Abstract
An apparatus for generating a sound field description using an input signal having a mono-signal or a multi-channel signal includes: an input signal analyzer for analyzing the input signal to derive direction data and diffuseness data; a low-order components generator for generating a low-order sound field description from the input signal up to a predetermined order and mode; a mid-order components generator for generating a mid-order sound field description above the predetermined order or at the predetermined order and above the predetermined mode and below or at a high order, wherein the mid-order sound field description comprises a direct contribution and a diffuse contribution; and a high-order components generator for generating a high-order sound field description comprising a sound field component above the high order using a synthesis of at least one direct portion, wherein the high-order sound field description comprises a direct contribution only.
