About WAV
WAV is the working format: uncompressed, universally compatible with editing tools, but large. A recording session in WAV is the right way to capture audio for editing. The WAV is what you export from your DAW, not what you distribute.
About M4A
M4A uses AAC encoding — technically more efficient than MP3 at the same bitrate. A 128 kbps M4A typically sounds better than a 128 kbps MP3. It is the format Apple Podcasts recommends for submissions, the default for iTunes imports, and the native format on iOS. File sizes are comparable to MP3.
When to convert WAV to M4A
Podcasters are the primary audience here. You record and edit in WAV, then need a distribution-ready file. Apple Podcasts explicitly recommends AAC-encoded audio (M4A) at 128 kbps mono or 192 kbps stereo. If your host accepts M4A, this gives you a marginally better-sounding compressed file than MP3 at the same bitrate — which matters most at lower bitrates. Music producers distributing content through iTunes also export as M4A. Beyond Apple's ecosystem, M4A has broad support: Android, Windows, and most streaming services all handle it. The one limitation is older hardware — car stereos, legacy players, and some broadcast tools prefer MP3. If compatibility is the priority above all else, choose MP3 instead.
