Dynamic Sound Effect Selection for Video Music Apps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices struggle to play appropriate sounds for integrated applications that handle both video and music, as they cannot accurately determine the corresponding sound effect based on the application name.
Innovation Solution
The proposed method involves determining the sound effect for an application by checking its category and preset conditions, or by analyzing the frame rate and area proportion of the displayed picture to select an appropriate sound effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the mobile phone queries sound effect based on application name, then the sound effect matches the application type, but integrated applications that play both video and music cannot get the appropriate sound effect
Solution Approach 1:
The patent makes the sound effect selection dynamic by switching from a static application-name-based query to a dynamic scenario-based selection. The system dynamically determines whether the application is playing video or music by detecting frame rate changes, and accordingly selects different sound effects (video sound effect or music sound effect) to match the current playing scenario.
Solution Approach 2:
The patent changes the selection parameter from application name to playing scenario characteristics (frame rate). By monitoring the frame rate parameter of the application, the system can distinguish between video playing (higher frame rate) and music playing (lower or zero frame rate), and select the appropriate sound effect based on this parameter change.
2Ease of operation
If the mobile phone uses a default sound effect for integrated applications, then the system is simple to operate, but the sound effect does not match the current sound playing scenario
Solution Approach 1:
The system automatically determines the current playing scenario by monitoring frame rate changes and self-selects the appropriate sound effect without requiring user intervention. The electronic device itself performs the scenario recognition and sound effect selection, making the system both simple to operate and reliable in matching sound effects to scenarios.
Solution Approach 2:
The system continuously monitors the frame rate parameter as feedback to determine the current playing scenario. Based on this feedback, the system automatically adjusts the sound effect selection to match the current scenario, ensuring both ease of operation and reliability.

AI summary
A sound playing method and device, relate to the field of artificial intelligence, so as to resolve a problem that a corresponding sound cannot be played on an application that can play both a video and music by using a corresponding sound effect. A specific solution is as follows: when a category of the first application meets a preset condition, playing a sound of the current first application based on a sound effect parameter of a first sound effect corresponding to the category of the first application; or when the category of the first application does not meet the preset condition, playing the sound of the current first application based on a sound effect parameter of a second sound effect corresponding to a frame rate of a currently displayed picture.
