how to eliminate background noise? I´m using NAudio
I do that the hard way: I have some sound data which contain "noise" only. The noise is anaylzed with a Fast Fourier Transformation (FFT), thus I get frequencies and signal strength. Next, the audio sample to be filtered is also analysed with the FFT. If the signal strength at a frequency is less than the signal strength in the noise at that frequency, that strength is farther reduced (down to 0). Then the FFT is applied again to get the clean sound signal. I do not know which classes NAudio provides for that purpose. But I am pretty sure they'll do it in a such a way too.
