In previous years, existing research has been taken for hiding secret data into digital audio signal because of advantages of psycho acoustical masking phenomenon of human auditory system [HAS]. In this review paper a novel approach based on audio steganography by integrating optimal steganography and two level cryptographic methods. Improvement of imperceptibility of data hiding and increased security level for the secret data has been provided. Audio Steganography is the procedure of hiding the existence of secret information by zipping it into another medium such as audio file. In our system the innovative audio Steganography technique in a practical way in order to conceal the preferred information. The proposed system uses LSB (least significant bit) technique for embedding audio secret data into image cover data. We also try to other steganography techniques in our system.
