What format are voice memo files on the iPhone?

The Voice Memos app on iOS devices is a convenient way to record audio on the go. Recordings are stored directly on the iPhone, iPad or iPod touch and can be synced with iTunes.

Voice memos are saved using the MPEG-4 file format, with an extension .m4a. These files can be played by a variety of applications including iTunes, QuickTime, and Windows Media Player.

iOS 7 also records a .waveform file that is associated with each audio recording. This provides a visual graph of the sound in the Voice Memo app.
