Abstract
An interface for balancing speaker sound for use in consumer electronics and professional sound reinforcement field features a wireless speaker array. Optimization is accomplished by assigning the correct audio channel to each wireless speaker by a “chime” sound with multiple frequency components, and optimizing the sound of the speaker array by providing a wireless transmitter device with precise positions of each item for subsequent optimization of relative gain and delay for each speaker relative to the sweet spot.
