Abstract :
In this work a design and a realization of multimodal microphone array algorithm development system which is proposed to develop new microphone array algorithm named MABox is presented. This device incorporates microphone array with four microphones, ADC cards and development software. Microphones are integrated in a separate directional box pointed to the speaker, the box is connected via USB and analog line to the computer. The development software environment allows us to test new beamforming algorithm. This system runs in real-time what allows us to change the structure of algorithm and its parameters.
