m4a
Apple audio format
M4A is an audio file format using Apple's container for AAC-encoded sound.
It's essentially the audio-only version of MP4 video files, commonly used for music purchased from iTunes and other digital stores.
The format offers better compression than MP3 while maintaining audio quality: I converted all my songs to m4a to save space.
