System and method for loudspeaker position estimation

An apparatus comprising:

• a first microphone, wherein the first microphone is configured to generate a first audio signal in response to a loudspeaker outputting a test signal;
• a second microphone, wherein the second microphone is configured to generate a second audio signal in response to the loudspeaker outputting the test signal;
• and
• a computing system coupled to at least one of the first microphone or the second microphone, the computing system comprising a processor configured to execute computer-executable instructions that, when executed, cause the computing system to:
• determine a time difference of arrival estimate based on the first audio signal and the second audio signal;
• determine a first angle based on the time difference of arrival estimate;
• determine a second angle using the first audio signal and the second audio signal;
• and
• resolve an abnormal condition corresponding to the loudspeaker indicated by at least one of the first angle or the second angle.

A method comprising:

• receiving a first audio signal from a first microphone and a second audio signal from a second microphone;
• determining a time difference of arrival estimate based on the first audio signal and the second audio signal;
• determining a first angle based on the time difference of arrival estimate;
• determining a second angle using the first audio signal and the second audio signal;
• and
• resolving an abnormal condition corresponding to the loudspeaker indicated by at least one of the first angle or the second angle.

Non-transitory physical computer storage comprising executable instructions stored thereon that, when executed by a hardware processor, are configured to at least:

• instruct a loudspeaker to transmit a test signal;
• determine a first angle based on a first audio signal recorded from a first microphone and a second audio signal recorded from a second microphone using a first technique;
• determine a second angle based on the first audio signal and the second audio signal using a second technique;
• and
• resolve a configuration error corresponding to the loudspeaker indicated by at least one of the first angle or the second angle.
