Harmonic Intensity Regulation for Dynamic Vocal Frequency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music production tools lack flexibility in dynamic equalization and multiband compression, leading to undesirable music quality due to rigid attenuation processes that fail to adjust to variations in vocal characteristics and harmonic frequencies, resulting in compromised sound integrity and loss of richness.
Innovation Solution
The intensity regulation system dynamically adjusts intensity based on harmonic tracking and latching, allowing for real-time changes in frequency bands, enabling precise control over specific harmonic frequencies without affecting nearby frequencies, thus enhancing tone and character of audio signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If rigid attenuation process is used to reduce intensity of frequencies in a preset range, then the attenuation amount is controlled, but the flexibility to adjust to variations in vocal characteristics and harmonic frequencies is lost
Solution Approach 1:
The patent implements dynamic frequency tracking that automatically follows the fundamental frequency and its harmonics throughout the audio signal. Instead of using a fixed preset frequency range, the system continuously adapts the frequency range to match the actual pitch and harmonic structure of the vocal performance, resolving the contradiction between precise attenuation control and adaptability to vocal variations
Solution Approach 2:
The system changes the frequency range parameter dynamically based on the detected fundamental frequency and harmonic content. By adjusting the frequency range to track with pitch changes and register transitions, the system maintains precise control over the intended harmonic while adapting to the varying characteristics of the vocal performance
2Manufacturing precision
If a frequency range is set to control a specific harmonic, then the harmonic intensity is reduced, but nearby desirable frequencies are also affected
Solution Approach 1:
The patent segments the frequency spectrum by identifying and tracking specific harmonics individually. Instead of applying attenuation to a broad fixed frequency range, the system isolates the fundamental frequency and each harmonic, applying attenuation selectively to each segment. This allows precise control over the target harmonic while leaving adjacent desirable frequencies unaffected
Solution Approach 2:
The system applies different attenuation characteristics to different frequency segments. By identifying the specific harmonic that needs control and applying attenuation only to that localized frequency region while tracking it dynamically, the system achieves precise harmonic intensity control without adversely affecting nearby desirable frequencies with different quality requirements
3Ease of operation
If fixed intensity reduction is applied to a harmonic, then the harmonic control is simplified, but the dynamic component and natural variation of the harmonic is lost
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors the intensity of the tracked harmonic and automatically adjusts the attenuation amount in real-time. The system measures the actual intensity of the fundamental frequency and its harmonics, then applies dynamic attenuation based on these measurements, preserving the natural dynamic variations while maintaining control over peak intensities
Solution Approach 2:
The system transitions from static fixed attenuation to dynamic attenuation that responds to the actual performance characteristics. By continuously tracking the harmonic intensity and adjusting the attenuation amount dynamically, the system maintains ease of operation through automated tracking while preserving the natural dynamic component and intensity variations of the harmonic
4Measurement precision
If pitch-tracking equalization is used to follow fundamental frequency changes, then the frequency tracking is improved, but the system still lacks dynamic intensity adjustment capability
Solution Approach 1:
The patent extends pitch-tracking equalization by adding intensity measurement and regulation feedback loops. The system not only tracks the fundamental frequency and harmonic frequencies accurately but also measures their intensities and dynamically adjusts attenuation amounts based on these intensity measurements, thereby adding dynamic intensity regulation capability to the frequency tracking system
