In this paper a Toolbox to generate and to analyze linear, non-linear, delayed and convolved mixtures of real source signals is presented. From one hand, in fact, a simple interface based on a physical model has been implemented and stereo, dolby, delayed, and convolved mixtures can be generated. On the other hand a Blind Source Separation analysis can be accomplished. In fact, a novel separation algorithm (i.e. APDP) is included in the Toolbox. Several experiments to separate delayed mixtures of real instruments are made. Three musical recordings of different instrumental scores are mixed and analyzed by using the Toolbox. Several comparisons with known methods are made.

Abstract

In this paper a Toolbox to generate and to analyze linear, non-linear, delayed and convolved mixtures of real source signals is presented. From one hand, in fact, a simple interface based on a physical model has been implemented and stereo, dolby, delayed, and convolved mixtures can be generated. On the other hand a Blind Source Separation analysis can be accomplished. In fact, a novel separation algorithm (i.e. APDP) is included in the Toolbox. Several experiments to separate delayed mixtures of real instruments are made. Three musical recordings of different instrumental scores are mixed and analyzed by using the Toolbox. Several comparisons with known methods are made.
