WAV and M4A, explained

WAV is uncompressed audio: exact, but big, about 10 MB per minute of CD-quality stereo. It's the format to edit in.

M4A is AAC audio in an MP4-style file, Apple's usual audio format (Voice Memos, GarageBand, iTunes). It sounds a little better than MP3 at the same size.

Going from WAV to M4A makes the file much smaller. M4A is lossy, so at low bitrates you lose some detail; at 192 kbps or more most people can't hear a difference.
