Digital Watermarking for Speech Signals Using LSB Algorithm Implementation

This project implements digital watermarking for speech signals using the Least Significant Bit (LSB) algorithm. The implementation includes comprehensive code comments and supports various audio signal formats. By embedding watermarks into speech signals, this technique enables audio content protection and authentication. The algorithm demonstrates excellent robustness and imperceptibility, effectively resisting various attacks and noise interference. Key implementation details include: - Processing audio samples by modifying the least significant bits of audio data - Maintaining audio quality while embedding watermark information - Providing configurable embedding strength parameters - Supporting both watermark insertion and extraction functions Through this algorithm implementation, you can achieve enhanced security and reliability in applications requiring audio data integrity protection and copyright management. The code structure includes modular functions for audio preprocessing, watermark encoding/decoding, and signal analysis.
