APPARATUS AND METHOD FOR SCREEN RELATED AUDIO OBJECT REMAPPING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240265930 titled 'APPARATUS AND METHOD FOR SCREEN RELATED AUDIO OBJECT REMAPPING

The patent application describes an apparatus for generating loudspeaker signals based on audio objects and their positions, as indicated in metadata.

• Object metadata processor calculates the position of the audio object based on screen size if it is screen-related, and feeds this information to the object renderer.
• If the audio object is not screen-related, the processor feeds the original position information to the object renderer.
• Object renderer generates loudspeaker signals based on the audio object and position information.

Potential Applications: - Surround sound systems - Virtual reality and augmented reality applications - Gaming consoles and immersive audio experiences

Problems Solved: - Precise positioning of audio objects in a 3D space - Enhancing the immersive audio experience for users

Benefits: - Improved audio localization - Enhanced realism in audio playback - Customizable audio experiences based on object positions

Commercial Applications: Title: "Enhanced Surround Sound Systems for Immersive Audio Experiences" This technology can be used in home entertainment systems, movie theaters, gaming setups, and virtual reality experiences to provide users with a more immersive and realistic audio experience.

Prior Art: Research existing patents related to audio object positioning and rendering in spatial audio systems to understand the current state of the technology.

Frequently Updated Research: Stay updated on advancements in spatial audio technology, object-based audio rendering, and immersive audio experiences to incorporate the latest innovations into the apparatus.

Questions about the technology: 1. How does the object metadata processor calculate the position of audio objects in relation to the screen size? 2. What are the key differences between screen-related and non-screen-related audio objects in terms of position calculation and rendering?

Original Abstract Submitted

an apparatus for generating loudspeaker signals includes an object metadata processor configured to receive metadata, to calculate a second position of the audio object depending on the first position of the audio object and on a size of a screen if the audio object is indicated in the metadata as being screen-related, to feed the first position of the audio object as the position information into the object renderer if the audio object is indicated in the metadata as being not screen-related, and to feed the second position of the audio object as the position information into the object renderer if the audio object is indicated in the metadata as being screen-related. the apparatus further includes an object renderer configured to receive an audio object and to generate the loudspeaker signals depending on the audio object and on position information.
