I had heard that Mac was producing an MP4 format for sounds that is going be compressed tighter than MP3, also it's going be a Public Domain format. (FREE) no license will be needed.
Would like this confermed if anyone knows about it.
You can currently export AAC audio files (audio format used in MP4) using QuickTime Pro. You can get much better sound quality at a given bitrate using AAC encoding as opposed to creating a MP3 file. If you want to compare the same file compressed with mp3 or aac you can download a song that has been compressed with both at my brother's website:

Just scroll down the page and click on the "Free Mp3 Download" link. The page it takes you to has both an mp3 and mp4 file. The mp4 file is compressed at a lower bitrate and is about 500k smaller. This will allow you to compare quality. Also, the audio player (link on the left of page) that lets you sample his music is all compressed using aac but with a higher quality then the free download.
