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,
wherein the audio data is for a plurality of audio elements,
wherein the plurality of audio elements corresponds to a plurality of audio sources in the scene,
wherein the plurality of audio elements comprises a first audio element,
a first renderer circuit, wherein the first renderer circuit is arranged to render audio elements by generating a first plurality of audio signals,
wherein the first plurality of audio signals are for a plurality of loudspeakers;
a second renderer circuit, wherein the second renderer circuit is arranged to render audio elements by generating a second plurality of audio signals,
wherein the second plurality of audio signals are for headphones; and
a selector circuit,
wherein the selector circuit is arranged to perform an analysis of the first audio element so as to determine an audio property of the first audio element as a result of the analysis,
wherein the selector circuit is arranged to select, based on the audio property, between the first renderer circuit, for rendering at least a first part of the first audio element via the plurality of loudspeakers, and the second renderer circuit, for rendering the first part of the first audio element via the headphones,
wherein the selector circuit is arranged to select between the first renderer circuit and the second renderer circuit for the first part 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 part of the first audio element.
