摘要：There are many techniques existing for watermarking. Among all of the known techniques Fibonacci isthe advanced technique for digital audio watermarking. In previous paper, we can observe that Fast Fourier Transformis used for embedding data and extracting them into bit extracting manner by changing the magnitudes of the FastFourier Transform spectrum. In this paper, discrete wavelet transform is used for watermarking. By using discretewavelet transform we get better resolutions when compared to the previous techniques. The main advantage of usingFibonacci numbers is that it is possible to change the frequency samples adaptively. This paper focuses mainly onreducing the number of bits that are used for embedding and extracting. The results show that the method has highcapacity and without any distortions in the audio signal and also provides robustness to the common digital audio signalprocessing.
