Comment 50 for bug 195483

Wow, just updating from a LiveDVD session of Maverick Alpha3 to let folk know that, after adding sound-juicer and ubuntu-restricted-extras, 'Audio CD Extractor', aka Sound Juicer's default Quality MP3 profile is now audio/x-raw-int,rate=44100,channels=2 ! lamemp3enc name=enc target=0 quality=6 ! xingmux ! id3v2mux, which then defaults to creation of 32K-320K VBR instead of 128K CBR MP3s.
After applying sudo apt-get install gstreamer-tools and running gst-inspect lame to consult the LAME settings, I then changed quality=6 to quality=2, which sounds subtly better to my reduced frequency response ears and a lot better to those with keener hearing !
I may now consult a forum genuine audio expert to see whether further 'tweaks' should be made, but it looks like positive progress is now being made.
