About MP4 and WAV Formats

What is MP4?

MP4 is the most widely used video container. Its audio track is almost always AAC, though it can also carry MP3, AC-3 or ALAC.

Commonly used for:

  • Phone and camera videos
  • YouTube and social-media downloads
  • Screen recordings

What is WAV?

WAV was introduced by Microsoft and IBM in 1991 and stores audio as uncompressed PCM samples. CD-quality stereo WAV (16-bit, 44.1 kHz) uses about 10 MB per minute, and every audio editor, DAW and media player can open it.

  • Recording, editing and mixing in any DAW
  • Mastering and archiving at full quality
  • Broadcast, sampling and sound-design work
  • Maximum compatibility with hardware and software

Why convert MP4 to WAV?

Extracting the soundtrack as WAV lets you edit dialogue or music in an audio editor, transcribe it or use it as a sample.
