About M4A and WAV Formats

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

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 M4A to WAV?

Voice memos and iTunes tracks often need to be WAV for transcription services, editing software or older Windows tools.
