Abstract:
Examples involve calibration of a synchronous playback group. In an example implementation, a first playback device forms a synchronous playback group with a second playback device. While part of the synchronous playback group, the first playback device receives a command to repeatedly emit a calibration sound according to a sequence for duration of time. Based on the command, the first playback device emits the calibration sound contemporaneously with emission of the calibration sound by the second playback device. Emission of the calibration sound by the first playback device and emission of the calibration sound by the second playback device are staggered such that each emitted calibration sound is delayed relative to a preceding emitted calibration sound. After the duration of time, the first playback device receives data indicating audio processing coefficients and applies the audio processing coefficients when playing back audio content in the synchronous playback group.

Claim (Index 3):
The first playback device of  claim 1 , wherein the calibration sound comprises (i) a first component that includes noise frequencies between a minimum of the calibration frequency range and a first threshold frequency, and (ii) a second component that sweeps through frequencies between a second threshold frequency and a maximum of the calibration frequency range.
