Abstract
Methods, systems, and apparatuses are described herein for determining distances and angles between speakers and other home theater components for performance of calibration operations and functions. Distances are determined through timing playback of sweep signals from a reference speaker to the speakers, and also by timing playback the sweep signals between the speakers and a capture device at a desired listening position. Angles between the speakers and other theater components are determined based on the distances, and locations or mappings of the speakers and other theater components are determined from the angles and distances. The locations/mappings are utilized to perform different calibration operations. The calibration operations improve the user audio experience for speakers that are located in non-optimal positions for speaker configurations.
