Original Abstract Submitted

example techniques facilitate calibration of a playback device. an example implementation involves a computing device capturing, via a microphone, data representing multiple iterations of a calibration sound as played by a playback device. the computing device identifies multiple sections within the captured data. two or more sections represent respective iterations of the calibration sound as played by the playback device. based on the multiple identified sections, the computing device determines a frequency response of the playback device, the frequency response of the playback device representing audio output by the playback device and acoustic characteristics of an environment around the playback device. based on the frequency response of the playback device and a target frequency response, the computing device determines one or more parameters of an audio processing algorithm and sends, to the playback device, the one or more parameters of the audio processing algorithm.
