I am running Ubuntu 13.04 x64 and I am trying to RIP audio CDs to AAC using Rhythmbox, I already installed gstreamer and faac and I can select to rip to MPEG4 under Rhythmbox preferences but I cannot change the default settings. By default it will RIP the CDs at 128000 bitrate, this is what I want to change to 256000. I already tried using gconf-editor to edit the preferences in the AAC profile but no luck. I am not new to Ubuntu and in the past I used to RIP my CDs to OGG but my wife got an stupid iPhone and it does not reads OGG and I do not like the gap between tracks usually found in MP3 files.
Any help will be much appreciated.
