!! Second attempt:
Found some more information at http://www.xena.uklinux.net/Linux/audio.html. This guy started using gramofile, and then switched to using gwc, the Gnome Wave Cleaner. I'm installing this right now, as well as snd and sox, which both claim to be good tools
+GWC works really well. I followed the suggested notes at the above URL, which I'll summarize here:
-(Still going)
+First of all, I amplified the track. GWC seems a bit buggy with this - it won't always amplify correctly. If the waveform doesn't increase in amplitude, it hasn't been amplified. I found if you wait till after processing to amplify, some noise still gets through.
+
+* Run the strong declick tool. The first time I ran this I got about 7000 clicks removed. The second time, about 400, and the third time, about 20. This was 'good' enough, so I moved onto the next step:
+* Run the decrackle tool. This removed most of the remaining crackle on the recording.
+* Run the denoise tool. Its suggested to use any lead-in you can, but I only lead-out noise available. It seemed to do just as well. I ran it first with the defaults, then used the suggested settings on the url above. It seemed about the same really, although with the speakers I have on this computer it is hard to tell.
+
+At this point, the tracks were a LOT cleaner and sounded great.
+
+Unfortunately, gramofile wont split the tracks out correctly any more. I figured I could run gramofile over the unprocessed track and use its timing, or I could split the waves up manually.
