This Acoustic Impulse Marker project by Adam Wrobel and Michael Grisanti of Cornell University uses 3 microphones to listen for sharp sounds, when a sound is detected the arrival time of the sound to each of the 3 microphones is used to determine where the sound came from. The project uses a ATmega 1284p microcontroller to process the microphone input but analog stages are used to convert a fast
