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 speaker, a first audio signal. While emitting the first audio signal, the playback device detects, via a microphone, data representing a second audio signal, the second audio signal comprising one or more reflections of the first audio signal as emitted by the speaker within a surrounding environment. The playback device determines a frequency response curve based on the second audio signal, the frequency response curve representing acoustic characteristics of a system comprising the playback device and the surrounding environment. The playback device determines filter coefficients based on a difference between the determined frequency response curve and a target frequency response curve, and applies the filter coefficients to one or more filters during playback of audio content by the playback device.
