About WAV and M4A Formats

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

What is M4A?

M4A is an audio-only MPEG-4 file popularised by Apple. It usually contains AAC audio (and occasionally Apple Lossless) and is the format used by iTunes and the iPhone Voice Memos app.

Commonly used for:

  • iPhone voice memos
  • iTunes music downloads
  • Audio exported from GarageBand

Why convert WAV to M4A?

M4A is the native audio format for Apple devices and keeps files small while sounding better than MP3 at the same bitrate.
