Claim 27:
28. A non-transitory digital storage medium having a computer program stored thereon to perform the method for reproducing a spatially extended sound source comprising a defined position and geometry in a space, the method comprising:
receiving a listener position;
calculating a projection of a two-dimensional or three-dimensional hull associated with the spatially extended sound source onto a projection plane using the listener position, information on the geometry of the spatially extended sound source, and information on the position of the spatially extended sound source;
calculating positions of at least two sound sources for the spatially extended sound source using the projection plane; and
rendering the at least two sound sources at the positions to acquire a reproduction of the spatially extended sound source comprising two or more output signals, wherein the rendering comprises using different sound signals for the different positions, wherein the different sound signals are associated with the spatially extended sound source,
when said computer program is run by a computer.
