Audio calibration of a portable playback device
First Claim
1. A playback device comprising:
- a microphone;
a speaker;
one or more processors;
an accelerometer configured to output data indicative of movement by the playback device; and
data storage storing instructions executable by the one or more processors to cause the playback device to perform operations comprising;
storing an acoustic response database comprising a plurality of sets of stored audio calibration settings, each set of stored audio calibration settings associated with a respective stored acoustic area response of a plurality of stored acoustic area responses;
determining that the playback device is to perform an equalization calibration of the playback device; and
in response to the determination that the playback device is to perform the equalization calibration, initiating the equalization calibration, wherein the equalization calibration comprises;
outputting, via the speaker, audio content;
capturing, via the microphone, audio data representing reflections of the audio content within an area in which the playback device is located;
based on at least the captured audio data, determining an acoustic response of the area in which the playback device is located;
selecting a stored acoustic response from the acoustic response database that is most similar to the determined acoustic response of the area in which the playback device is located; and
applying to the audio content, a set of stored audio calibration settings associated with the selected stored acoustic response.

Abstract
Disclosed herein are example techniques to facilitate calibrating a portable playback device. An example implementation involves determining that a playback device is to perform an equalization calibration of the playback device and initiating the equalization calibration. Initiating the equalization calibration involves (i) outputting audio content, (ii) capturing audio data representing reflections of the audio content within an area in which the playback device is located, (iii) determining an acoustic response of the area in which the playback device is located, (iv) selecting a stored acoustic response from the acoustic response database that is most similar to the determined acoustic response of the area in which the playback device is located, and (v) applying to the audio content, via the playback device, a set of stored audio calibration settings associated with the selected stored acoustic area response.
