Solution Overview

Problem

Conventional methods for adjusting chat audio volume in gaming environments require manual user intervention, which disrupts gameplay, and fail to maintain chat audio intelligibility during dynamic changes in game audio volume.

Innovation Solution

An automatic volume control system that dynamically adjusts chat and game audio levels based on signal strength analysis, using envelope detection and gain control to ensure clear chat audio despite varying game audio dynamics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual user intervention is used to adjust chat audio volume, then chat audio volume can be controlled, but gameplay is disrupted and user experience deteriorates

Engineering Contradiction:
Improvechat audio volume controlVSAvoidgameplay interruption
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system automatically detects game audio levels and adjusts chat audio volume without user intervention. The envelope detector continuously monitors game audio signals and the controller automatically modifies chat audio gain based on detected audio dynamics, enabling the system to serve itself rather than requiring manual user control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements a feedback loop where the envelope detector continuously monitors game audio levels and feeds this information back to the controller, which then adjusts chat audio volume accordingly. This closed-loop control ensures chat audio automatically adapts to changing game audio conditions without user intervention.

Inventive Principle:
Principle #23Feedback

2Device complexity

If fixed chat audio volume is used, then system simplicity is maintained, but chat audio intelligibility deteriorates during dynamic game audio changes

Engineering Contradiction:
Improvevolume control systemVSAvoidchat audio intelligibility
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system transitions from fixed volume control to dynamic adjustment by incorporating an envelope detector that continuously tracks game audio level changes. The controller dynamically modifies chat audio gain in real-time based on detected audio envelope characteristics, ensuring chat intelligibility adapts to varying game audio conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the volume parameter of chat audio dynamically based on game audio conditions. The envelope detector identifies audio level parameters and the controller adjusts chat audio gain accordingly, transforming the static volume parameter into a dynamic one that responds to game audio variations.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If envelope detection and gain control are implemented, then chat audio intelligibility is maintained, but device complexity increases

Engineering Contradiction:
Improvechat audio intelligibilityVSAvoidaudio processing system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The audio processing system is segmented into distinct functional modules: an envelope detector that separates game audio analysis from chat audio processing, and a controller that independently manages gain adjustment. This segmentation allows each module to perform its specific function efficiently without requiring complete system redesign.

Inventive Principle:
Principle #1Segmentation

AI summary

A system may comprise an input circuit, one or more filter circuits, one or more common signal detection circuits, and a controller. The input circuit may receive combined-game-and-chat audio signals generated from a mixing together of a chat audio signal and game audio signals. The filter circuit(s) may filter a first of the combined-game-and-chat audio signals to generate a first vocal-band signal and a first non-vocal-band signal, and filter a second of the combined-game-and-chat audio signals resulting in a second vocal-band signal and a second-non-vocal band signal. The common signal detection circuit(s) may detect strength of a signal component that is common to the first vocal-band signal and the second vocal-band signal, and strength of a signal component that is common to the first non-vocal-band signal and the second non-vocal-band signal. The controller may automatically control a volume setting based on one or both of the detected strengths.
