Using Sound Juicer I am able to rip CDs very conveniently. I would like to rip them in about 256 kbit/s variable bitrate. To accomplish this I have defined the settings for mp3 in gnome-audio-profiles-properties (from gnome-media-profiles Install gnome-media-profiles) as follows:

audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 vbr-quality=0 ! id3v2mux

where vbr-quality=0 should give me a variable bitrate averaging 245 kbit/s. The resulting files however always say they are in 128 kbit/s.

When I change vbr-quality from 6 to 0 all resulting files differ in exactly 1 Byte only when comparing them with cmp file1.mp3 file2.mp3. This means vbr-quality settings have no effect here.

Would you please put the complete path to the option in gconf-editor? I'm not finding gnome-audio-profiles-properties – neves Oct 9 '14 at 0:34
@neves: it is an application... see edit. – Takkat Oct 9 '14 at 17:55

The setting for Lame are incomplete. We will have to define VBR mode 4 as well to obtain the desired results:

audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 quality=0 vbr=4 vbr-quality=0 ! xingmux ! id3v2mux
