Looping Audio-Visual File Generation via Musical Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio-visual file generation technologies for social media sharing often result in audio content that does not match video content, with audio being truncated, leading to undesirable playback when looped.
Innovation Solution
An AV processor that analyzes audio files based on musical characteristics to identify segment locations, allowing for the synchronization and modification of both audio and video loop portions to create a seamless, loopable audio-visual file, ensuring musically pleasing playback without clipping or losing key video content aspects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If audio content is truncated to match video duration, then video-audio synchronization is improved, but audio musical integrity deteriorates
Solution Approach 1:
The patent segments the audio file into multiple portions based on musical characteristics (beats, measures, phrases) and selectively combines these segments to create a loopable audio composition that maintains musical integrity while matching the video duration. This segmentation allows precise control over which audio portions are included, resolving the contradiction between synchronization and musical integrity.
Solution Approach 2:
The patent performs preliminary analysis of the audio file to identify segment locations based on musical characteristics before finalizing the loopable composition. This preliminary action allows the system to pre-determine optimal cut points that preserve musical structure, avoiding arbitrary truncation that would compromise audio quality.
2Duration of action of stationary object
If arbitrary audio truncation is applied, then file loopability is improved, but audio quality deteriorates
Solution Approach 1:
The patent divides the audio file into musically coherent segments based on beats, measures, and phrases, then reassembles these segments to create a loopable composition. This ensures that loop points occur at musically appropriate locations rather than arbitrary positions, maintaining audio quality while achieving loopability.
Solution Approach 2:
The patent changes the temporal parameters of audio segments by selectively including or excluding portions based on musical characteristics. This allows the system to adjust the effective duration and structure of the audio to match video requirements while preserving musical integrity through intelligent parameter modification.
3Manufacturing precision
If manual audio editing is performed to maintain musical integrity, then audio quality is improved, but processing time increases
Solution Approach 1:
The patent implements automatic analysis of audio files to identify segment locations based on musical characteristics such as beats, measures, and phrases. This self-service approach eliminates the need for manual editing while maintaining high audio quality, as the system autonomously determines optimal segment boundaries that preserve musical integrity.
Solution Approach 2:
The patent replaces manual mechanical editing processes with automated digital signal processing and musical analysis algorithms. This substitution maintains audio quality through precise automated segmentation while dramatically reducing processing time compared to manual editing methods.

AI summary
In one general aspect, a method can include receiving a video loop portion included in a video file and receiving an audio loop portion included in an audio file. The method can include analyzing at least a portion of the audio file based on a musical characteristic and identifying a plurality of segment locations within the audio file based on the analyzing where the plurality of segment locations define a plurality of audio segments of the audio file. The method can also include modifying the video loop portion based on one of the plurality of segment locations in the audio file.
