Voice Audio Processing

version 1.0 (2.81 MB) by

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



No License

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)
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.

It's a very effective way to show how FFT works and also the applications are very practical.
