So essentially one project per song. Sounds sensible.

An export from the per-song project to mix the tracks.

I'd tend to hold the job the other way up, and run one final
audacity
project as a CD master session. I'd start by importing all
the mixed
tracks into the same project. They can then be trimmed if
needed, and
sorted into order. You can use audacity's normalise to set
the peak
level of each track if needed (and do any other adjustments
so that
actually sound right, which isn't the same thing). You could
optionally
compress at this stage if you feel it is a good idea.

I would then label up the tracks (sorry, does have to be
done by hand.
I'd like to see this automated, as I've described in another
thread),
and use Export Multiple to get a set of files to burn a CD
with.

So we can tidy up the number of import/export cycles a bit,
but in the
main it's still fairly manual work. The problem with trying
to automate
the trimming step is that it's very hard for the computer to
know what
to trim off - especially if the introduction that follows
the count in
is quiet.

This is fixed in the current CVS code. Not sure if it's in
any releases
yet, but this will be fixed in the course of time.

Thanks for the pointer. I ended up back tracking to 1.3.3
due to the 
soundtouch problem I just posted about. I think I'm current
now 
So, 
I'll give the muted stuff another go.

Best,
