Solution Overview

Problem

The music industry faces challenges in re-purposing well-known songs due to the time and expense involved in re-recording new versions, and many unused audio and MIDI files from back catalogs are difficult to reuse effectively.

Innovation Solution

A method and system that generates audio or MIDI output files by using harmonic chord maps to select and combine pre-recorded content blocks with input files, adapting musical performances to various harmonic keys and tempos, and allowing for editing and mixing to create unique accompaniments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If re-recording new versions of old songs is performed to re-purpose well-known songs, then new musical content can be created for production industries, but significant time and expense are required

Engineering Contradiction:

Improvere-purposing capabilityVSAvoidre-recording time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system pre-processes original recordings by extracting instrumental tracks, separating stems, and creating reusable content blocks before they are needed. This preliminary preparation allows rapid assembly of new versions without time-consuming re-recording sessions

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent divides original song recordings into separate content blocks (vocal tracks, instrumental tracks, stems) that can be independently selected and recombined. This segmentation enables efficient creation of new versions by mixing and matching pre-separated elements

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If re-recording new versions of old songs is performed to re-purpose well-known songs, then new musical content can be created for production industries, but significant expense is required

Engineering Contradiction:

Improvere-purposing capabilityVSAvoidre-recording cost

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The system creates digital copies and derivatives of original recordings by extracting and recombining audio stems. Instead of expensive re-recording sessions, the system generates new versions through digital manipulation and assembly of existing recorded elements

Inventive Principle:

Principle #26Copying

Solution Approach 2:

Inventive Principle:

Principle #10Preliminary action

3Quantity of substance

If unused out-takes from back catalogs are reused, then hidden gems can be discovered and repurposed, but these files are difficult to find and use effectively

Engineering Contradiction:

Improveunused content availableVSAvoidreuse difficulty

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The system automatically analyzes, tags, and organizes out-take files by detecting tempo, key, and structural characteristics. This self-organizing capability makes unused content easily searchable and reusable without manual cataloging effort

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces a content management system that acts as an intermediary between stored out-take files and users. This intermediary automatically processes, tags, and presents relevant content blocks, bridging the gap between hidden gems and effective reuse

Inventive Principle:

Principle #24Intermediary (Mediator)

4Productivity

If content blocks are automatically selected using harmonic chord maps, then new versions can be generated efficiently, but ensuring harmonic integrity and uniqueness becomes complex

Engineering Contradiction:

Improvegeneration speedVSAvoidselection system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system uses harmonic chord maps to analyze and match musical parameters (tempo, key, chord progression) between content blocks and target songs. By automatically adjusting and matching these parameters, the system ensures harmonic integrity while maintaining efficient automated selection

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent implements feedback mechanisms where the system evaluates selected content blocks against harmonic requirements and refines selections accordingly. This feedback loop ensures uniqueness and quality while automating the complex selection process

Inventive Principle:

Principle #23Feedback

AI summary

Techniques are provided for generating an output file. One technique involves the steps of generating audio or MIDI content blocks from one or more musical performances; receiving an input file having audio or MIDI music content; generating a harmonic chord map for the input file; using the harmonic chord map to automatically select a subset of the audio or MIDI content blocks, and generating the output file by combining the selected subset of content blocks and the input file. This technique may enable the creation of unique and new musical accompaniments by re-purposing audio or MIDI content from back catalogs and/or out-takes of musical works. The new arrangement may be provided in multiple music styles, genres, or moods and may contain performances from multiple musical instruments, which may be pre-recorded from live instrument performances and/or of MIDI generated musical content.
