On the rise of the Internet, digital data became openly public which has driven IT industries to pay special consideration to data confidentiality. At present, two main techniques are being used: Cryptography and Steganography. In effect, cryptography garbles a secret message turning it into a meaningless form; while, steganography hides the very existence of the message by embedding it into an intermediate such as a computer file. In fact, in audio steganography, this computer file is a digital audio file in which secret data are concealed, predominantly, into the bits that make up its audio samples.
