[LAU] removing hiss from samples

What comes to my mind (I only used it once though) is Gnome Wave 
Cleaner: http://gwc.sourceforge.net/ already mentioned in the past on 
this lits. It even has a gui!

I thought that, although pretty old (last software update 2003?) and 
aimed at something different (old LPs), I'd mention Gramofile which also 
did some kind of noise (hiss, crackle etc.) reduction (no gui but quite 
easy to use). I used it about 4/5 years ago and didn't seem bad (your 
mileage may vary).
