Information hiding is a part of information Security. Steganography is a technique of information hiding that focuses on hiding the existence of secret messages. The aim of steganographic methods is to hide the existence of the communication and therefore to keep any third -party unaware of the presence of the Steganographic exchange In our project we will implement an algorithm to hide text messages in audio signal which can be used for message communication and will decoded at other user end with the decoder software designed with inverse of algorithm to decode messages from audio file send. Embedding secret messages into digital sound is known as audio Steganography. It is usually amore difficult process than embedding messages in other media. Audio Steganography methods can embed messages in WAV, AU, and even MP3 sound files.
