Abstract: An audio apparatus comprises a receiver (201) receiving data describing an audio scene. The data comprises audio data for a set of audio elements corresponding to audio sources in the scene and further includes metadata comprising at least an audio rendering property indicator for a first audio element of the set of audio elements. A first renderer (205) renders audio elements by generating a first set of audio signals for a set of loudspeakers and a second renderer (207) renders audio elements by generating a second set of audio signals for a headphone. Further, a selector (209) is arranged to select between the first renderer and the second renderer for rendering of at least a first part of the first audio element in response to the first audio rendering property indicator. The approach may for example provide improved virtual reality experiences using loudspeakers and headphone hybrid rendering.

Abstract: A distribution system comprises an audio server (101) for receiving incoming audio from remote clients (103) and for transmitting audio derived from the incoming audio to the remote clients (103). An audio apparatus comprises an audio a receiver (401) which receives data comprising: audio data for a plurality of audio components representing audio from a remote client of the plurality of remote clients; and proximity data for at least one of the audio components. The proximity data is indicative of proximity between remote clients. A generator (403) of the apparatus generates an audio mix from the audio components in response to the proximity data. For example, an audio component indicated to be proximal to a remote client may be excluded from an audio mix for that remote client.

Abstract: An audio apparatus, e.g. for rendering audio for a virtual/augmented reality application, comprises a receiver (201) for receiving audio data for an audio scene including a first audio component representing a real-world audio source present in an audio environment of a user. A determinator (203) determines a first property of a real-world audio component from the real-world audio source and a target processor (205) determines a target property for a combined audio component being a combination of the real-world audio component received by the user and rendered audio of the first audio component received by the user. An adjuster determines a render property by modifying a property of the first audio component indicated by the audio data for the first audio component in response to the target property and the first property. A renderer (209) renders the first audio component in response to the render property.

Abstract: An audio apparatus and method employ a first renderer circuit, wherein the first renderer circuit is arranged to render audio elements by generating a first plurality of audio signals for a plurality of loudspeakers; and a second renderer circuit, wherein the second renderer circuit is arranged to render audio elements by generating a second plurality of audio signals for headphones. The audio apparatus and method perform an analysis of the first audio element to determine an audio property of the first audio element, and select between rendering of at least a first part of the first audio element via the plurality of loudspeakers and rendering of at least the first part of the first audio element via the headphones, based on a result of the analysis.
