1. A device comprising:
- at least one computer medium that is not a transitory signal and that comprises instructions executable by at least one processor to;
control at least a first light emitting diode (LED) associated with at least a first audio speaker assembly to communicate with at least a second audio speaker assembly using strobing wireless LED-based communication;
control the first LED to emit a detection signal detectable by at least one receiver outputting an indication of the detection to at least one processor for determining a location of at least a second audio speaker assembly in an enclosure in which the first audio speaker assembly is located;
determine plural time differences between respective times of receipt of plural received returns from respective return locations of respective detection signals, and respective transmission times of the respective detection signals;
correlate the plural time differences to corresponding distances;
determine that first ones of the plural received returns have amplitudes satisfying a threshold;
determine that second ones of the plural received returns have amplitudes not satisfying the threshold;
based at least in part on the first ones of the plural received returns having amplitudes satisfying the threshold, output a speaker assembly location based on at least one of the plural distances associated with the first ones of the plural received returns; and
based at least in part on the second ones of the plural received returns not having amplitudes satisfying the threshold, not output a speaker assembly location based on distances associated with the second ones of the plural received returns.

Abstract
A networked speaker system communicates using Li-Fi. The LEDs implementing the Li-Fi may also have modes in which they are used to map the walls of a room in which the speakers are located, detect the locations of speakers in the room, and detect and classify listeners in the room. Based on this, waveform analysis may be applied to input audio to establish equalization and delays that are optimal for the room geometry, speaker locations, and listener locations.
