Certainly that would make removal of the ads easier, but finding them -
if the podcast files are random extracts of longer files (ie the ads
may be anywhere at all in them, not eg always around the - say - 4 mins
in point, is still going to be tricky.

Assuming that one can near-instantly id something as jingle or ad if one
clicks play at some point on a timeline, one's still going to have to do
that manually maybe 30 times (ie every 20 seconds) in a ten-minute file.


It might still be easier to use a script to generate (say) 2-second 
snips
of each source file at 20-25 second intervals, then concatenate them and
listen to a set to find out if any of them seem to contain ads/jingles.

I think that too.
