Guide aac kaudiocreator
In KAudioCreator (the standard KDE CD ripper), you can configure the encoder part to call FAAC, the Free Advanced Audio Coder.
In the Settings menu, choose Configure KAudioCreator, and open the Encoder pane. Click the Add button, and point to the faac binary. Then click on the Configure button and configure the name of the encoder as FAAC, the Command Line as "faac -o %o -q 150 -c 22000 -w --artist %{artist} --title %{title} --year %{year} --album %{albumtitle} --track %{number} %f" and the Extension as m4a.
Adjust the -q (quality) and -c (cutoff frequency) parameters to suit your usual requirements.
Now you are all set to rip CDs directly to AAC files.
