With the growing trends in wireless network in this modern era, more and more multimedia data are generated and transmitted. So the effective ways to ensure their security are increased. This can be achieved by implementing steganography techniques. Audio steganography is more challenging compared to image or video steganography. There are number of audio steganography methods. In this paper, the authors focus on different wavelet families for embedding secret message in audio file. The advantage of wavelet is due to its reconstruction property and its capacity of capturing the low frequency component.
