Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio technologies primarily utilize stereo sound, which limits the ability to create immersive three-dimensional audio experiences, as most media creators lack the tools and knowledge to design and implement 3D audio environments.
Innovation Solution
The use of multimodal machine learning methods and neural networks to automatically generate three-dimensional audio by segmenting and associating image and audio elements from multimedia content, such as videos and games, to create spatially accurate soundtracks that mimic real-world environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional stereo sound is used, then device complexity is reduced and ease of operation is improved, but audio immersion and spatial accuracy are limited
Solution Approach 1:
The system automatically generates 3D audio from existing stereo media without requiring manual intervention or specialized knowledge from content creators. The machine learning model processes input audio and images to autonomously produce spatially accurate soundtracks, making 3D audio implementation self-service rather than requiring expert expertise
Solution Approach 2:
The patent transforms audio from two-dimensional stereo channels to three-dimensional spatial distribution by changing the parameter representation. The machine learning model maps audio parameters to spatial coordinates, converting traditional stereo audio into immersive 3D audio experiences while maintaining compatibility with existing media
2Adaptability or versatility
If manual 3D audio design is performed, then audio quality and immersion are improved, but device complexity and time consumption increase
Solution Approach 1:
The machine learning model is pre-trained on extensive datasets of audio-visual pairs, performing the complex analysis and generation work in advance. During actual use, the model quickly processes new input media by applying learned patterns, eliminating the need for time-consuming manual 3D audio design while maintaining high quality
Solution Approach 2:
The patent replaces manual audio engineering processes with an automated machine learning system. Instead of requiring audio professionals to manually create 3D audio experiences, the system uses neural networks to automatically process media and generate immersive soundtracks, substituting mechanical manual work with intelligent automation
3Adaptability or versatility
If machine learning-based 3D audio generation is implemented, then audio immersion and spatial accuracy are improved, but computational resources and processing time increase
Solution Approach 1:
The system segments the audio processing task into distinct stages: input media analysis, spatial mapping, and audio generation. The machine learning model processes audio and visual inputs separately before integrating them to produce final 3D audio, reducing computational load compared to processing everything simultaneously while maintaining immersion quality
