M4A vs WAV
WAV is lossless, but it can't restore detail already removed by M4A's compression — the file just gets bigger. Convert when an app or editor requires WAV.

About M4A and WAV
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.
WAV: WAV stores uncompressed PCM audio, so it keeps every bit of the original sound. Files are large, but WAV is the standard for audio editing, studios and professional software.
