Abstract
Systems and methods are provided for device playback calibration. In one example, a calibration device with a microphone and signal processor may detect audio content rendered by a playback device. The calibration device may transmit the detected audio content to a processing unit configured to determine an equalization setting for optimal playback of the playback device based on the received detected audio content and a relative distance and direction between the playback device and the calibration device. The calibration device may further be configured to modulate the detected audio content before transmitting the detected audio content to the processing unit to accommodate for a limited frequency range of the processing unit. In this case, the processing unit may demodulate the received signal prior to determining the equalization setting. The processing unit may then transmit the determined equalization setting to the playback device according to a wireless communication protocol.
