Audiovisual Playback Synchronization With Variable Tempo Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to effectively isolate individual musical instrument tracks from a preselected piece of music, making it difficult for musicians to learn and emulate the music accurately, especially for those who cannot read music, and lack the ability to record and mix their performance with pre-recorded portions for self-critique.
Innovation Solution
A system comprising a processor, input device, database, transformation module, emulation recording module, integration engine, and output device that allows users to obtain a custom digital audio file, isolate and emulate a musical instrument track, record and combine it with an emulation track, and listen to the educational track to identify and correct deficiencies in their performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-track recording technology is used to compile music with reduced number of tracks, then distribution efficiency is improved, but the ability to access individual instrument contributions deteriorates
Solution Approach 1:
The patent segments the compiled music into separate isolated instrument audio tracks, allowing each instrument to be individually accessed and studied while maintaining the overall compiled music structure for distribution
2Difficulty of detecting and measuring
If equalization or algorithms are used to mask other sounds or pull out particular frequencies, then sound separation is attempted, but the isolation quality is insufficient
Solution Approach 1:
The patent creates accurate copies of isolated instrument tracks from the original multi-track recording, preserving the complete audio quality and all articulations without the degradation caused by equalization or masking algorithms
3Ease of operation
If musicians play along with embedded mix recording, then learning process is attempted, but the ability to clearly identify all aspects of the music deteriorates
Solution Approach 1:
The patent introduces isolated instrument audio tracks as an intermediary between the compiled music and the learner, providing a clear reference for emulation while maintaining the ability to compare with the original embedded mix
4Adaptability or versatility
If modified musical compilation with removed instrument is used, then practice opportunity is provided, but the ability to listen to the instrument alone with details deteriorates
Solution Approach 1:
The patent extracts the specific instrument track from the compiled music, allowing learners to study the isolated instrument with all its details and articulations, while also providing the option to recombine it with other tracks for complete piece practice

AI summary
A playback system is provided for altering the frame rate of streaming digital movie data for synchronizing with audio data recording to create a synchronized audiovisual work. The system can have a video that is synchronized with the variations in the tempo of the audio data through a variable timing reference track designed and provided for a user, wherein the designing of the variable timing reference track includes creating a tempo map having variable tempos, rhythms, and beats using notes from the audio data.
