Audio Signal Analysis via Dynamic Feature Vector Configuration

The patent implements dynamic configurability of feature vectors through a parameter-based architecture. The feature extractor is designed to accept configuration parameters that define the structure and content of feature vectors, allowing the system to adapt to different applications by changing parameters rather than rewriting code. This enables the same core system to generate different feature vector formats dynamically based on application requirements.

The system uses parameter changes to control feature vector characteristics. By modifying parameters such as window size, feature types, and extraction methods, the system can adapt to new applications without structural changes. The configurable parameters allow flexible adjustment of feature extraction behavior to match specific application needs while maintaining the same underlying system architecture.

The patent creates a universal feature extraction framework that can perform multiple functions through configuration rather than custom coding. The second-stage feature extraction is designed as a configurable module that can be adapted to different applications by setting parameters rather than writing new code. This universal approach allows the same extraction logic to serve multiple applications with different requirements.

The system uses template-based configuration where common feature extraction patterns can be copied and reused across different applications. Instead of custom-coding each extraction process, pre-defined templates can be instantiated with different parameters for new applications, significantly reducing development effort while maintaining application-specific precision.

The patent segments the audio processing system into distinct modular components: feature extraction, data mining, and application processing. Each component can be independently configured and replaced, allowing run-time adaptability. The segmentation enables different combinations of components to be used for different applications without redesigning the entire framework.

The patent introduces an intermediary layer between the processing components and application environments. This intermediary handles configuration management and integration logic, allowing the core processing framework to remain simple while providing run-time configurability and broad integration capability through standardized interfaces.
