Apparatus, system and/or method for noise time-frequency masking based direction of arrival estimation for loudspeaker audio calibration

An audio system comprising:

• a first loudspeaker including:
• memory;
• and
• at least one controller programmed to receive an audio signal including audio data and a signature tone from a second loudspeaker:
• store the audio signal including the signature tone in the memory;
• determine a direction of arrival (DOA) of the audio signal based at least on the signature tone;
• and
• perform a time frequency masking operation on the received audio signal prior to determining the DOA of the audio signal.

A computer-program product embodied in a non-transitory computer readable medium that is stored in memory and that is programmed and executable by at least one controller in an audio system, the computer-program product comprising instructions to:

• receive, at a first loudspeaker, an audio signal from a second loudspeaker, the audio signal including audio data and a signature tone;
• determine a direction of arrival (DOA) of the audio signal as received at the first loudspeaker based at least on the signature tone;
• and
• perform a time frequency masking operation on the received audio signal prior to determining the DOA of the audio signal.
