Subject: [linux-audio-user] Best SW for extracting & arranging short clips?

I'm a list newbie, though a Linux oldie. One of my side hats is
giving occasional lectures on opera, which I illustrate with very
short (15-45 seconds) clips lifted from my CD collection. My problem
in the past has been that it can be very time-consuming to prepare the
clips, since it's not practical to cue up a CD of the complete work in
the middle of a lecture.
My procedure so far has been to first rip the entire work to a .wav
file as a unit. Then I listen, making note of the rough time offsets
of things that might be useful in a talk. So far, I don't think I can
do any better.
The painful part comes in collecting the clips. I use xmms to return
to the clip in question, this time taking careful note of the start
and end offsets. Then I use sox's "play" command to do a test
extraction to find out if I picked the right boundaries. In the same
parameters, I specify (i.e., guess at) the fade-in/out I need. It
often takes 3-4 trials and errors to figure out the correct
parameters. Then I have to do another extraction to a file, and
repeat the whole thing for the next clip.
Working the way I do now, I probably spend 3-10 minutes on each clip.
Then I have to build a .toc file so I can burn the final CD with cdrdao.
I'm wondering if there is any GUI software that would ease this task.
I'm thinking that if I could just grab a pointer and drag it back and
forth, sort of like rocking tape reels, I could pick my start & end
points a lot more quickly. If I could then pipe that chosen portion
into a script of my own devising, I think I could make the remaining
steps relatively simple. I looked at snd (very briefly) but haven't
had time to experiment yet.
It would also be nice (though hardly critical) to have something that
would let me drag-and-drop the extracted clips to arrange them and
build a .toc file.
Anybody have any recommendations?
