The two-way sound systems require time alignment procedures between different speakers using audio processors. Framed in this object of study, this article describes the implementation of a software tool for the analysis of sound systems. This tool was developed in the visual programming environment Matlab ®, Simulink ®, and is useful for evaluating the performance of a sound in an enclosure through the analysis of the frequency response of the same, which is affected by the acoustics of the room. Tests show that the software is reliable, presenting relative errors less than 4% in the different modes of operation.
