I'm trying ot clean up a WAV file that has a low sounding rumble, motor-like sound, sort of up and down. It's lower than the bass line. I'm finding this hard to describe in words. I'm using the Gnome Wave Cleaner and its got a notch filter but I don't know what frequency to set it for. I do know people hear from about 20 Hz to 20,000 Hz, on a good day, so would maybe 50 Hz to 100 Hz would be a good start? _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-user
