Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In audio signal processing for special effects and games, variations in sound volume due to distance and microphone settings lead to inaccurate audio collection, affecting the control of display effects in virtual scenes.
Innovation Solution
An audio signal processing method that determines a reference sound volume based on collected audio signals, followed by audio signal sampling to establish a basis sound volume, which is used to control display effects in virtual scenes, independent of distance and microphone settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If audio signal is collected directly from microphone, then audio collection is simple, but sound volume varies due to distance and microphone settings leading to inaccurate control
Solution Approach 1:
The patent applies preliminary action by collecting audio signals in a first time period to determine a reference sound volume before performing sampling in a second time period. This preliminary reference measurement enables subsequent sampling to be compared against a established baseline, improving measurement accuracy while maintaining manageable processing complexity through structured temporal separation of reference and measurement phases.
Solution Approach 2:
The patent segments the audio signal processing into distinct time periods: a first time period for collecting reference audio signals to establish reference sound volume, and a second time period for sampling audio signals at multiple points to determine basis sound volume. This temporal segmentation allows the system to separate reference establishment from measurement, improving accuracy while keeping each phase's processing complexity manageable.
2Reliability
If multiple audio sampling points are used to determine basis sound volume, then accuracy of control is improved, but processing time and complexity increase
Solution Approach 1:
The patent uses preliminary action by establishing a reference sound volume from audio signals collected in a first time period before performing multiple sampling operations in a second time period. This preliminary reference enables faster comparison and evaluation during the sampling phase, improving control reliability while reducing the computational burden and time required for each individual sampling measurement.
Solution Approach 2:
The patent implements periodic action by structuring audio signal collection and sampling into distinct time periods with specific purposes. The first time period is dedicated to reference collection, while the second time period performs periodic sampling at multiple points. This periodic structure allows the system to balance comprehensive measurement (multiple sampling points) with efficient processing by confining intensive operations to designated time windows.

AI summary
An audio signal processing method, an audio signal processing apparatus, a terminal, and a storage medium are provided. In the method, audio signal in a first period of time is collected. A reference sound volume is determined based on the collected audio signal. Audio signal sampling is performed on the audio signal at multiple audio sampling points in a second period of time to obtain multiple audio sampling signals. In a case of determining that the multiple audio sampling signals meet a predetermined condition based on the reference sound volume, a basis sound volume is determined based on the multiple audio sampling signals. The basis sound volume is used for controlling a display effect of a target object in a virtual scene, and different basis sound volumes correspond to different display effects of the target object.
