Abstract
Traditional surround sound experiences require precise placement of speakers at positions that are optimal for audio playback. Even after a careful setup, the audio experience may suffer depending on where the user sits relative to the speakers, since there is no way to intelligently adjust the equalizers for the different speakers distributed in space without localization information about the speakers. The techniques described in this disclosure utilize ultrawideband ranging to determine the relative position of different audio playback devices in an environment and the position of the user. A central node customizes the audio streams provided to each speaker device based on the determined position. If any of the speaker devices are moved to a different position or removed from the environment, if new speaker devices are added, or if the user’s position changes significantly to a different fixed location during playback, the central node can automatically adjust the audio stream for the new environment, without the user having to perform manual reconfiguration.
