Personalized EQ Blending for Consistent Audio Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio playback systems require frequent manual adjustments of equalization settings due to varying audio characteristics across different media sources and genres, leading to an inconsistent listening experience.
Innovation Solution
A system that dynamically adjusts audio playback settings, such as equalization, based on real-time analysis of audio signals using a neural network trained on reference media, incorporating smoothing filters to avoid perceptible changes and thresholding techniques to smooth out equalization curves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustments of equalization settings are used for different media sources, then audio playback can be customized for specific sources, but user convenience deteriorates due to frequent manual intervention required
Solution Approach 1:
The system automatically analyzes audio signal characteristics and adjusts equalization settings without requiring user intervention. The processor continuously monitors incoming audio signals, identifies source characteristics, and dynamically modifies playback parameters, enabling the system to serve itself rather than requiring manual user configuration for each media source
Solution Approach 2:
The equalization settings are made dynamic rather than static, allowing the system to continuously adapt playback parameters based on real-time analysis of audio signal characteristics. The processor adjusts frequency responses, volume levels, and other audio parameters dynamically as different media sources are detected, providing adaptability without manual intervention
2Stability of the object's composition
If equalization settings are adjusted for each media source, then audio consistency improves, but system complexity increases due to multiple configuration requirements
Solution Approach 1:
The system performs preliminary analysis of audio signal characteristics as audio begins to play, automatically establishing appropriate equalization settings based on detected source properties. This preliminary characterization enables consistent audio output across different sources without requiring pre-configuration or complex manual setup procedures
Solution Approach 2:
A single automated processing system handles multiple media sources and adjusts various audio parameters (equalization, volume, frequency response) through one unified mechanism. The processor universally analyzes different audio sources and applies appropriate settings, eliminating the need for separate configuration systems for each media type
3Speed
If rapid changes in equalization settings are applied, then responsiveness to different media sources improves, but perceptible audio disruptions occur
Solution Approach 1:
The system applies equalization changes in periodic or staged increments rather than all at once. When adjusting settings in response to detected media characteristics, the processor implements changes over multiple time intervals, allowing the audio system to adapt gradually and maintain smooth transitions that are imperceptible to listeners while still responding quickly to source changes

AI summary
Methods, apparatus, systems and articles of manufacture are disclosed for playback using pre-processed profile information and personalization. Example apparatus disclosed herein include a synchronizer to, in response to receiving a media signal to be played on a playback device, access an equalization (EQ) profile corresponding to the media signal; an EQ personalization manager to generate a personalized EQ setting; and an EQ adjustment implementor to modify playback of the media signal on the playback device based on a blended equalization generated based on the EQ profile and the personalized EQ setting.
