Abstract

A method and device are provided for determining a reproduction position of a source of sound for audio-visual reproduction of a film scene from a plurality of individual pictures with regard to a reproduction surface having a predetermined width, and with regard to a projection source having a projection reference point. A recording position of the source of sound, a camera position during recording, and an aperture angle of the camera during recording are obtained and the determined recording position is transformed to a camera coordinate system. A reproduction position for the source of sound is calculated and used to produce sound-source positioning in a reproduction room using wave-field synthesis methods.
