Abstract
System, method and device to provide apparent audio source position of a performer on a stage using a monophonic wireless microphone and volume modulation of left and right audio channels based on the actual position of the performer. Two audio channels are produced using a single audio input channel plus position information. Performances are enhanced by the perception of the audience that the source of the sound, such as singing, is the location of the performer on the stage. Other embodiments use additional audio channels. One embodiment uses the carrier amplitude of the wireless microphone to determine position. In another embodiment two or more wireless microphone receivers are used to improve position accuracy. The stage may be real, virtual or remote. The performance and/or audio may be live or recorded. Calibration and adjustment features are included in alternate embodiments. Constant power panning is included in one embodiment.
