In the last decades, Because of great development of communication in the world today, the digital watermarking has loudly proclaimed as a new method to improve communication security and control. The process of steganography is available on the host signal. In this paper, a new method of file steganography with WAV format is presented. Thus, it is designed according to spread spectrum techniques and CHIRP signal. The proposed method is completely compatible with WAV compressing standard and creates a hidden link between the sender and the receiver and accordingly the SNR will be noticeably decreased. The experiments indicate that our proposing algorithm guarantees the imperceptibility of watermarking, as well as high capability of operation and security against attacks.
