I haven't tried that with > rumble but it helps a bit with hiss/scratchiness. I did try that with gwc but didn't have much luck. But I didn't have time to play with all the different "settings". I'm especially interested in the "max and min frequencies to use in the noise sample" setting. There are lots of other ones and I haven't found any documentation yet that explains most of them. It seems like potentially a REALLY useful tool though it's UI could use a little work (Un-do is nice but Re-do is almost as necessary.) > >
