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 14):
The method of  claim 8 , wherein determining the first arrival time and the second arrival time comprises:\n determining first and second impulse responses corresponding to the respective first and second slots; aligning the first and second impulse responses to a respective first reference point; identifying respective second reference points in the first and second impulse responses; determining a first difference between the first and second reference points of the first impulse response; determining a second difference between the first and second reference points of the second impulse response; and determining first and second arrival times based on the respective first and second differences.
