Abstract
The basic idea of providing a noise filter is that you take a signal, with added noise, perform an FFT on the signal, remove all spectral harmonics that have a PSD below some threshold, and then take the IFFT. Selecting the PSD threshold for noise can be tricky. What works well on a synthetic sound might turn a sampled sound into silence.
