Voice Audio Processing

Basic processing of audio samples in wav format, using fourier transformation.

This is a set of scripts solving basic tasks for the processing of the human voice:
analysis of the spectrum
spectrum control equalization
spectrum shifting (up/down)
squaring
thresholding
It shows time-frequency duality, how to properly maipulate the FFT coefficients, how to plot the spectrum.
It contains a set of wav files to test the scripts and it's funny to listen to the audio produced: like metallic voice or male\female effects.
