Audio Playback Compensation Using Spectrum-Matched Filter Sets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio processing methods require repeated adjustments to equalizers, leading to inefficient audio playing effects, as users must listen to changes and adjust again, making the process time-consuming.
Innovation Solution
An audio processing method that determines a matching rule by analyzing the frequency spectrum difference between a reference audio and an audio to-be-matched, using this rule to compensate the audio playing device, thereby improving the audio playing effect efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the equalizer is adjusted manually by listening repeatedly, then the audio playing effect can be optimized, but the adjustment process takes a long time and has low efficiency
Solution Approach 1:
The patent pre-calculates and stores optimal equalizer parameters for different audio files based on their frequency spectrum characteristics before playback. When a user selects an audio file, the system directly retrieves and applies the pre-computed parameters without requiring real-time manual adjustment, thus achieving high-quality audio optimization instantly without time-consuming iterative listening and adjustment
Solution Approach 2:
The patent replaces the manual mechanical adjustment process (listening-evaluating-adjusting-repeating) with an automated computational system that analyzes frequency spectrum data and calculates optimal equalizer parameters algorithmically. This substitution of mechanical human operation with automated signal processing achieves both high precision and time efficiency
2Manufacturing precision
If the equalizer parameters are adjusted frequently to achieve desired audio effect, then the audio quality improves, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent enables the audio processing system to automatically analyze the frequency spectrum of each audio file and self-determine the optimal equalizer parameters without user intervention. The system serves itself by computing and applying the appropriate audio effects automatically, eliminating the need for users to perform complex manual adjustments while maintaining high audio quality
Solution Approach 2:
The patent automatically changes equalizer parameters based on the frequency spectrum characteristics of each audio file. By dynamically adjusting parameters such as gain at different frequency bands according to the audio content's spectral profile, the system achieves optimized audio quality without requiring users to understand or manually adjust multiple parameters

AI summary
Implementation of the disclosure provides an audio processing method, a device, a terminal and a computer-readable storage medium. The method can include the following. An audio to-be-matched and a reference audio are obtained. A frequency spectrum distribution of the audio to-be-matched and a frequency spectrum distribution of the reference audio are obtained. A target filter set for matching the audio to-be-matched with the reference audio is determined according to the frequency spectrum distribution of the audio to-be-matched and the frequency spectrum distribution of the reference audio. The target filter set is determined as a matching rule for the audio to-be-matched and the reference audio. An audio playing device is compensated by using the matching rule to adjust an audio playing effect of the audio playing device; and an audio is played through the compensated audio playing device.
