Abstract
An illustrative embodiment includes a method for use in performing acoustic calibration of at least one audio output device for a plurality of listening locations. An audio input device generates a data signal based on a series of one or more tones output by the at least one audio output device. The audio input device wirelessly transmits the data signal to a calibration device. The audio input device is one of a plurality of audio input devices deployed at respective ones of the plurality of listening locations. The data signal is one of a plurality of data signals generated by respective ones of the plurality of audio input devices based on the series of one or more tones output by the at least one audio output device. The plurality of data signals are wirelessly transmitted by the respective ones of the plurality of audio input devices to the calibration device.
