Music Metadata Delivery for Stem-Based Audio Post-Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music distribution systems fail to distribute stem-based content ubiquitously due to the requirement of pre-mixed stereo formats, limiting applications like karaoke and music track remixing that necessitate multiple tracks.
Innovation Solution
The system extracts application-specific stems from standard pre-mixed content, generates metadata, and distributes it with the original content to enable post-processing, ensuring compatibility and enhancing user experiences through real-time audio processing effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If music content is distributed in pre-mixed stereo format, then compatibility with existing playback systems is maintained, but stem-based content cannot be distributed ubiquitously
Solution Approach 1:
The system performs preliminary extraction of stems and generation of metadata during the music content delivery phase, before the actual application use. This allows receiving systems to have stem-based content readily available without needing complex real-time separation capabilities, resolving the contradiction between adaptability and device complexity
Solution Approach 2:
The patent introduces metadata as an intermediary element that carries information about extracted stems and applied effects. This metadata acts as a bridge between the pre-processed stem-based content and various applications, enabling versatile use without requiring complex processing at the receiving end
2Adaptability or versatility
If stem-based content is distributed as multiple supplemental tracks, then applications like karaoke and remixing can utilize subsets of stems, but music distribution becomes limited to pre-mixed stereo format
Solution Approach 1:
The system creates a universal stem-based content format that can serve multiple applications (karaoke, remixing, analysis, etc.) through a single distribution mechanism. The extracted stems and metadata work together to enable various applications without requiring separate distribution systems for each use case
Solution Approach 2:
The patent creates copies of the music content in stem-separated form with associated metadata, allowing multiple applications to access and process the same source material in different ways. This copying approach enables versatile application support while maintaining simple distribution through standardized formats
3Reliability
If audio processing effects are applied to match original music content sound quality, then user audio input integrates seamlessly, but processing time and computational resources increase
Solution Approach 1:
The system pre-analyzes the original music content to identify and characterize applied effects during the metadata generation phase. This preliminary analysis stores effect parameters and characteristics that can be quickly applied to user audio input during real-time processing, maintaining sound quality consistency without excessive processing time
Solution Approach 2:
The system uses the metadata about original effects as feedback to guide the processing of user audio input. By referencing the pre-analyzed effect parameters stored in metadata, the system can automatically apply appropriate processing to match the original sound quality without requiring complex real-time analysis
