hi everyone,

i would like to clean a signal coming from a noisy microphone.

what i have in mind right now:

remove low-frequency noise below 50 Hz
bandpass filter (for voice *)
global amplitude scaling (realtime normalizer?)
limiter~
hip~ 5 (remove dc)

* The voiced speech of a typical adult male will have a fundamental 
frequency from 85 to 180 Hz, and that of a typical adult female from 165 
to 255 Hz

any advice is welcome (also patchs and externals).
pat
