Abstract :
This paper proposes an audio watermark embedding and extraction algorithm based on fast Fourier transform (FFT). This algorithm makes full use of human auditory system (HAS) characteristic, embeds watermarking information into the phase coefficient of audio signal after FFT. The experimental results show that the audio watermarking generated with the proposed algorithm are inaudible and robust characteristics against noise and commonly used in audio processing techniques.
