[NFBCS] Audio SW optimized for voice cleanup?

[Ty Littlefield]

The way to remove any artifacts with an EQ is to sweep. Set your 
frequency at 200 HZ, set the gain to 20, and then sweep it up. when you 
hear the hiss, you can carefully notch out 1 db or so. Use the q to make 
finer cuts so that it doesn't affect other audio.

HTH,
