IAMF is used to provide Immersive Audio content for presentation on a wide range of devices in both streaming and offline applications. The term 3D audio signal means a representation of sound that incorporates additional information beyond traditional stereo or surround sound formats such as Ambisonics (Scene-based), Object-based audio and Channel-based audio (e.g., 3.1.2ch or 7.1.4ch). The term Immersive Audio (IA) means the combination of 3D audio signals recreating a sound experience close to that of a natural environment. This specification defines an immersive audio model and formats (IAMF) to provide an immersive audio experience to end-users. 10.2.5 Annex B-5: ChannelGroup Generation Rule.10.2.4 Annex B-4: Recon Gain Generation.10.2.3 Annex B-3: Channel Layout Generation Rule.10.2.1 Annex B-1: Down-mix parameter and Loudness.10.2 Annex B: Rules for Scalable Channel Audio (Normative).10.1 Annex A: ID Linking Scheme (Informative).8.4.1 Two Audio Elements with One Codec Config.8 IAMF Generation Process (Informative).7.3.2.4 Rendering a Scene-Based Audio Element to Headphones.7.3.2.3 Rendering a Channel-Based Audio Element to Headphones.7.3.2.2 Rendering a Scene-Based Audio Element to Loudspeakers.7.3.2.1.2 Configuring the EAR Direct Speakers Renderer.7.3.2.1.1 Rendering Without Demixing Info.7.3.2.1 Rendering a Channel-Based Audio Element to Loudspeakers.7.2 Scalable Channel Audio Decoding and Reconstruction. ![]()
