Method of Audio Signals Watermarking Based on the Wavelet and Fourier Transforms

摘要

The spectral approach to building systems with digital water marks (DWM), based on the characteristics of human hearing, and the analysis of effect of typical audio processing operations upon the audio spectrum, is considered. The new method and algorithm for permanent audio signals marking on the basis of fast wavelet transform and fast Fourier transform is proposed. The testing on intangibility and robustness of DWM embedded was carried out.
