Calibration using multiple recording devices
First Claim
1. A system comprising:
- a playback device comprising a network interface, one or more speakers, a microphone, one or more processors, and data storage having stored therein instructions executable by the one or more processors to cause the playback device to perform functions comprising;
emitting, via the one or more speakers of the playback device, calibration audio during a calibration sequence, wherein the calibration sequence involves the playback device remaining stationary within a given environment while emitting the calibration audio;
detecting, via the microphone of the playback device, at least a portion of the calibration audio as emitted by the playback device during the calibration sequence; and
sending, via the network interface of the playback device, data representing a first response indicating an acoustic response of the given environment to the calibration audio as detected by the microphone of the playback device; and
a mobile device comprising a network interface, a microphone, one or more processors, and data storage having stored therein instructions executable by the one or more processors to cause the mobile device to perform functions comprising;
during the calibration sequence, detecting, via the microphone of the mobile device, at least a portion of the calibration audio as emitted by the playback device;
determining a second response, the second response indicating an acoustic response of the given environment to the calibration audio as detected by the microphone of the mobile device;
receiving, via the network interface of the mobile device, data indicating the first response;
determining a calibration for the playback device based on the first response and the second response, wherein determining the calibration for the playback device comprises normalizing the second response relative to the first response; and
sending, via the network interface of the mobile device, an instruction that applies the determined calibration to playback by the playback device.

Abstract
Example techniques may involve calibration with multiple recording devices. An implementation may include detecting, via a microphone, one or more calibration sounds as emitted by one or more playback devices of one or more zones during a calibration sequence. The implementation may further include determining a first response, the first response representing a response of a given environment to the one or more calibration sounds as detected by the first recording device and receiving data indicating a second response, the second response representing a response of the given environment to the one or more calibration sounds as detected by a second recording device. The implementation may also include determining a calibration for the one or more playback devices based on the first response and the second response and sending, to the one or more zones, an instruction that applies the calibration to playback by the one or more playback devices.
