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.

Included in the QuadMic 4-Microphone Array Package:

  • 1x QuadMic 4-Microphone Array

Features of the QuadMic 4-Microphone Array:

  • Four SPU0414HR5H MEMS Microphones

  • 100Hz - 10kHZ Flat (4dB) Frequency Response

  • 16kHz Sample Rate for Each Microphone
