Object-Based Audio Rendering with Speaker-Position Gain Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio rendering technologies in object-based formats often produce undesired results when there are insufficient speakers in certain areas, leading to impaired audibility of audio components and mismatched audio effects.
Innovation Solution
Adjusting the gain value of audio content based on the positions of speakers at the media consumption site using object-based metadata, categorizing speakers into position categories, and determining maximum adjustment values to ensure optimal audio playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If audio content is played through speakers not positioned at the intended location, then the audio can be played at all, but the audio effect becomes mismatched and position accuracy deteriorates
Solution Approach 1:
The patent changes the gain parameter of audio content based on the position mismatch between intended speaker location and actual speaker location. By adjusting the gain value, the system compensates for the positional discrepancy and maintains accurate sound positioning even when speakers are not located at the intended positions.
2Productivity
If audio content is played through available speakers without augmentation, then playback is possible, but the audibility of other audio components is impaired
Solution Approach 1:
The patent adjusts the gain parameter of audio content based on speaker position categories and configuration. By dynamically changing the gain value, the system ensures that audio components remain audible and distinguishable even when played through speakers not positioned at their intended locations, thus maintaining the reliability of audio component perception.

AI summary
The positions of a plurality of speakers at a media consumption site are determined. Audio information in an object-based format is received. Gain adjustment value for a sound content portion in the object-based format may be determined based on the position of the sound content portion and the positions of the plurality of speakers. Audio information in a ring-based channel format is received. Gain adjustment value for each ring-based channel in a set of ring-based channels may be determined based on the ring to which the ring-based channel belongs and the positions of the speakers at a media consumption site.
