Methods for determining relative locations of wireless loudspeakers

Methods, systems, and apparatuses are described for determining relative locations of wireless loudspeakers and performing channel mapping thereof. An 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.

Techniques for arranging stage elements on a stage

A stage arrangement system is configured to arrange stage elements on a stage where a performance is to take place. The stage arrangement system is configured to move the stage elements to reflect arrangement data that reflects desired positions and orientations for each stage element. The stage arrangement system first localizes one or more stage elements by determining the position and orientation associated with each such element. Then, the stage arrangement system repositions and/or reorients each stage element to comply with the arrangement data. Each stage element may indicate position and/or orientation changes to stagehands or manual laborers, who then move each element accordingly. Alternatively, each stage element may autonomously move in order to implement the position and/or orientation changes.
