Here is an overview of the project.

The processor will receive real-time audio samples of the environment through two (2) microphones connected to the A/D ports.  The reference signal must be programmed by playing the signal and pressing the "learn" button.  The LEDs will blink then the signal is stored.

Optionally, if the reference signal is sensed, it will determine the direction of the signal by calculating the delay of this signal from the multiple sources.  The direction will be displayed on the LEDs relative to the two microphones.

Please follow the links on the left for specific information.  A block diagram is shown below:
