Abstract
A method for estimating an audio device location in an environment may involve obtaining direction of arrival (DOA) data for each audio device of a plurality of audio devices in the environment and determining interior angles for each of a plurality of triangles based on the DOA data. Each triangle may have vertices that correspond with audio device locations. The method may involve determining a side length for each side of each of the triangles, performing a forward alignment process of aligning each of the plurality of triangles produce a forward alignment matrix and performing a reverse alignment process of aligning each of the plurality of triangles in a reverse sequence to produce a reverse alignment matrix. A final estimate of each audio device location may be based, at least in part, on values of the forward alignment matrix and values of the reverse alignment matrix.
