Game Audio Volume Adjustment by Sound Category Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for video games struggle to automatically adjust sound volumes effectively, particularly for specific sound categories like gunfire or explosions, which can impact player experience and reaction time.
Innovation Solution
An electronic device equipped with an audio recognition module and an audio adjustment module that recognizes predetermined sound categories in audio data and adjusts the volume accordingly, using a volume gain determined by the identified sound category.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual volume adjustment is used for different sound categories, then players can control specific sound volumes, but the operation complexity increases and automatic adaptation is lost
Solution Approach 1:
The audio processing system automatically identifies sound categories and adjusts their volumes without requiring manual player intervention. The system serves itself by autonomously analyzing audio data, categorizing sounds, and applying volume adjustments based on game context and player position, eliminating the need for complex manual controls while maintaining adaptability
Solution Approach 2:
The system dynamically changes audio parameters (volume gains) based on detected sound categories and game context. By automatically modifying volume parameters for different sound types such as gunfire, explosions, and footsteps, the system achieves adaptive audio adjustment without increasing operational complexity for the player
2Reliability
If all sounds are played at equal volume, then the audio system is simple, but important game sounds may be overwhelmed and player reaction time increases
Solution Approach 1:
The system applies different volume adjustments to different sound categories based on their importance and player position. Critical sounds like gunfire and explosions near the player are amplified with higher volume gains, while less important sounds maintain lower volumes, ensuring reliable detection of important game events without uniformly increasing all sound volumes
Solution Approach 2:
The system continuously monitors audio data and game context to dynamically adjust sound volumes. By providing real-time feedback about player position, sound category, and game state, the system optimizes volume levels to ensure important sounds are always detectable, improving both reliability and response efficiency
3Manufacturing precision
If volume adjustment processing is applied to all audio data, then all sounds are optimized, but the processing time and computational resources increase
Solution Approach 1:
The audio processing system divides audio data into distinct categories (gunfire, explosions, footsteps, etc.) and applies volume adjustment processing selectively to each category. By segmenting the audio stream and processing only relevant sound categories with appropriate volume gains, the system maintains high processing precision while reducing overall computational time and resources required

AI summary
An automatic adjustment method includes: recognizing whether one of a plurality of predetermined sound categories is included in audio data of current game; when one of the predetermined sound categories is included in the audio data, determining volume gain based on the predetermined sound category included in the audio data; and adjusting the volume of the audio data according to the volume gain.
