Hi Jesse, hi everybody else,
output as AC3 is exactly what I need and I'm glad somebody made the
effort creating such a tool.

If you interpret "LFE channel" as a "subwoofer channel" than you're
right - I don't need it. But the front center - I think - I do need:
e.g. one guitar on the left front channel, the second one on the right
channel and the drums on the center speaker (just an example, needs a
lot of fine-tuning ;-)). Am I right I can change these "balance
positions" during time by this "automation" function?
A question regarding performance of jack/ardour as Allan stated he has
2.9ms latency: What window manager are you using? I'm using Gentoo, too,
but right at the moment I'm stuck with KDE 3.4 (XFCE4 is still
compiling). Right now I'm using the normal gentoo-sources because I'm
new to AMD64 and wanted to check everything without ck-sources (I had
them installed on my old AMD AthlonXP). What other performance tips can
you give me besides switching over to ck-sources and XFCE4? I've JACK
running in realtime mode, have /dev/shm mounted (how can I check JACK is
really using it) and still get LOTS of xruns when JACK is just idle
(Frames/Period: 512; Sample Rate: 48000; Periods/Buffer: 2). Right now
doing an "emerge -uDav --new-use world" (full cpu load) I don't get them
any more but I had them earlier the day just starting JACK with qjackctl
... I'm just curious where I can enhance the performance for JACK/ardour
so I get no more xruns. Tomorrow I'll replace KDE with XFCE4 and see how
much that is going to speed things up.
Thanks for all your responses, you helped me a lot already!
Best wishes to everyone
