Sound source localization for circular arrays of directional microphones

Previous research in sound source localization has helped

increase the robustness of estimates to noise and reverberation.

Circular arrays are of particular interest for a number of

scenarios, particularly because they can be placed in the center

of the sources. First, that improves the sound capture due to the

reduced distance. Second, it helps on the direction estimation,

not only because of the reduced distance, but also because it

increases the angle differences. Nevertheless, most research on

circular arrays focused on the case of omni-directional

microphones. In this paper we present a new algorithm for sound

source localization developed specifically for directional

microphones. Results obtained from real meeting room setups

show a typical error of less than 3 degrees.
