This is the second part of an audio filtering project (in general, signal processing). This sample shows a noisy recording of my voice, after transforming the signal using the xft (extended fourier transform), applying a filter to cut some frequencies and later applying the inverse xft. All this done with an algorithm in matlab or mathematica written by me. Check the recording before the filtering process by hearing the file "holaoriginal. Wav" and please comment.
