Nope, just quality 6 in both cases, nothing fancy. Done with abcde for
vorbis-tools (just a shellscript that calles oggenc with the parameters
I specify) and sound-juicer on gnome for gstreamer.
Sound-juicer is at least twice as fast.

And that's the reason I'm surprised there is such a great difference in
This is very intersting, I'll have to look into it more closely :)
