Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies have not adequately addressed the challenge of rendering spatial audio in a manner that allows for a high fidelity spatial experience, particularly in the rendering of audio objects in a manner that allows for a high fidelity spatial experience, and the lack of flexibility in existing technologies has resulted in suboptimal rendering of audio due to the requirement of speaker arrays that are not limited to the requirement of speaker arrays that are not limited to the requirement of speaker arrays that are not limited to the requirement of spatial arrays that are not limited to the requirement of spatial arrays that are not limited to the requirement of speaker arrays that must be arranged in a particular orientation with respect to the ideal listener location.
Innovation Solution
The systems and methods described herein utilize spatialization shaders to generate spatial audio rendering using a plurality of loudspeakers, each equipped with drivers, processors, and memory, which calculate tuning parameters based on the position and rotation of each loudspeaker to render audio stems at their respective locations, employing parameters like source focus, delay, and gain to achieve high fidelity spatial audio reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If speaker arrays are arranged in a particular orientation with respect to the ideal listener location to achieve high fidelity spatial audio, then audio rendering quality is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The system dynamically calculates tuning parameters for each loudspeaker based on its actual position and rotation in the environment. This allows the audio rendering to adapt to the physical arrangement of speakers rather than requiring a fixed ideal configuration, resolving the contradiction between rendering quality and configuration complexity
Solution Approach 2:
The patent changes the parameters of audio rendering by calculating individual tuning parameters (delay, gain, pan) for each loudspeaker based on its spatial characteristics. This parameter adaptation allows high fidelity spatial audio to be achieved regardless of the physical arrangement of speakers, eliminating the need for precise pre-configured speaker orientations
2Manufacturing precision
If a large number of speakers are used to create immersive spatial audio formats, then spatial audio quality is improved, but ease of operation and setup difficulty worsen
Solution Approach 1:
The system automatically determines the position and rotation of each loudspeaker in the environment and self-configures the audio rendering parameters accordingly. This self-service approach eliminates the need for manual configuration of speaker arrangements, making it easy to operate even with large numbers of speakers
Solution Approach 2:
The audio rendering system dynamically adapts to the actual physical arrangement of speakers by calculating individual tuning parameters for each device. This dynamic adaptation allows immersive spatial audio to be achieved with any speaker configuration, improving ease of operation while maintaining high spatial audio quality
3Manufacturing precision
If speakers are placed in prescribed locations to achieve optimal audio rendering, then audio fidelity is improved, but adaptability to different environments worsens
Solution Approach 1:
The system changes the audio rendering parameters based on the actual position and rotation of each loudspeaker detected in the environment. This parameter adaptation allows the system to maintain high audio fidelity across different environments without requiring speakers to be placed in prescribed locations
Solution Approach 2:
The audio rendering is made dynamic by continuously calculating tuning parameters based on the actual spatial configuration of speakers. This dynamic approach enables the system to adapt to different environmental arrangements while maintaining audio fidelity, resolving the contradiction between precision and adaptability
4Manufacturing precision
If channel-based surround sound audio is rendered using a large speaker array, then spatial audio quality is improved, but device complexity increases
Solution Approach 1:
The system dynamically calculates individual tuning parameters for each loudspeaker based on its position and rotation. This dynamic parameter calculation enables high-quality spatial audio rendering using any number of speakers, reducing the perceived complexity by automatically adapting the rendering to the actual hardware configuration
