An application to acquire audio signals with chicoplus hardware

In this paper we present a method to acquire the overall signal (signal of interest plus interferences plus noise) impinging upon an array of 4 microphones. This is achieved by using the “Chico Plus” audio recorder card, by Innovative Integration, a Borland C++ Builder 5 program to develop an application for the user communicating with the card, an array of microphones, and some filtering algorithms implemented with MatLab. We also want to compare the results obtained using these real signals with those ones got with simulated signals described in previous work.
