METHOD AND SYSTEM FOR HANDLING GLOBAL TRANSITIONS BETWEEN LISTENING POSITIONS IN A VIRTUAL REALITY ENVIRONMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240031760 titled 'METHOD AND SYSTEM FOR HANDLING GLOBAL TRANSITIONS BETWEEN LISTENING POSITIONS IN A VIRTUAL REALITY ENVIRONMENT

Simplified Explanation

The abstract describes a method for rendering audio in a virtual reality environment. The method involves rendering an audio signal from an audio source in an audio scene, based on the position of a listener. It also includes determining when the listener moves from one audio scene to another, and applying a fade-out gain to the audio signal to create a modified audio signal. The modified audio signal is then rendered from the original source position around the listener's position.

• The method involves rendering audio signals in a virtual reality environment.
• The audio signals are based on the position of a listener and an audio source.
• The method includes determining when the listener moves between different audio scenes.
• A fade-out gain is applied to the audio signal to create a modified version.
• The modified audio signal is rendered from the original source position around the listener's position.

Potential applications of this technology:

• Virtual reality gaming: This method can enhance the audio experience in virtual reality games, providing realistic and immersive sound effects.
• Virtual reality simulations: It can be used in training simulations, such as flight simulators or medical simulations, to create a more realistic audio environment.
• Virtual reality storytelling: This method can be used in virtual reality storytelling experiences to create a more immersive and engaging audio narrative.

Problems solved by this technology:

• Immersive audio experience: This method solves the problem of providing realistic and immersive audio in virtual reality environments, enhancing the overall user experience.
• Seamless audio transition: It addresses the issue of smooth audio transition when the listener moves between different audio scenes, ensuring a seamless and uninterrupted audio experience.

Benefits of this technology:

• Enhanced immersion: The method provides a more immersive virtual reality experience by accurately rendering audio based on the listener's position.
• Realistic audio environment: It creates a realistic audio environment, improving the overall realism and authenticity of virtual reality simulations and games.
• Seamless audio transition: The method ensures a smooth and seamless transition between different audio scenes, avoiding any jarring or abrupt changes in the audio experience.

Original Abstract Submitted

a method () for rendering audio in a virtual reality rendering environment () is described. the method () comprises rendering () an origin audio signal of an origin audio source () of an origin audio scene () from an origin source position on a sphere () around a listening position () of a listener (). furthermore, the method () comprises determining () that the listener () moves from the listening position () within the origin audio scene () to a listening position () within a different destination audio scene (). in addition, the method () comprises applying () a fade-out gain to the origin audio signal to determine a modified origin audio signal, and rendering () the modified origin audio signal of the origin audio source () from the origin source position on the sphere () around the listening position ().
