Automatic Chat Audio Volume Control in Mixed Game Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multiplayer gaming, the wide dynamic range of game audio often overwhelms chat audio, making it difficult for users to hear voice communications, especially during intense game moments, as conventional solutions require manual volume adjustments that disrupt gameplay.
Innovation Solution
The implementation of automatic volume control systems in gaming consoles and headsets that detect the strength of chat and game audio components and adjust volume settings dynamically to maintain audible chat audio, using audio processing units and enhancement circuitry to mix and process combined-game-and-chat audio signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual volume adjustment is used to ensure chat audio is audible, then chat audio intelligibility is improved, but gameplay continuity deteriorates due to user distraction
Solution Approach 1:
The system automatically monitors and adjusts the relative volumes of game audio and chat audio without user intervention. The audio processing unit detects when chat audio becomes inaudible against game audio background and autonomously adjusts volume levels, allowing the system to serve itself rather than requiring manual user control.
Solution Approach 2:
The system implements a feedback mechanism where the audio processing unit continuously monitors the混合 audio signal, detects when chat audio intelligibility deteriorates due to loud game audio, and automatically adjusts volume levels in response. This closed-loop control ensures chat audio remains audible without user intervention.
2Use of energy by moving object
If game audio volume is increased for immersive experience, then gaming enjoyment is improved, but chat audio detectability deteriorates
Solution Approach 1:
The system dynamically adjusts volume levels based on real-time audio conditions rather than using fixed settings. The audio processing unit continuously adapts the relative volumes of game audio and chat audio, allowing game audio to be high for immersion while automatically boosting chat audio when needed to maintain detectability.
Solution Approach 2:
The system changes audio parameters (volume levels) automatically based on detected audio conditions. When game audio intensity exceeds a threshold that compromises chat audio detectability, the system adjusts the volume parameters of both game audio and chat audio to maintain optimal intelligibility while preserving gaming enjoyment.
3Measurement precision
If automatic volume control is implemented, then chat audio intelligibility is maintained, but device complexity increases
Solution Approach 1:
The audio processing unit acts as an intermediary between the game audio source and the user's ears. It monitors the mixed audio signal and automatically adjusts volume levels, serving as a mediator that resolves the conflict between game audio intensity and chat audio intelligibility without requiring complex user-side adjustments.
4Adaptability or versatility
If separate game and chat audio channels are provided, then volume adjustment flexibility is improved, but system compatibility deteriorates when premixed audio is used
Solution Approach 1:
The system segments the audio processing function into distinct components: it separates chat audio detection from game audio processing, and implements independent volume control for each channel. This segmentation allows the system to handle both separate and premixed audio configurations reliably, as each audio component can be processed independently regardless of how they were originally combined.
Data Source
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.
