Flat-panel audio displays use an array of force actuators to render sound sources on a display screen. The signal sent to each force actuator depends on the actuator position, the resonant properties of the panel, and the source position on the screen. A source may be translated to different spatial locations using the shifting theorem of the Fourier transform. A real-time implementation of this source positioning is presented using the MATLAB Audio Systems Toolbox. The implementation includes a graphical interface that allows a user to dynamically position the sound source on the screen. This implementation may be combined with audio source separation techniques to align audio sources with video images in real-time as part of a multimodal display.
