Possible Application Areas Audio localization has quite a few applications in the real world. In particular, such as system can be used in a home automation system to identify a person's location. Also, this project has applications in sonar and radar systems.

Objective In this project we would like to: Accurately determine the origin of a sine wave to within 22.5° Adjust to real-time change in the signal location However, first we need to set a few parameters. Firstly, our field-of-view is the half plane in front of the array and only deals with the azimuth, not the elevation. Secondly, as we will learn in Beamforming Theory, the signal will have to originate in the far-field. shows how our set-up will work.

The Setup The star represents our far-field source. The black circles represent microphones. The area shaded in green represents the correct region. The areas shaded in yellow represent our margin of error. The areas shaded in red represent the incorrect areas.
