Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual addition of sound effects is used, then video special effects can have sound effects, but the process is time-consuming and laborious
Solution Approach 1:
The system pre-prepares multiple sound effect libraries categorized by different virtual object types (fire, water, wind, etc.) and states (generation, burning, extinguishing). These sound effects are prepared in advance and mapped to corresponding virtual object attributes, so when a virtual object is generated in the video, the appropriate sound effect is automatically selected and applied without manual intervention or time-consuming dubbing processes.
2Adaptability or versatility
If fixed sound effects are used, then video special effects have sound effects, but the sound effects are inflexible and cannot handle real-time changes
Solution Approach 1:
The system dynamically adjusts sound effects based on real-time virtual object attributes. When virtual objects change states (e.g., flame size, water flow rate, wind intensity), the system automatically modifies the corresponding sound effects to match the new state. This dynamic adaptation allows sound effects to flexibly respond to real-time changes in video special effects without requiring manual reconfiguration or fixed pre-dubbed tracks.
Solution Approach 2:
The system changes sound effect parameters (volume, pitch, duration, intensity) based on virtual object attribute parameters. For example, when the size or intensity of a virtual fire object changes, the corresponding fire sound effect's volume and intensity parameters are automatically adjusted to match. This parameter-based control enables flexible real-time sound effect adaptation to varying video special effect conditions.
3Ease of manufacture
If pre-dubbed sound tracks are used, then video production is simpler, but the sound effects cannot change in real time
Solution Approach 1:
The system implements self-service automatic sound effect matching and application. When virtual objects are generated or modified in the video, the system automatically detects the object type and state, selects the appropriate sound effect from pre-prepared libraries, and applies it without requiring manual dubbing or post-processing. This self-service mechanism maintains video production simplicity while enabling real-time sound adaptation to changing virtual objects.

AI summary
A sound processing method, a sound processing apparatus, an electronic device and a computer-readable storage medium are provided in the present disclosure. The sound processing method includes: acquiring a video image from a video source in response to receiving a first trigger signal; superimposing a first virtual object in the video image in response to receiving a second trigger signal; acquiring attribute information of the first virtual object; acquiring a sound and a sound parameter corresponding to the first virtual object according to the attribute information; and adjusting the sound according to the sound parameter to obtain a sound corresponding to a state of the first virtual object.
