What is MPEG-H 3D Audio?
MPEG-H 3D Audio is an advanced audio technology developed by the Moving Picture Experts Group (MPEG) that aims to provide a more immersive and realistic audio experience for users. It is designed to deliver high-quality audio with spatial and interactive capabilities, allowing listeners to feel like they are in the middle of the sound environment.
MPEG-H 3D Audio supports various audio formats, including object-based audio, channel-based audio, and higher-order ambisonics. This flexibility allows content creators to deliver audio that is tailored to the specific needs of their audience, whether they are listening through headphones, speakers, or a surround sound system.
How does MPEG-H 3D Audio work?
MPEG-H 3D Audio works by capturing and encoding audio in a way that preserves spatial information, allowing for a more immersive listening experience. This is achieved through the use of advanced audio processing techniques, such as sound field modeling, object-based audio rendering, and audio scene description.
Sound field modeling involves capturing the spatial characteristics of a sound environment, such as the direction and distance of sound sources, and encoding this information into the audio stream. Object-based audio rendering allows content creators to place sound objects in a 3D space and control their position, movement, and other properties in real-time. Audio scene description provides metadata that describes the audio content, allowing playback devices to optimize the audio experience based on the user’s preferences and playback environment.
