Playback device calibration

Abstract:

Examples described herein involve calibrating one or more playback devices. An example implementation involves a mobile device receiving data representing an audio signal recorded via a microphone at multiple locations between a first physical location and a second physical location within a given environment while one or more playback devices played back calibration audio within the given environment. Based on the received data representing the audio signal, the mobile device determines acoustic characteristics of the given environment. Based on the determined acoustic characteristics of the given environment, the mobile device determines one or more audio processing algorithms to adjust audio output of the one or more playback devices in the given environment to have a pre-determined audio characteristic and causes, via a network interface, the one or more playback devices to apply the determined one or more audio processing algorithms to playback of audio content.
