Update: I've been kinda unhappy with the way Gramofile finds track
boundaries, so today I went looking to see what else is out there. I found
a program called Gnome Wave Cleaner (gwc). Looks like it does a much
better job at cleaning up clicks than Gramofile, but it has no ability to
split tracks.

However, I found that WAV files cleaned up with gwc split much cleaner in
Gramofile, probably because a lot of the inter-track noise is gone.

Go to Google and do a search on "linux declick". There are links to gwc on
the first page of hits. There are a couple of libraries that must be
downloaded and compiled. On Fedora Core 1 I found that gwc would not
compile until after I compiled and installed the libraries, then (critical
point) updated /etc/ld.so.conf and ran ldconfig. After that gwc compiled
and installed cleanly.
