I guess at the time I was thinking mostly of ecasound and sox, both of
which I've used very little, but every time I do I'm quite impressed as
to how much they encompass:

Ecasound documentation:

http://www.wakkanet.fi/~kaiv/ecasound/Documentation/examples.html

With this you can concatenate, mix, etc.

Sox - pitch shifting, time stretching, filtering, applying effects, etc.

http://sox.sourceforge.net/

Since you weren't terribly interested in the GUI based apps (I guessed
they weren't quite doing what you were thinking of doing) I thought I'd
suggest these.

Good luck,
Mark
