Removing noise from audio using Fourier transform in Matlab
https://dsp.stackexchange.com/questions/9054/removing-noise-from-audio-using-fourier-transform-in-matlab
There are several simple noise tracking algorithms that perform well if the noise is relatively stationary. Based on the estimated SNR per frequency bin you mulitply each bin with a gain constant between 0 (terrible SNR) and 1 (no noise). Note that you only deal with magnitudes, the phase of the FFT is left unchanged.
