In this project a system to beam steer the sound waves based upon the location of a listener in the room was designed. The concept is modeled after a phased arrays which use a progressive time delay calculated based upon the distance between speakers and the desired steering angle. Infrared sensors were used to determine the location of the listener which is used to determine the proper delay value. Each time delay value has a corresponding, unique, resulting steering angle of the beam. The basic implementation of the system obtains analog audio input which is sampled and converted to a digital value. The delay is then applied to the samples playing out of each speaker. The samples are then converted back to an analog waveform which is filtered, amplified, then outputted.
