About WAV
Waveform Audio File Format
A RIFF-based audio format from Microsoft and IBM, released in 1991, that almost always holds uncompressed PCM. CD-quality stereo takes about 10 MB per minute. Use it for editing, mastering and tools that want uncompressed audio; convert away from it to save space.
About M4A
MPEG-4 Audio
An audio-only MPEG-4 file, the format iTunes and Apple Music use. It usually holds lossy AAC and sometimes lossless ALAC. Use it for iPhones, Macs and iTunes libraries, where it plays and tags natively.
