An Audio Watermarking Algorithm using Encryption, Transformations and Quantization

The central idea of this paper is to propose a robust audio watermarking algorithm using statistical parameters and energy of the signal in the discrete wavelet domain and also using discrete cosine transform. The performance of the algorithm is provided by evaluating the performance parameters such as signal to noise ratio, normalized correlation, and bit error rate. In addition, the effects of the quantization types such as single value quantization and mean quantization on these components are provided.
