Abstract
This paper describes a method for achieving audio steganography through spectrum modification of the cover signal- the signal into which the useful and valuable information is embedded. The embedded data signal is inserted into the regions of the cover signal spectrum where power of frequency content is low. Also the level of the embedded signal is kept low enough inorder to avoid the crossing of thresholds for audio perception. By performing these steps, the data signal shows no trace of being embedded in the cover signal. This method of audio steganography can be used to robust covert communication.
