Apparatus, system and/or method for device localization and optimization utilizing a predetermined audible signal

An audio system comprising:

• a first loudspeaker including:
• memory;
• and
• at least one controller being operably coupled to the memory and being programmed to:
• transmit a first audio signal including a first signature tone into a listening environment;
• receive a second audio signal including a second signature tone from a second loudspeaker;
• receive the first audio signal including the first signature tone after transmitting the first audio signal into the listening environment;
• determine an estimated distance between the first loudspeaker and the second loudspeaker based at least on the first signature tone and the second signature tone;
• and
• perform a time frequency masking operation to extract at least one of the first signature tone from the first audio signal and the second signature tone from the second audio signal prior to determining the estimated distance between the first loudspeaker and the second loudspeaker.

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:

• transmit a second audio signal including a second signature tone into a listening environment via a second loudspeaker;
• receive a first audio signal including a first signature tone from a first loudspeaker;
• receive the second audio signal including the second signature tone after transmitting the second audio signal;
• determine an estimated distance between the first loudspeaker and the second loudspeaker based at least on the first signature tone and the second signature tone;
• and
• perform a time frequency masking operation to extract at least one of the first
• signature tone from the first audio signal and the second signature tone from the second audio signal prior to determining the estimated distance between the first loudspeaker and the second loudspeaker.
