Classification: CPC H | IPC H

Claim 9:
10. A system comprising:
a playback device comprising one or more audio transducers;
a network interface;
at least one microphone;
at least one processor; and
at least one non-transitory computer-readable medium storing instructions that are executable by the at least one processor such that the system is configured to:
while the playback device is at a first position in a first environment, output audio via the one or more audio transducers of the playback device;
during output of the audio, record, via the at least one microphone, the audio as outputted via one or more audio transducers;
based on the recorded audio, determine a self-response of the playback device in the first environment;
estimate a room response at a second position in the first environment, wherein the instructions that are executable by the at least one processor such that the playback device is configured to estimate the room response comprise instructions that are executable by the at least one processor such that the playback device is configured to apply a mapping to the determined self-response, wherein the mapping is based on multiple pre-determined room responses of additional playback devices that were determined in multiple second environments;
determine calibration settings that at least partially offset acoustic characteristics of the first environment as represented in the estimated room response; and
apply the determined calibration settings to playback by the playback device.
