Apparatus for processing a sound field representation related to a defined reference point or defined listening orientation for the sound field representation including: a sound field processor for processing the sound field representation using a deviation of a target listening position from the defined reference point or a target listening orientation from the defined listening orientation to obtain a processed sound field description which, when rendered, provides an impression of the sound field representation at the target listening position being different from the defined reference point or for the target listening orientation being different from the defined listening orientation, or for processing the sound field representation using a spatial filter to obtain the processed sound field description which, when rendered, provides an impression of a spatially filtered sound field description, the sound field processor being configured to process the sound field representation to apply the deviation or the spatial filter in a spatial transform domain with an associated forward transform rule and backward transform rule.

Apparatus, method or computer program for processing a sound field representation in a spatial transform domain

An apparatus for generating an enhanced sound field description includes: a sound field generator for generating at least one sound field description indicating a sound field with respect to at least one reference location; and a meta data generator for generating meta data relating to spatial information of the sound field, wherein the at least one sound field description and the meta data constitute the enhanced sound field description. The meta data can be a depth map associating a distance information to a direction in a full band or a subband, i.e., a time frequency bin.

Concept for generating an enhanced sound-field description or a modified sound field description using a depth-extended DirAC technique or other techniques
