Hiding information is an art and science of communication technology. Using Steganography information can be hidden within other information that it cannot be detected, but only by its intended recipient. Now a days for hiding information there are different multimedia systems like audio etc. Embedding secret message in sound is a difficult process. There are varying techniques for embedding information in audio. In this paper we will attempt the general principles of hiding secret information using audio techniques and an overview of its functions.
