Playback Volume Pre-Adjustment for Balanced Media Loudness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media playback systems require manual volume adjustments post-equalization, affecting user experience.
Innovation Solution
A method to dynamically adjust the initial volume of media data based on volume adjustment types and current playback attributes, using classification models and regression processing to determine optimal volume adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual volume adjustment is required after equalization, then playback loudness can be balanced, but user experience deteriorates due to additional manual operations
Solution Approach 1:
The system performs preliminary volume adjustment by determining a volume adjustment value based on the volume adjustment type and current playback attribute information before playback occurs. This preliminary action ensures that the volume is pre-adjusted to appropriate levels, eliminating the need for manual adjustment during playback and improving ease of operation while maintaining reliable loudness balance
Solution Approach 2:
The system enables self-service by automatically determining volume adjustment types and calculating volume adjustment values without user intervention. The playback terminal autonomously adjusts the initial volume of media data based on its own playback attributes and the determined volume adjustment type, making the system self-regulating and eliminating manual operations
2Measurement precision
If volume adjustment value is determined based on playback attribute information, then volume adjustment accuracy improves, but system complexity increases
Solution Approach 1:
The system performs preliminary determination of volume adjustment types and pre-calculates volume adjustment values based on playback attribute information before actual playback. This preliminary processing organizes the complexity in advance, allowing the system to achieve precise volume adjustment by referencing pre-determined values during playback without requiring complex real-time calculations
Solution Approach 2:
The system introduces intermediary elements including volume adjustment type classification and volume adjustment value calculation as intermediate steps between the raw playback attribute information and the final volume adjustment. These intermediaries break down the complex adjustment process into manageable stages, improving measurement precision while organizing system complexity into structured components

AI summary
The present disclosure discloses a method of adjusting volume, an electronic device, and a non-transitory computer-readable storage medium. The method of adjustment volume includes: acquiring media data to be played; determining a volume adjustment type corresponding to the media data to be played; determining a volume adjustment value based on current playback attribute information of a playback terminal that plays media data and the volume adjustment type, in which the volume adjustment value is configured to adjust an initial volume of the media data to be played; adjusting the initial volume according to the volume adjustment value; and playing the media data to be played based on an adjusted initial volume.
