sox(1) has a "silence" filter with lots of parameters. From its man
page:

"Removes silence from the beginning, middle, or end of the audio.
`Silence' is determined by a specified threshold."

That certainly would require a lot of fiddling, though. And of course it
won't be perfect. Because, how would you automatically determine whether
a certain passage is "music" or "non-music" ?

I think it is easiest to just use a waveform editor like Audacity and
chop off the parts that you *know* are the portions you don't want.
