This repository implements a sound dereverberation algorithm proposed by Gilbert Soulodre:

Soulodre, Gilbert A. 2010. “About this dereverberation business: A method for extracting reverberation from audio signals.” In Audio Engineering Society Convention 129. Audio Engineering Society.

Note that this algorithm is patented (US Patent 8,036,767 B2).

See dereverberate.m for the algorithm implementation in MATLAB code. See audio for input files used to evaluate the algorithm and the implementation.

Here is a spectrogram representation of an example input (audio/EchoSample.mp3) and the algorithm's results on that input. To hear how it sounds, see the results folder.
