==SYSTEM AND METHOD FOR ADAPTIVE AUDIO SIGNAL GENERATION, CODING AND RENDERING - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240349010 titled 'SYSTEM AND METHOD FOR ADAPTIVE AUDIO SIGNAL GENERATION, CODING AND RENDERING

The abstract describes an adaptive audio system that processes audio data with independent monophonic audio streams, some of which are channel-based and others are object-based.

* Channel-based streams have rendering information encoded by channel name, while object-based streams have location information encoded through location expressions in the metadata.
* A codec packages the audio streams into a single serial bitstream for rendering sound according to an allocentric frame of reference based on the playback environment characteristics.
* The object position metadata contains the necessary allocentric frame of reference information for correct sound playback using available speaker positions in a room set up for adaptive audio content.

Potential Applications:
- Immersive audio experiences in virtual reality environments
- Enhanced audio rendering in gaming and entertainment systems
- Spatial audio for augmented reality applications

Problems Solved:
- Providing accurate sound positioning in various playback environments
- Enhancing the realism and immersion of audio content
- Simplifying the rendering process for complex audio streams

Benefits:
- Improved audio quality and spatial accuracy
- Enhanced user experience in audio-rich environments
- Increased flexibility in audio production and playback

Commercial Applications:
Title: "Innovative Adaptive Audio System for Enhanced Sound Rendering"
This technology can be utilized in:
- Virtual reality and augmented reality systems
- Gaming consoles and entertainment platforms
- Audio production studios and post-production facilities

Questions about the technology:
1. How does the adaptive audio system differentiate between channel-based and object-based audio streams?
2. What are the key advantages of using an allocentric frame of reference for sound rendering in various playback environments?


==Original Abstract Submitted==

embodiments are described for an adaptive audio system that processes audio data comprising a number of independent monophonic audio streams. one or more of the streams has associated with it metadata that specifies whether the stream is a channel-based or object-based stream. channel-based streams have rendering information encoded by means of channel name; and the object-based streams have location information encoded through location expressions encoded in the associated metadata. a codec packages the independent audio streams into a single serial bitstream that contains all of the audio data. this configuration allows for the sound to be rendered according to an allocentric frame of reference, in which the rendering location of a sound is based on the characteristics of the playback environment (e.g., room size, shape, etc.) to correspond to the mixer's intent. the object position metadata contains the appropriate allocentric frame of reference information required to play the sound correctly using the available speaker positions in a room that is set up to play the adaptive audio content.
