Abstract
Embodiments described herein may involve dynamically adjusting the equalization of a playback device based on the environment in which the playback device is operating. One embodiment may involve emitting a first audio signal from a playback device, detecting, by the playback device, a second audio signal, where at least a portion of the second audio signal is a reflection of the first audio signal, in response to the detecting, determining one or more reflection characteristics, where each of the one or more reflection characteristics are based on at least the second audio signal, adjusting an equalization setting of the playback device based on the one or more reflection characteristics, and causing an audio track to play according to the adjusted equalization setting.
Claims20
A method comprising:
- emitting, by a playback device, a first audio signal;
- detecting, by the playback device, a second audio signal, wherein at least a portion of the second audio signal is a reflection of the first audio signal;
- in response to the detecting, determining one or more reflection characteristics, wherein each of the one or more reflection characteristics are based on at least the second audio signal;
- adjusting an equalization setting of the playback device based on the one or more reflection characteristics;
- and
- causing an audio track to play according to the adjusted equalization setting.
In a media playback system comprising a plurality of playback devices, wherein each playback device comprises a respective microphone and a respective speaker, a method comprising:
- receiving an indication of a first audio signal;
- detecting, by a microphone of the first playback device, a second audio signal, wherein at least a portion of the second audio signal is indicative of the first audio signal;
- in response to the detecting, determining a first reflection characteristic based on the second audio signal;
- adjusting an equalization setting of the first playback device based on at least the first reflection characteristic;
- and
- sending to a second playback device an indication of the first reflection characteristic.
A playback device, comprising:
- a speaker;
- a microphone that is physically coupled to the speaker;
- a processor;
- a network interface;
- a data storage;
- and
- a program logic stored in the data storage and executable by the processor to:
- emit a first audio signal from the speaker;
- detect, via the microphone, a second audio signal, wherein at least a portion of the second audio signal is a reflection of the first audio signal;
- in response to the detecting, determine a first reflection characteristic based on at least the second audio signal;
- adjust an equalization setting of the playback device based on at least the first reflection characteristic;
- and
- play, via the speaker, an audio track according to the equalization setting.
