Abstract: Recently, information-hiding techniques have become important due to the widespread use of multimedia and the Internet. Actually, information hiding falls into two large categories: steganography, which is the art and science of secure communication, and watermarking, which is used to protect copyright and data ownership. Audio has some unique features that have motivated many researchers and developers to use it as an information-hiding medium. The audio, referred to as cover audio, is used to conceal a secret message, making it unnoticeable to the observer due to steganography techniques. This paper reviews audio steganography techniques and classifies them scientifically. The strengths and limitations of each steganography technique are presented in this work, moreover, it shows how the researchers treat the weaknesses of each method. The paper highlights an audio steganography emerging challenges such as advanced hiding methods and real-time steganography systems which have special constraints discussed in this paper. Audio steganography can utilize cover audio in various domains, which we have compared in our work, along with a comparison of steganography techniques. Subjective and objective quality measurements of audio steganography are depicted in this paper
