Abstract:
Example techniques may involve performing aspects of a spatial calibration. An example implementation may include detecting a trigger condition that initiates calibration of a media playback system including multiple audio drivers that form multiple sound axes, each sound axis corresponding to a respective channel of multi-channel audio content The implementation may also include causing the multiple audio drivers to emit calibration audio that is divided into constituent frames, the multiple sound axes emitting calibration audio during respective slots of each constituent frame. The implementation may further include recording the emitted calibration audio. The implementation may include causing delays for each sound axis of the multiple sound axes to be determined, the determined delay for each sound axis based on the slots of recorded calibration audio corresponding to the sound axes and causing the multiple sound axes to be calibrated.

Claim (Index 18):
The media playback system of  claim 16 , wherein the one or more playback devices comprise a first playback device and a second playback device, and wherein causing audio output of the first sound axis and the second sound axis to be delayed according to the respective first and second delays comprises:\n sending, via the network interface to the first playback device, instructions to delay audio output of the first sound axis according to the first delay; and sending, via the network interface to the first playback device, instructions to delay audio output of the first sound axis according to the first delay.
