Calibration of a playback device based on an estimated frequency response

Abstract:

A first stream and second stream of audio are received. The first stream of audio may comprise source audio content to be played back by the audio playback device. The second stream of audio may comprise a recording of an audio signal output by the audio playback device based on the audio playback device playing the source audio content. An estimated frequency response of an audio playback device may be calculated based on the received first stream of audio and the received second stream of audio. Acoustics of the audio playback device may be adjusted based on the estimated frequency response.
