Abstract:-Steganography may be a technique for hiding data in a host signal. The host signal
may be a still image, speech or video and therefore the message signal that's hidden within the
host signal can be a text, image or an audio signal. For data hiding in acoustic, discrete cosine
transform (DCT) and discrete wavelet transform (DWT) both are used. Perfect audio
Steganography technique aim at embedding data in an imperceptible, robust and secure way and
so extracting it by authorized people. Hence, up to this point the main challenge in digital audio
steganography is to get robust high capacity steganography systems. Leaning towards designing a
system that ensures high capacity or robustness and security of embedded data has LED to great
diversity within the existing steganography techniques. In this paper, we tend to present a existing
position of art literature in digital audio steganography technique. In this paper a completely
unique methodology for digital audio steganography someplace encrypted concealed data is
embedded by adaptively modifying wavelet packet coefficients of host audio signal. Steganography
is an information hiding technique where secret message is embedded into unsuspecting cover
signal. Measuring of fine steganography algorithmic rule includes security, capacity, robustness
and imperceptibility
