    About the M4A format

    M4A is the audio-only MP4 container, almost always carrying AAC audio. It is Apple's native format (iTunes, Apple Music, iPhone ringtones) and sounds better than MP3 at the same bitrate. Every modern device plays it.

    About the WAV format

    WAV (Waveform Audio) stores audio uncompressed as raw PCM samples, exactly as it was recorded or decoded. It is the standard for recording, editing and mastering because nothing is lost, and it plays everywhere. The price is size: a minute of CD-quality stereo takes about 10 MB.
