    About M4A

    M4A files contain AAC audio, which sounds slightly better than MP3 at the same size. MP3 plays on almost everything, so it's the safer choice for sharing. Songs bought from iTunes before 2009 may be copy-protected (M4P) and can't be converted.

    Voice memos are usually mono. Choose Mono under Channels to keep the MP3 small.
