He eventually got the microphone array working, but not the onboard digital signal processor (DSP). ... Lua and C/C++, and it looks like the coprocessor features an Arduino-compatible bootloader.

Near-field beamforming divides the space directly in front of the microphone array into a 64x64x64 grid of 5cm voxels, and can locate a sound source in that 3d space.

This microphone-shaped piece of circuitry was made with Arduino compatibility in mind, which means that voice search is just the beginning.

InvenSense’ ICS-52000 is a low noise microphone that allows a microphone array to connect directly to digital processors without the need for audio converters in the system.

ClearOne, a global provider of audio and visual communication solutions, announced today that it has been awarded a new patent relating to Beamforming Microphone Array Systems. U.S. Patent No ...
