1. A playback device, comprising:
- one or more processors;
one or more transducers configured to output sound;
one or more microphones;
memory comprising instructions that, when executed by the one or more processors, cause the playback device to perform functions comprising;
performing a first test, wherein performing the first test comprises;
playing back, via the one or more transducers, a first test sound;
recording, via the one or more microphones, the first test sound, wherein the recorded first test sound comprises audio data in a range of frequencies; and
detecting, based on the recorded first test sound, data indicating a defect of the playback device based on the recorded first test sound, wherein the data indicating the defect comprises data in a subrange of frequencies of the range of frequencies having at least one of (i) missing spectral characteristics and (ii) deteriorated spectral playback characteristics with respect to an expected test sound;
based on the data indicating the defect of the playback device, performing a second test that is different than the first test, wherein performing the second test comprises;
playing back, via the one or more transducers, a second test sound comprising only audio within the subrange of frequencies;
recording, via the one or more microphones, the second test sound; and
determining details on the defect of the playback device based on the recorded second test sound.

16. A non-transitory computer-readable medium storing instructions that when executed by a playback device cause the playback device to perform functions comprising:
-
performing a first test, wherein performing the first test comprises; playing back a first test sound during a first time period; recording, via one or more microphones of the playback device, the first test sound, wherein the recorded first test sound comprises audio data in a range of frequencies; and detecting, based on the recorded first test sound, data indicating a defect of the playback device based on the recorded first test sound, wherein the data indicating the defect comprises data in a subrange of frequencies of the range of frequencies having at least one of (i) missing spectral characteristics and (ii) deteriorated spectral playback characteristics with respect to an expected test sound; based on the data indicating the defect of the playback device, performing a second test that is different than the first test, wherein performing the second test comprises; playing back, via the one or more transducers, a second test sound during a second time period, wherein the second test sound comprises only audio within the subrange of frequencies; recording, via the one or more microphones, the second test sound; and determining details on the defect of the playback device based on the recorded second test sound. - View Dependent Claims (17, 18, 19, 20)
