How to convert MP4 to WAV

  1. Drop the MP4 videos in. One or several, any length the device can hold.
  2. Pick mono or stereo. As recorded keeps the video's sound; mono halves the file for a voice.
  3. Download the WAVs. Named after the videos.

Why WAV from a video

Editing
WAV opens instantly in every audio and video editor and survives any number of saves without loss.
Sampling and music
Producers pull drums, vocals and ambience from video as WAV because it is what samplers and DAWs want.
Size
About 10 MB a minute in stereo. For sharing or listening, MP4 to MP3 gives a tenth of that.
