    About ALAC and M4R

    ALAC: ALAC is Apple's lossless format. It compresses audio to roughly half the size of WAV with zero quality loss and plays natively in Apple Music, iTunes and on every iPhone. It is saved with the .m4a extension.

    M4R: M4R is the iPhone ringtone format. It is an AAC audio file (the same as M4A) with a different extension, and iOS only accepts ringtones up to 30–40 seconds long.
