Claim 0:
1. An audio apparatus, comprising:
a receiver circuit,
wherein the receiver circuit is arranged to receive data,
wherein the data describes an audio scene,
wherein the data comprises audio data and metadata,
wherein the audio data is for a set of audio elements corresponding to audio sources in the scene,
wherein the set of audio elements comprises a first audio element
wherein the metadata comprises at least a first audio rendering property indicator,
wherein the first audio rendering property indicator is for the first audio element;

a first renderer circuit, wherein the first renderer circuit is arranged to render audio elements by generating a first set of audio signals for a set of loudspeakers;
a second renderer circuit, wherein the second renderer circuit is arranged to render audio elements by generating a second set of audio signals for headphones; and
a selector circuit, wherein the selector circuit is arranged to select between the first renderer circuit and the second renderer circuit such that the rendering of at least a first portion of the first audio element is in response to the first audio rendering property indicator;
wherein the first audio rendering property indicator is indicative of whether the first portion of the first audio element should be rendered via the loudspeakers, or rendered via the headphones,
wherein the selector circuit is arranged to select between the first renderer circuit and the second renderer circuit for the first portion of the first audio element,
wherein the selector circuit is arranged to select between the first renderer circuit and the second renderer circuit for a second portion of the first audio element.
