About converting M4A to AAC
M4A is an AAC-based Apple audio format with good quality at small sizes. AAC is an efficient lossy audio format that sounds better than MP3 at the same bitrate. Converting from M4A to AAC swaps one for the other without changing the underlying content.
Pick your target bitrate before converting, and you can also drop in a video file to pull out just its audio track.
