Blue : sensors, Green : candidates, Red : estimated sound source.
Audio Localizer is the final project for Introduction to Sensors, Instrumentation, and Measurements (ISIM).
It is based on an aggressive band-pass filter around clap frequency (20 kHz), to localize the sound source.
The Arduino acts as the communication channel between the four sonar sensors and the servo.
Computation occurs on the main computer with SymPy, and returns the result to the arduino.
The location is visualized with PyQt4.
Arduino then takes the input and, based on the identified location, rotates the arrow mounted on the servo to point towards the sound source.
