Abstract
An apparatus for generating a sound field description from an input signal having one or more channels including: an input signal analyzer for obtaining diffuseness data from the input signal; a sound component generator for generating, from the input signal, one or more sound field components of a first group of sound field components having for each sound field component a direct component and a diffuse component, and for generating, from the input signal, a second group of sound field components having only a direct component, the sound component generator being configured to perform an energy compensation when generating the first group of sound field components, the energy compensation depending on the diffuseness data and a number of sound field components in the second group, a number of diffuse components in the first group, or a maximum order of sound field components.
