This is a little more tricky :) and it all depends on the audio content a=
nd=20
the noise you're trying to suppress. There's no easy way to do this but y=
ou do=20
have the choice of a number of filters such as lowpass, highpass, bandpas=
s,=20
etc, but the place to start is probably the noiseprof and noisered filter=
s.=20
Again, have a look at the man pages.
