Detailed Documentation

This program implements an echo cancellation algorithm designed to effectively remove echo interference from signals. The implementation utilizes sophisticated mathematical operations and digital signal processing techniques to analyze and process incoming signals. Key algorithmic components include adaptive filtering using NLMS (Normalized Least Mean Squares) algorithm and cross-correlation analysis for echo path estimation. The code features detailed inline comments explaining each processing stage - from signal preprocessing and buffer management to filter coefficient adaptation and residual echo suppression. By employing real-time filter adjustment mechanisms and spectral subtraction techniques, users can achieve enhanced signal clarity and stability. This implementation improves data processing accuracy by dynamically modeling echo paths and applying inverse filtering, making it suitable for telecommunications and audio processing applications where signal purity is critical.
