Is this possible using transcode? If not, anyone know of (preferably F/OSS) tools that can do this?
Audio editing.  You can do this (as *.wav) with audacity.
Export as mp3 (or as wav, and use lame or sox to convert to mp3).

People seem to have missed that he needs to be able to script this.
That can be done with sox, where raw pcm can be generated from any
input, the pcm can be edited with perl/tcl/ruby/whatever, and the
results put back together using sox. It's not too hard to figure
out HOW to do it, but it is going to be a bit of work for somebody.

Exactly, but my first exploration into sox and soxmixer are more promising than a whole day before that, so kudos to you all, you've been a great help. I'm going to start interfacing soxmixer with a scripting language next week, am I ok to post my progress on this thread (for prosterity more than anything)? (considering its not strictly to do with transcode itself).
