Calibration based on audio content type
Example techniques may involve multiple calibrations for a playback device. In an example implementation, a first playback device, while playing back a first type of audio content via the one or more audio amplifiers configured to drive one or more speakers, applies a first calibration that offsets acoustic characteristics of a given environment when applied to playback by the first playback device. While playing back a second type of audio content via the one or more audio amplifiers configured to drive one or more speakers, the first playback device applies a second calibration that offsets acoustic characteristics of the given environment when applied to playback by the first playback device and calibrates the first playback device to one or more particular locations within the given environment.
1. A first playback device comprising:
one or more audio amplifiers configured to drive one or more speakers;
one or more processors; and
tangible, computer-readable media having instructions encoded therein, wherein the instructions, when executed by the one or more processors, cause the first playback device to perform a method comprising:
while playing back a first type of audio content via the one or more audio amplifiers configured to drive the one or more speakers, applying a first calibration to playback by the first playback device, the first calibration offsetting acoustic characteristics of a given environment; and
while playing back a second type of audio content via the one or more audio amplifiers configured to drive the one or more speakers, applying a second calibration to playback by the first playback device, the second calibration offsetting acoustic characteristics of the given environment and calibrating the first playback device to one or more particular locations within the given environment.

6. The first playback device of claim 1 , wherein the second calibration calibrating the first playback device to one or more particular locations within the given environment comprises one or more of (i) offsetting propagation delay from the first playback device to the one or more particular locations, or (ii) adjusting gain of the first playback device based on a distance from the first playback device to the one or more particular locations.
7. The first playback device of claim 6 , wherein the first playback device is configured into a stereo pair with a second playback device, and wherein adjusting gain of the first playback device based on distance from the first playback device to the one or more particular locations comprises balancing gain of the stereo pair to the one or more particular locations.
8. A method to be performed by a first playback device comprising one or more audio amplifiers configured to drive one or more speakers, the method comprising:
while playing back a first type of audio content via the one or more audio amplifiers configured to drive the one or more speakers, applying a first calibration to playback by the first playback device, the first calibration offsetting acoustic characteristics of a given environment; and
while playing back a second type of audio content via the one or more audio amplifiers configured to drive the one or more speakers, applying a second calibration to playback by the first playback device, the second calibration offsetting acoustic characteristics of the given environment and calibrating the first playback device to one or more particular locations within the given environment.
9. The method of claim 8 ,
wherein playing back the first type of audio content comprises playing back streaming audio content from a network source; and
wherein playing back the second type of audio content comprises playing back an audio track of a video.
10. The method of claim 8 ,
wherein playing back the first type of audio content comprises playing back streaming audio content from a network source; and
wherein playing back the second type of audio content comprises playing back audio content via a input interface associated with video content.
11. The method of claim 10 , wherein the input interface associated with video content comprises one of (a) a TOS-LINK interface or (b) an HDMI interface.
12. The method of claim 8 ,
wherein playing back the first type of audio content comprises playing back the first type of audio content synchronously in a synchrony group with a second playback device, and
wherein playing back the second type of audio content comprises playing back the second type of audio content individually.
13. The method of claim 8 , wherein the second calibration calibrating the first playback device to one or more particular locations within the given environment comprises one or more of (i) offsetting propagation delay from the first playback device to the one or more particular locations, or (ii) adjusting gain of the first playback device based on a distance from the first playback device to the one or more particular locations.
14. The method of claim 13 , wherein the first playback device is configured into a stereo pair with a second playback device, and wherein adjusting gain of the first playback device based on distance from the first playback device to the one or more particular locations comprises balancing gain of the stereo pair to the one or more particular locations.
15. A non-transitory computer-readable medium having stored therein instructions executable by one or more processors to cause a first playback device to perform a method comprising:
while playing back a first type of audio content via one or more audio amplifiers configured to drive one or more speakers, applying a first calibration to playback by the first playback device, the first calibration offsetting acoustic characteristics of a given environment, wherein the first playback device comprises the one or more audio amplifiers; and
while playing back a second type of audio content via the one or more audio amplifiers configured to drive the one or more speakers, applying a second calibration to playback by the first playback device, the second calibration offsetting acoustic characteristics of the given environment and calibrating the first playback device to one or more particular locations within the given environment.
16. The non-transitory computer-readable medium of claim 15 ,
wherein playing back the first type of audio content comprises playing back streaming audio content from a network source; and
wherein playing back the second type of audio content comprises playing back an audio track of a video.
