Abstract
Techniques described herein may involve dynamically adjusting the equalization of multiple speakers in a playback device. An example implementation involves a playback device emitting, via a first speaker, a first audio signal and emitting, via a second speaker, a second audio signal. The playback device may detect, via a microphone, an audio signal representing (i) at least a portion of the first audio signal and (ii) at least a portion of the second audio signal. The implementation may further involve the playback device determining one or more reflection characteristics based on the detected audio signal. The example implementation may also involve identifying a first audio setting and a second audio setting based on one or more reflection characteristics and applying (i) the first audio setting to playback of media content via the first speaker and (ii) the second audio setting to playback of media content via the second speaker.
