Abstract: A method for determining the orientation of a loudspeaker relative to a listening device is described. The method simultaneously drives each transducer to emit beam patterns corresponding to distinct orthogonal audio signals. The listening device senses sounds produced by the orthogonal audio signals and analyzes the sensed audio signal to determine the spatial orientation of the loudspeaker relative to the listening device. Other embodiments are also described.
