Thanks. After posting that I Googled the definition, and tried that, but it made it sound not good at all. I'm now experimenting with Audacity's noise removal at a lower setting than I'd used before, and it appears to be doing a better job. The FFT filter is just worthless, because the UI is not specific enough (I can't tell exactly what frequency I'm telling it to drop off to nothing at). -- David W.
