Please can someone advise me. I'm using Audacity to digitise a bunch
of home-taped cassettes. Unfortunately some of them have a pronounced
hum underlying the music. Is there a way of damping this down.
Audacity has a bunch of filters written in Nyquist, but I'm not sure
what settings to use, BTW the hum is likely to be at UK mains
frequency of 50 hertz. Thanks - Chris B.
