ELI5: Why is 320kbps the standard bit rate for music and not higher?
gpt
Essentially, MP3 was developed to compress CD quality audio to certain bitrates without noticeable loss of quality. Much of the encoders targeted 128kbps or 192kbps, which is pretty much nominal - it sounded good, but other codecs (Vorbis and AAC) started kicking MP3's butt at those bitrates. 320kbps is nearing the upper range of what's actually "worthwhile" with MP3 - increasing the bitrate won't increase the quality anymore.

So the short answer is, MP3 algorithm as a whole doesn't offer much benefits over 320kbps. It's pretty much as good as MP3 gets. Other algorithms might be worth a try, or you could just use a lossless compression algorithm like FLAC.
