1. A loudspeaker capable of determining its location relative to other loudspeakers, comprising:
a plurality of microphones;
a plurality of drivers;
a processing circuitry; and
a memory, the memory containing a layout mapping application which directs the processing circuitry to:
receive a stimulus tone from each other loudspeaker in a plurality of loudspeakers using the plurality of microphones;
determine an angle at which each stimulus tone was received;
generate an impulse response for each received stimulus tone using each said received stimulus tone, each generated impulse response associated with the other loudspeaker from the plurality of loudspeakers which generated the received stimulus tone;
transmit the stimulus tone using the plurality of drivers;
receive, from each other loudspeaker in the plurality of other loudspeakers, a plurality of impulse responses, and a plurality of angles from stimulus tones were received by the other loudspeaker;
generate a distance matrix using the generated impulse responses and the received pluralities of impulse responses;
generate an angle of arrival (AOA) matrix using the determined angles and the received pluralities of angles; and
determine a location for each other loudspeaker in the plurality of other loudspeakers in a coordinate system.
