Steganography is a branch of cryptography, which literally means \"Hidden writing\", is about hiding the existence of a message inside text, images, audio, video. Audio as a cover medium in steganography has its own place due to its bigger size compare to other carrier's file like (text, image, etc.). So the people can hide large amount of data inside audio as a cover. Steganographic algorithms can be characterized by a number of defining properties like transparency, capacity, robustness. In this paper, the authors will survey the general principles of hiding secret information using audio technology, and provide an overview of current functions and techniques.
