Playback device calibration based on representative spectral characteristics

A system comprising:

• a computing device comprising a microphone;
• at least one processor;
• and
• at least one non-transitory computer-readable medium comprising program instructions that are executable by the at least one processor such that the system is configured to:
• during playback of audio content by a playback device via at least one audio transducer in an environment, capture, via the microphone, microphone data representing at least a portion of the audio content played back by the playback device, wherein the microphone data:
• (1) includes audio in a first sub-range of a frequency range and a second sub-range of the frequency range and (2) excludes audio in one or more third sub-ranges of the frequency range, wherein the at least one audio transducer of the playback device is configured to reproduce audio over at least the frequency range;
• determine spectral data based on portions of the captured microphone data in the first sub-range of the frequency range;
• identify a stored audio processing algorithm corresponding to the determined spectral data, the identified audio processing algorithm at least partially offsetting acoustic characteristics of the environment across the frequency range, wherein the acoustic characteristics of the environment comprise at least one first acoustic characteristic within the second sub-range and at least one second acoustic characteristic within the one or more third sub-ranges;
• and
• calibrate the playback device with the identified audio processing algorithm.
