Thanks. Audacity appears to be a nifty, fairly comprehensive app, but unfortunately way too complicated (or confusing) for me to use. It sure isn't a simple "cut-and-paste" procedure.
I can open the podcast, isolate regions of it, but cannot manipulate by any means the parts I've isolated (in spite of attempting to follow the accompanying manual's instructions). So essentially what I've got is an mp3 player with a wave form that I can gaze at.
C'est la vie.

EDIT:
Reading further through Audacity's notes, I find that I would need to download and install the optional LAME MP3 encoder in order to export the "Audacity project" as an mp3 file (even though the podcast is already in mp3 format).

So it really is more complicated and convoluted that it was touted to be.

Back to square one.

Aside: Reading the 50th anniversary edition of Thomas Kuhn's The Structure of Scientific Revolutions is a cakewalk compared with Audacity's manual.
