A METHOD AND APPARATUS FOR AR SCENE MODIFICATION

An apparatus for generating information to assist rendering an audio scene, the apparatus comprising means configured to: obtain at least one audio signal; obtain at least one scene parameter (415, 417) associated with the at least one audio signal, the at least one scene parameter (415, 417) being configured to define a position within the audio scene, wherein the audio scene is defined by the at least one audio signal and the at least one scene parameter (415, 417); obtain at least one anchor parameter (411, 413, 419) associated with the at least one audio signal, wherein the at least one anchor parameter (411, 413, 419) is associated with at least one listening space anchor (105, 107, 113, 401) located within a listening space (101) during rendering and the at least one anchor parameter (411, 413, 419) is configured to assist in mapping the position within the listening space (101), the listening space (101) being a virtual and/or physical space within which the audio scene is rendered, wherein the mapped position is scaled to fit within the listening space (101) and/ or the mapped position at least in part modifies the listening space (101); and generate a bitstream comprising the at least one audio signal, the at least one scene parameter (415, 417) and at least one anchor parameter (411, 413, 419).
