MATLAB code implementing a source-filter model based on the beta-divergence. Details about the method can be found a supplementary technical report (see 'Publications' tab).
The repository contains a MATLAB class 'CSourceFilter' implementing the model. An example script 'sourceFilterExample' illustrates the use of the class and some supplementary files for the example script are provided.
There are no prerequisites for the class other than a basic MATLAB installation. The additional files 'dceps' and 'idceps' implement the 'discrete cepstrum spectrum envelope' from D. Schwarz' thesis (see reference in ICASSP paper). These are only required for the estimation of the smoothed version of the estimated filter curve.
