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 8):
A method to be performed by a network microphone device (NMD), the method comprising:\n recording, via a microphone of the NMD, calibration audio emitted via multiple audio drivers of one or more playback devices, wherein the multiple audio drivers are configured to form a plurality of sound axes including a first sound axis and a second sound axis, and wherein individual sound axes correspond to a respective channel of multi-channel audio content, wherein the NMD is communicatively coupled with a media playback system that includes the one or more playback devices; arranging the recorded calibration audio into constituent frames including a first frame having a first slot and at least a second slot, wherein the first and second slots comprise respective portions of the recorded calibration audio corresponding to the first sound axis and the second sound axis; determining a first arrival time and a second arrival time of the respective portions of the recorded calibration audio in the first and second slots; determining a first delay for the first sound axis and a second delay for the second sound axis, wherein the first and second delays are based on the respective first and second arrival times; and causing, via a network interface, audio output of the first sound axis and the second sound axis to be delayed according to the respective first and second delays.
