Spatial audio processing emphasizing sound sources close to a focal distance

Abstract

A spatial audio processing apparatus comprises a receiver () for receiving audio scene data describing an audio scene comprising spatial audio components and associated position data. The audio components may be provided as audio objects. A distance unit () provides a position indication which includes a focus distance that is indicative of a distance from a reference position in the audio scene. An adapter () adapts a perceptual emphasis property, such as an audio level, frequency distribution, or degree of diffuseness, of a spatial audio component relative to at least one other spatial audio component of the audio scene in response to a difference measure reflecting a difference between the focus distance and a distance in the audio scene from the reference position to a position of the spatial audio component. An audio renderer () renders the resulting audio scene using the received position data. The approach may emphasize audio at the focus distance in the audio scene.
