About WAV (Waveform Audio File Format)
Uncompressed PCM audio — a bit-perfect copy of the recording with zero quality loss. WAV is the standard for studio work, DJ sets, mastering, and any workflow where the file will be edited or processed again. The tradeoff is size: roughly 10 MB per minute of stereo audio at CD quality.
Best for: studio editing, mastering, DJing, archiving masters

M4A vs WAV: what changes?
M4A is a lossy compressed format, while WAV is lossless. Converting to WAV will not restore quality that M4A compression already discarded — but it gives you an editing-safe, universally compatible file that won't degrade further with processing, which is exactly what studios, DJs, and mastering engineers need.
