RENDERING ENCODED 6DOF AUDIO BITSTREAM AND LATE UPDATES

Examples of the disclosure relate to apparatus, methods and computer programs for enabling audio content rendering. An example apparatus comprising means for receiving a bitstream which comprises audio content; means for receiving dynamic content independent from the bitstream; means for receiving at least one instruction for the dynamic content from at least one of: the received bitstream or the received dynamic content; and means for rendering audio with a renderer based upon the audio content of the bitstream, the received dynamic content, and the at least one instruction. In an embodiment, the means for receiving the at least one instruction comprises means for determining presence the of at least one instruction for the dynamic content in the bitstream, When the bitstream does not comprise the at least one instruction for the received dynamic content, the apparatus comprising means for rendering audio with a renderer based upon the audio content of the bitstream without adapting the audio based upon the received dynamic content, When the bitstream comprises the at least one instruction for the received dynamic content, the apparatus comprising means for rendering the audio with the renderer based upon the audio content of the bitstream, the received dynamic content, and the at least one instruction. In a further embodiment, the apparatus further comprising means for determining position of audio elements in the audio scene and audio elements in the dynamic content. When the audio elements in the audio scene and the audio elements in the dynamic content are in a same acoustic environment, the apparatus comprising means for rendering audio with the renderer based upon the audio content of the bitstream without adapting the audio based upon the received dynamic content. When the audio elements in the audio scene and the audio elements in the dynamic content are not in the same acoustic environment, the apparatus comprising means for rendering the audio with the renderer based upon both the audio content of the bitstream and the received dynamic content. In an embodiment, the apparatus further comprising means for determining an anchor object in an audio scene; means for determining at least one instruction for dynamic content relative to the anchor object; and means for transmitting the audio scene in a bitstream, where the bitstream comprises the at least one instruction.
