[PD] microphone cleaner advice

[patrick]

hi,

i found this external:

drown~ was designed to function as a noise reduction
processor. It is an adaptive spectral filter which scales the
amplitude of frequencies that fall below a specifiable
threshold by scaling them by a specifiable amplitude factor;
this results in either noise reduction or noise increase.
drown~ thus provides a variety of possibly dramatic spectral
modifications that will bring you award-winning acclaim or
your money back.

well, i will forget about the noise cancellation, i don't want to make 
another microphone. i will try to simply implement something like:

remove low-frequency noise below 50 Hz (maybe not needed anymore (drown~)?)
drown~
bandpass filter (for voice *)
noisegate
global amplitude scaling (some kind of compressor)
limiter~
