1. An apparatus for reproducing a spatially extended sound source comprising a defined position or orientation and geometry in a space, the apparatus comprising:
an interface configured for receiving a listener position;
a projector configured for 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;
a sound position calculator configured for calculating positions of at least two sound sources for the spatially extended sound source using the projection plane; and
a renderer configured for 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 renderer is configured to use different sound signals for the different positions, wherein the different sound signals are associated with the spatially extended sound source,
wherein the renderer is configured for rendering the at least two sound sources relative to a fixed location and/or orientation of the spatially extended sound source in response to a specific information received.
