| Abstract: |
This paper describes an implementation of a sound source localization algorithm in 2D space. To develop this work, it was used three microphones as receptors to capture the sound of a sound source, that using the cross correlation technique to measure the time difference of arrival among the three microphones it is possible to use trilateration techniques to estimate the localization. It is presented details of the techniques used to measure the sound delays among microfones and to make the trilateration. The developed software have enough quality to estimate the position of the sound source, considering a controlled environment without noise, but it is immature to be used on a real environment with the need of a real time response. It is presented some suggestions of techniques that can be developed to improve the precision considering noise and response time.
