Dynamic Music Version Switching for Video Voice Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When creating video edits, the interference between singing voices in the music and voices in the video can degrade the quality, making it difficult to understand either voice, especially when they overlap, and existing solutions like volume reduction can disrupt the viewer's experience.
Innovation Solution
A system that utilizes multiple versions of music for video playback by identifying parts where the audio content includes voice and replacing corresponding parts of the singing music with instrumental music, ensuring the instrumental version is used as accompaniment during voice overlaps, thereby maintaining audio clarity without disrupting the viewer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the singing version of music is used as accompaniment for the entire video, then the musical experience is enhanced, but the audio clarity deteriorates when voices overlap
Solution Approach 1:
The system dynamically switches between the singing version and instrumental version of music based on real-time voice detection in the video. When voices are detected, the system transitions to the instrumental version to avoid interference, and switches back to the singing version when voices are absent, thus adapting the music accompaniment to the current audio conditions
Solution Approach 2:
The music accompaniment is segmented into two distinct versions: a singing version for segments where no voice overlap occurs, and an instrumental version for segments where voice overlap is detected. This segmentation allows each version to be optimized for its specific functional context, with the singing version providing full musical experience and the instrumental version ensuring audio clarity
2Object-affected harmful factors
If the volume of singing music is reduced to avoid voice interference, then the audio clarity improves, but the musical experience deteriorates
Solution Approach 1:
The system extracts the singing voice component from the music track and separates it from the instrumental accompaniment. By removing the singing voice element during segments where video voices are present, the system eliminates the source of interference without requiring volume reduction, thus preserving full musical experience during non-overlapping segments
3Object-affected harmful factors
If the instrumental version of music is used throughout the video, then the audio clarity is maintained, but the musical experience is reduced
Solution Approach 1:
The system applies different music versions to different temporal segments of the video based on local voice presence conditions. The singing version is applied locally to segments without voice overlap, while the instrumental version is applied locally to segments with voice overlap, ensuring optimal audio quality in each specific context rather than applying a uniform version throughout

AI summary
A playback of a video may be generated to include accompaniment of music. For parts of the video that includes voice, an instrumental version of the music may be used. For parts of the video that does not include voice, a singing version of the music may be used.
