thanks, coachz. unfortunately, it's music so it's tonal and changes. for basic noise i usually just use reafft. tends to be kind of slow and cumbersome for this kind of thing, though, in my experience. in the past this is something i would have used samplitude's spectral editing for. very fast and versatile. easy to select tones and quash them visually. don't think reaper has anything of that level...yet. no longer have samplitude on the machine either.
