A method performed by a computing device , comprising as the computing device is moving within an environment of a playback device , capturing , via a microphone of the computing device, one or more calibration sounds played by the playback device, wherein each of the one or more calibration sounds includes: a first component that includes calibration noise at frequencies between a minimum of a calibration frequency range and a first threshold frequency ; and a second component that sweeps through frequencies between a second threshold frequency and a maximum of the calibration frequency range, wherein the second threshold frequency is lower than the first threshold frequency, and the first threshold frequency is lower than the maximum of the calibration frequency range; generating data representing the one or more calibration sounds; identifying one or more sections of the data such that each of the one or more sections of the data corresponds to a respective calibration sound of the one or more calibration sounds; using the one or more sections of the data to determine a frequency response of the playback device over the calibration frequency range, wherein the frequency response of the playback device characterizes audio playback by the playback device as influenced by acoustic characteristics of the environment of the playback device; determining one or more parameters of an audio processing algorithm based on the frequency response of the playback device and a target frequency response; and sending , to the playback device, the one or more parameters of the audio processing algorithm. as the computing device is moving within an environment of a playback device , capturing , via a microphone of the computing device, one or more calibration sounds played by the playback device, wherein each of the one or more calibration sounds includes: a first component that includes calibration noise at frequencies between a minimum of a calibration frequency range and a first threshold frequency ; and a second component that sweeps through frequencies between a second threshold frequency and a maximum of the calibration frequency range, wherein the second threshold frequency is lower than the first a first component that includes calibration noise at frequencies between a minimum of a calibration frequency range and a first threshold frequency ; and a second component that sweeps through frequencies between a second threshold frequency and a maximum of the calibration frequency range, wherein the second threshold frequency is lower than the first threshold frequency, and the first threshold frequency is lower than the maximum of the calibration frequency range; generating data representing the one or more calibration sounds; identifying one or more sections of the data such that each of the one or more sections of the data corresponds to a respective calibration sound of the one or more calibration sounds; using the one or more sections of the data to determine a frequency response of the playback device over the calibration frequency range, wherein the frequency response of the playback device characterizes audio playback by the playback device as influenced by acoustic characteristics of the environment of the playback device; determining one or more parameters of an audio processing algorithm based on the frequency response of the playback device and a target frequency response; and sending , to the playback device, the one or more parameters of the audio processing algorithm. <EOS>
