FIR Filter coefficients for voice

Hi All,

I would like to use a FIR block into a ADAU1761 for removing the background noise, how/where could I calibrate the right coefficients?


A simple pass-band filter isn't enough because the noise spectrum is overlapped to the human voice, then I would like test something "stronger" for getting a better quality into voice signal.


Thanks in advance
