Audio Watermark Embedding Program with BCH Encoding

This program performs BCH encoding on audio signals followed by watermark embedding. The implementation involves processing audio signals through BCH encoding algorithms and then embedding watermark information into the encoded signal structure, thereby enabling audio content protection and authentication. The watermarked audio signals can be transmitted and stored without compromising original audio quality, while the embedded watermark can be extracted using corresponding decoding algorithms for verification purposes. The design methodology leverages BCH codes' robust error-correction capabilities combined with the stealth properties of watermark embedding techniques. Key implementation aspects include: BCH encoding parameters configuration for optimal error correction, discrete wavelet transform (DWT) for audio segment analysis, and amplitude modulation techniques for imperceptible watermark insertion. The algorithm ensures watermark resilience against common audio processing operations while maintaining audio fidelity. This solution addresses information security requirements by providing a reliable audio watermarking technology that balances detection reliability with minimal perceptual impact. The code structure typically includes modules for audio preprocessing, BCH encoding/decoding functions, watermark embedding/extraction routines, and quality assessment metrics calculation.
