Abstract
An example computing device is configured to perform functions including receiving a plurality of spectral data associated with a respective plurality of playback environments corresponding to a respective plurality of playback devices. The functions also include, based on the plurality of spectral data, determining a plurality of representative spectral characteristics. The functions also include receiving particular spectral data associated with a particular playback environment corresponding to a particular playback device and identifying a given one of the representative spectral characteristics that is representative of the particular spectral data. The functions also include, based on the given one of the representative spectral characteristics, identifying calibration data for use by the particular playback device when playing back audio and transmitting, to the particular playback device, the calibration data.
