Playback device calibration based on representation spectral characteristics

A computing device comprising:

• a processor;
• a non-transitory computer readable medium;
• and
• program instructions stored on the non-transitory computer readable medium that, when executed by the processor, cause the computing device to perform functions comprising:
• maintaining a database of representative spectral characteristics;
• receiving particular spectral data associated with a particular playback environment corresponding to a particular playback device;
• based on the particular spectral data, identifying one of the representative spectral characteristics from the database that substantially matches the particular spectral data;
• identifying, in the database, an audio processing algorithm based on a) the identified representative spectral characteristic and b) at least one characteristic of the particular playback device;
• and
• transmitting, to the particular playback device, data indicating the identified audio processing algorithm.

A playback device comprising:

• a processor;
• a microphone;
• a non-transitory computer readable medium;
• and
• program instructions stored on the non-transitory computer readable medium that, when executed by the processor, cause the playback device to perform functions comprising:
• playing back first audio content in a playback environment;
• recording, via the microphone, at least a portion of the played back first audio content;
• while recording the played back first audio content, transmitting the recorded audio content to a computing device;
• receiving, from the computing device, an indication that no further recorded audio content is required;
• based on the indication that no further recorded audio content is required, discontinuing recording the played back first audio content;
• receiving, from the computing device, data indicating an audio processing algorithm corresponding to the playback environment;
• and
• applying the audio processing algorithm while playing back second audio content in the playback environment.
