Claim 25:
26. The apparatus of claim 1, configured for
receiving a bitstream representing a compressed description for the spatially extended sound source, the bitstream comprising a bitstream element indicating a first number of different sound signals for the spatially extended sound source comprised by the bitstream or an encoded audio signal received by the apparatus, the number being one or greater than one,
reading the bitstream element and retrieving the first number of different sound signals for the spatially extended sound source comprised by the bitstream or in the encoded audio signal, and
wherein the sound position calculator determines a second number of sound sources used for the rendering of the spatially extended sound source, the second number being greater than one, and
wherein the renderer is configured to generate, depending on the first number extracted from the bitstream, a third number of one or more decorrelated signals, the third number being derived from a difference between the second number and the third number.
