AI Technical Summary

Technical Problem

Rendering high-quality immersive audio on power-limited devices is computationally expensive, leading to degraded audio quality and a poor listener experience due to complexity constraints.

Method used

A method and apparatus that determine a rendering control value for each audio source based on perceptual relevance parameters, comparing it to a threshold to cull, cluster, or typecast audio sources, reducing the number of sources rendered without degrading audio quality, using parameters like loudness, positional proximity, and occlusion.

Benefits of technology

This approach decreases computational workload while maintaining audio quality by selectively modifying or deactivating audio sources, resulting in a reduced number of rendered sources without perceptual quality degradation, thus enhancing the listener experience.

Abstract

Described herein is a method of rendering audio sources, the method comprising: determining, for each of a plurality of audio sources, a rendering control value based on one or more parameters indicative of a perceptual relevance of the respective audio source; comparing, for each of the plurality of audio sources, the rendering control value to a perceptibility threshold to determine whether a respective audio source fulfills a perceptual irrelevance criterion; modifying audio sources, out of the plurality of audio sources, for which the rendering control value satisfies the threshold to obtain modified audio sources; and rendering unmodified audio sources, out of the plurality of audio sources, relative to the modified audio sources. Described are further methods for processing audio, respective apparatus and computer program products.
