QuadMic 4-Microphone Array for Raspberry Pi
QuadMic 4-Microphone Array for Raspberry Pi
The QuadMic Array is a 4-microphone array based around the AC108 quad-channel analog-to-digital converter (ADC) with Inter-IC Sound (I2S) audio output capable of interfacing with the Raspberry Pi. The QuadMic can be used for applications in voice detection and recognition, acoustic localization, noise control, and other applications in audio and acoustic analysis. The QuadMic can be connected to the header of a Raspberry Pi computer and used to record simultaneous audio data from all four of its microphones. Some applications of the QuadMic are: characterizing noise sources, room and spatial geometries, and other aspects of acoustic systems.
