Playing and Creating AAC Files
- Playing AAC
The default audio format used by Apple's iTunes and iPod is AAC. This is a variant of the MPEG standard, and as such has patent issues.
- Ubuntu 6.06 LTS (Dapper Drake)
Install the gstreamer0.10-plugins-bad-multiverse package. (Note: some people may need to also install gstreamer0.10-plugins-bad to make it work.)
- Ubuntu 5.10 (Breezy Badger)
You can listen to AAC files in rhythmbox or amarok by installing gstreamer0.8-faad. Songs purchased from the iTunes music store (.m4p) are encrypted and will not play using gstreamer0.8-faad. You will have to decrypt them first.
- Creating AAC files
First, you must install support for encoding AAC. For Ubuntu 5.10, install gstreamer0.8-faac. For Ubuntu 6.06 and later, install gstreamer0.10-ffmpeg. To encode to AAC from CDs, follow the instructions at CD Ripping. For other programs, you may be able to utilize FAAC directly to encode to AACs using the faac package. Or you could just try this:
sudo aptitude install abcde abcde -a cddb,read,encode,tag,move,playlist,clean -d /dev/cdrom -o m4a -V -x
