Engineering Contradiction Analysis
1Reliability
If conventional audio signal processing techniques are used, then noise suppression is provided, but the performance is inconsistent across different applications and audio output modes
Solution Approach 1:
The patent implements dynamic selection of audio signal processing operations based on the specific application and audio output mode. The system evaluates multiple processing operations and selects the most appropriate one in real-time according to the current usage scenario, transforming the static conventional approach into a dynamic adaptive system that maintains consistent performance across different conditions
Solution Approach 2:
The patent changes the parameter of processing operation selection based on application type and audio output mode. By evaluating multiple candidate operations and selecting the optimal one for each specific scenario, the system adapts processing parameters to match different usage conditions while maintaining reliable performance
2Measurement precision
If multiple audio signal processing operations are evaluated and selected based on signal similarity, then the most appropriate processing operation is chosen for specific applications and output modes, but the processing complexity increases
Solution Approach 1:
The patent performs preliminary evaluation of multiple audio signal processing operations by comparing processed signals with primary signals to determine signal similarity. This pre-evaluation process identifies the most appropriate processing operation before actual audio processing, enabling accurate selection without increasing real-time processing complexity
Solution Approach 2:
The patent uses synthesized audio signals as copies to evaluate processing operations. By creating synthetic test signals that represent different scenarios, the system can pre-evaluate multiple processing operations and select the best one without requiring complex real-time analysis during actual audio processing
