The ROBOEAR by Brian Beard
Kit includes everything seen on the product detail picture.
The ROBOEAR (Robot Ear) is designed to find the direction to nearby sound sources, which in psychoacoustics, is called 'localization'. Humans can usually localize a sound to ± 10 degrees. The ROBOEAR's 8-bit PIC microcontroller and three microphone array use amplitude comparison and acoustic cross-correlation to localize sounds. The ROBOEAR can also function as an audio acquisition front-end for more powerful computers. Communication with the host computer is jumper selectable as either serial UART, or SPI.
