Abstract:-As a review of this paper present a novel method for digital audio steganography
where encrypted covert data is embedded by DWT based and LSB based. 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. Data hiding, a form of steganography, embeds data into digital media for the
purpose of identification, annotation, and copyright. Several constraints affect this process: the
quantity of data to be hidden, the need for invariance of these data under conditions where a
“host” signal is subject to distortions
