Method and apparatus for describing sound sources

摘要

The method involves describing the wideness of a non-point sound source based on generated parametric description of a sound source. The parametric description is linked with audio signals of the sound source. Multiple decorrelated point sound sources are assigned at different positions to the non-point sound source to define a presentation of the non-point sound source. Independent claims are also included for the following: (a) a method for decoding a presentation description of audio signals (b) an apparatus for performing a method.
