Audio Volume Processing Method for Smooth Sound Effect Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User terminals often experience sudden volume changes when adding sound effects to audio/video files, leading to auditory discomfort and reduced user experience due to excessive noise.
Innovation Solution
A volume processing method that records the initial volume output value of an audio file, decreases it to a second output value before configuring sound effects, and gradually increases it back to the initial value using a volume increasing model, ensuring a smooth transition and maintaining auditory comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sound effect parameters are configured directly to the audio file without volume adjustment, then the sound effect can be added efficiently, but sudden volume changes occur causing auditory discomfort and noise
Solution Approach 1:
The patent applies preliminary action by adjusting the volume of the original audio file before adding sound effects. Specifically, the system decreases the volume of the original audio to a lower level before the sound effect is configured, preventing sudden volume changes and auditory discomfort. This preparatory volume adjustment ensures that when the sound effect is added, the overall audio output remains comfortable and avoids noise.
2Object-affected harmful factors
If the volume of the audio file is decreased before adding sound effects, then auditory comfort is maintained, but the original audio volume is reduced
Solution Approach 1:
The patent applies periodic action by implementing a two-stage volume adjustment process. First, the volume of the original audio is decreased to a lower level before adding sound effects. Second, after the sound effect is configured, the volume of the original audio is increased back to its initial level. This periodic volume adjustment ensures that during the sound effect configuration period, the volume is low to maintain comfort, but after configuration, the original audio volume is restored to maintain quality.
3Object-affected harmful factors
If volume adjustment is implemented smoothly with a volume increasing model, then auditory comfort is improved, but the processing time and complexity increase
Solution Approach 1:
The patent applies parameter changes by implementing a volume increasing model that gradually adjusts the volume parameter from a lower level back to the initial level after sound effect configuration. This model controls the rate and pattern of volume increase to ensure smooth transitions that maintain auditory comfort. The parameter change approach provides a systematic way to manage volume transitions without requiring complex hardware modifications.

AI summary
Disclosed are a volume processing method and a user terminal. In the method, an initial volume output value of an audio file is recorded as a first output value, the volume output value of the audio file is decreased to a second output value in advance before a parameter of sound effect is configured to the audio file, and the volume output value is adjusted from the second output value to the first output value step by step according to a volume increasing model after the parameter of sound effect is configured.
