Are you talking about the FFT > filter? Would you be able to describe how to use it? Hit and miss? i can't remember if it was already present in 1.1.3, but in 1.2.0 there's a noise removal plugin (not the fft filter plugin). it works like many other similar plugins: first you select a portion of your file where there's only noise, no signal, then the program designs an fft filter based on that noise. that filter is later used it to remove that noise from all the file or whatever part of it you select. i used to use a similar plugin in windows, this one is simpler but seems to work in it's way. the principle is simple enough. i _think_ snd has a similar function, but you won't find it in any menu, you'll have to type some command in the listener (never leaned to properly use snd myself...).
