Audio processing algorithms
First Claim
1. A tangible non-transitory computer-readable medium having stored thereon instructions executable by a computing device to perform functions comprising:
- transmitting, via a local area network, a command that instructs a group of two or more playback devices to play a particular audio signal in a playback environment, wherein the group of two or more playback devices excludes the computing device;
receiving data representing an audio signal detected via one or more microphones, wherein the detected audio signal comprises a portion of the particular audio signal played via the group of two or more playback devices;
determining an acoustic characteristic of the playback environment based on the detected audio signal and respective acoustic characteristics of the two or more playback devices;
determining an audio processing algorithm based on the determined acoustic characteristic of the playback environment and a predetermined audio characteristic; and
causing at least one playback device of the group of two or more playback devices to apply the determined audio processing algorithm when playing audio as part of the group of two or more playback devices.

Abstract
An example implementation involves a computing device transmitting, via a local area network, a command that instructs a playback device to play a particular audio signal. The example implementation also involves the computing device receiving data indicating a detected audio signal corresponding to playback of the particular audio signal by the playback device, where the detected audio signal includes a portion of the particular audio signal. The implementation further involves the computing device obtaining data indicating a predetermined audio characteristic and determining an audio processing algorithm based on the detected audio signal and the predetermined audio characteristic. The example implementation involves causing the playback device to apply the determined audio processing algorithm when playing audio via at least one speaker.

9. A computing device comprising:
-
a processor; and memory having stored thereon instructions executable by the processor to cause the computing device to perform functions comprising; transmitting, via a local area network, a command that instructs a group of two or more playback devices to play a particular audio signal in a playback environment, wherein the group of two or more playback devices excludes the computing device; receiving data representing an audio signal detected via one or more microphones, wherein the detected audio signal comprises a portion of the particular audio signal played via the group of two or more playback devices; determining an acoustic characteristic of the playback environment based on the detected audio signal and respective acoustic characteristics of the two or more playback devices; determining an audio processing algorithm based on the determined acoustic characteristic of the playback environment and a predetermined audio characteristic; and causing at least one playback device of the group of two or more playback devices to apply the determined audio processing algorithm when playing audio as part of the group of two or more playback devices. - View Dependent Claims (10, 11, 12, 19)

13. A method comprising:
-
transmitting, via a computing device over a local area network, a command that instructs a group of two or more playback devices to play a particular audio signal in a playback environment, wherein the group of two or more playback devices excludes the computing device; receiving, via the computing device, data representing an audio signal detected via one or more microphones, wherein the detected audio signal comprises a portion of the particular audio signal played via the group of two or more playback devices; determining an acoustic characteristic of the playback environment based on the detected audio signal and respective acoustic characteristics of the two or more playback devices; determining, by the computing device, an audio processing algorithm based on the determined acoustic characteristic of the playback environment and a predetermined audio characteristic; and causing, via the computing device, at least one playback device of the group of two or more playback devices to apply the determined audio processing algorithm when playing audio as part of the group of two or more playback devices. - View Dependent Claims (14, 15, 16, 17, 20)
