(54) Title: CONCEPT FOR GENERATING AN ENHANCED SOUND-FIELD DESCRIPTION OR A MODIFIED SOUND FIELD DESCRIPTION USING A MULTI-LAYER DESCRIPTION (57) : An apparatus for generating an enhanced sound field de- scription comprises: a sound field generator (100) for generating at least two sound field layer descriptions indicating sound fields with respect to at least one reference location; and a meta data generator (110) for gener- ating meta data relating to spatial information of the sound fields, where- in the sound field descriptions and the meta data constitute the enhanced sound field description. The meta data can be a geometrical information for each layer such as a representative distance to the reference location. 250 sound field generator for 1 s ` sound-field 120 combiner (output interface) 260 enhanced sound field description sound field generator for 2\"' sound-field 110 W O 20 19/0 12133 Al meta data generator (inform. on 1st 2nd sound-fields Fig. 2 [Continued on next page] WO 2019/012133 Al MIDEDIMOHNORMIENEHHOEMOMOVOIMIE Published: — with international search report (Art. 21(3))
