Solution Overview

Problem

Conventional audio systems fail to adapt spatialization based on content type, leading to a limited user experience.

Innovation Solution

An audio system that uses a content classifier to determine the type of audio content and automatically selects a spatialization mode from a plurality of modes based on the content type, applying it to the audio output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional audio systems apply spatialization to all audio content, then the user experience is enhanced for immersive content, but the system complexity increases and user experience deteriorates for content types that do not benefit from spatialization

Engineering Contradiction:

Improveadaptability to different content typesVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system changes the spatialization parameter dynamically based on content type. A content classifier analyzes audio characteristics and switches between spatialization modes (e.g., immersive spatialization, conventional stereo, or no spatialization) depending on the detected content type, thereby adapting the system behavior to match content requirements without permanently increasing complexity

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The spatialization system transitions from a static fixed configuration to a dynamic adaptive configuration. The controller continuously monitors content characteristics and adjusts spatialization parameters in real-time, allowing the system to optimize performance for each content type while maintaining manageable complexity through automated decision-making

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the system automatically selects spatialization modes without user input, then the ease of operation improves, but the reliability may worsen due to potential misclassification of content types

Engineering Contradiction:

Improveease of operationVSAvoidreliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system incorporates feedback mechanisms where the content classifier continuously monitors audio characteristics and adjusts spatialization selections based on detected patterns. User feedback can also be incorporated to refine the classifier over time, improving reliability while maintaining automatic operation. The system learns from usage patterns and content characteristics to make more accurate automatic decisions

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs self-service by automatically analyzing content characteristics and selecting appropriate spatialization modes without requiring user intervention. The content classifier operates autonomously to determine the best spatialization configuration based on the audio content itself, eliminating the need for manual user input while maintaining high reliability through intelligent automation

Inventive Principle:

Principle #25Self-service

AI summary

Various implementations include audio devices and methods for spatializing audio output based on content. Certain implementations include at least one audio output device for providing an audio output based on data, and at least one controller coupled with the at least one audio output device, the controller configured to, use the data to determine a content type for the audio output from a group of content types, using a trained content classifier, and take an action based on the determined content type.
