Audio signal acquisition using multiple microphones allows for concentrating on a specific sound source position and attenuating the sounds from other sources and ambient noise. The goal is to try several positioning schemes of microphones, acquire signals from multiple sources (all at author’s choice) and test several signal de-noising algorithms in MATLAB. Own suggestions on algorithms and their optimization are highly welcome.
