Increasing the interactive human involvement in the process control is one of the trends in developing modern multimedia systems. Using active stereo and controlling the stereo sound system in a listening area in real time is an understudied field at the present moment. The Microsoft Native Interaction technology enables detecting the human body in the area, capturing and tracking his movements.
The OpenNI algorithm converts human movements into a series of three-dimensional coordinates. These data can be used as a control signal, which makes adjustments to the phase-frequency and amplitude-frequency properties of the audio signal for each loudspeaker channel. That greatly enhances stereo playback capabilities in modern computer games, listening to music or watching videos.
The structural diagram of the sound pressure automated control system, amplitude-frequency and phase-frequency properties in the stereo loudspeaker system is proposed. It amplifies the perception of the phantom image, which is emitted from loudspeakers, enhances the interactive human presence effect.References
