SYSTEMS AND METHODS FOR EFFICIENT AND ACCURATE VIRTUAL ACCOUSTIC RENDERING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240292171 titled 'SYSTEMS AND METHODS FOR EFFICIENT AND ACCURATE VIRTUAL ACCOUSTIC RENDERING
Simplified Explanation: This patent application describes systems and methods for efficiently rendering virtual sound fields by applying principal component analysis techniques to audio signals.
- Systems can generate virtual acoustic renderings from input audio signals with sound source signals.
- Principal component weights are applied to sound source signals to obtain weighted audio streams.
- Principal component filters are applied to the weighted audio streams to obtain filtered audio streams.
- The filtered audio streams are summed into output channels for playback through speakers, creating a virtual acoustic rendering.
Key Features and Innovation:
- Use of principal component analysis to process audio signals for virtual sound field rendering.
- Application of PC weights and filters derived from head-related transfer functions for accurate rendering.
- Summation of filtered audio streams into output channels for realistic playback.
Potential Applications: This technology can be used in virtual reality systems, gaming, audio production, and immersive audio experiences.
Problems Solved: This technology addresses the challenge of accurately rendering virtual sound fields for a realistic audio experience.
Benefits:
- Enhanced virtual sound field rendering.

Original Abstract Submitted
systems and methods are provided for generating processing algorithms, and using such processing algorithms, to efficiently and accurately render virtual sound fields. systems implementing such techniques can generate a virtual acoustic rendering, from an input audio signal comprising at least one sound source signal. such systems apply pc weights to the at least one sound source signal of the input audio signal to obtain at least one weighted audio stream, wherein the pc weights were obtained from a principal components analysis of a set of head-related transfer functions (hrtfs); apply a set of pc filters to the at least one weighted audio stream to obtain filtered audio streams, wherein the pc filters were obtained from a principal components analysis of the hrtfs; sum the filtered audio streams into at least two output channels; and transmit the at least two output channels for playback by the at least two speakers, to generate a virtual acoustic rendering to a listener.
