Abstract :
The paper proposes a combination of audio watermarking algorithm based on the wavelet transform and the Fourier transform. After the binary watermark image pre-processing, wavelet transform is taken for the audio, then the discrete Fourier transform is taken for the wavelet transform approximation component coefficients. Finally the amplitude of the Fourier transform coefficients is quantized to embed the watermark. In the watermark extraction process, the original audio signal is not require. This paper describes the detailed process. At last, the simulation tests confirm the robustness and transparency.
