Abstract: Methods, systems, and apparatuses are described for determining relative locations of wireless loudspeakers and performing channel mapping thereof Δn audio processing component utilizes sounds produced by wireless loudspeakers during setup/installation procedures, which are received by a microphone at locations in an acoustic space, to determine an amount of time between when the audio signal is initially transmitted and when the microphone signal is received. The audio processing component also utilizes wireless timing signals provided by a wireless transceiver, at locations in the acoustic space, to wireless loudspeakers and then back to the wireless transceiver to determine an amount of time between transmission and reception by the wireless transceiver. The timing delays are used to determine the locations of the wireless loudspeakers in the acoustic space. Based on the determined locations, the audio processing component generates indications of correct or incorrect wireless loudspeaker placements, and performs audio channel mapping.
