About converting MP3 to AAC
MP3 is the most universally compatible audio format, playable on every device. AAC is an efficient lossy audio format that sounds better than MP3 at the same bitrate. Converting from MP3 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.
