This has been on me "todo list" for years!  There are some
filtering examples and click removing/smoothing functions
scattered around, but nothing that really tries to clean
up a recording.  I think some cmdisters have mentioned
gwc (Gnome Wave Cleaner), and a long time ago Matti Koskinen
had some wavelet-based code (if I remember right). Someday
I'll have time to look at this problem in detail -- it's
not an easy problem, I think, if you want to keep the
original's "brightness".  (Current functions in Snd
include anoi, remove-click, smooth-*, various low-pass
filters, and fft-squelch -- see extsnd.hmtl and sndscm.html).
