    About ALAC and M4A

    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.

    M4A: M4A is an MPEG-4 container holding AAC audio. It sounds better than MP3 at the same size and is the default format for iPhone voice memos, Apple Music downloads and many Android recorders.
