in the video; it just stores it without further losses.
- If you only want to listen to the audio, MP4 to MP3 makes a much smaller file.

Frequently asked questions
