An Embedding of Secret Message in Audio Signal

The steganography is the embedding process of the secret message in the other carrier message. It carries the security, transparency and authenticity. The type of steganography is depends on the cover message used, if cover message used is audio to hide any type of data, it is audio steganography. The secret data hidden behind the audio can be image, audio or text. Audio steganography is more preferable because of the lots of redundancy. The different domains and methodologies are in exist for secret data embedding in audio signal. This paper gives the variety of algorithms to study the Audio Steganography.
