Abstract

Apparatus and method of implementing a dual-purpose sound system. In an embodiment, the apparatus comprises a first stage comprising a master volume controller configured to perform volume control of audio signals for audio channels of a sound system to generate variable-volume audio signals for the audio channels, and a second stage comprising an audio mixer configured to mix the variable-volume audio signals for a target set of the audio channels with fixed-volume ultrasonic signals for localization to generate at least two combined audio/ultrasonic signals configured for output to loudspeakers of the sound system corresponding with the target set of the audio channels.
