Steganography is a technique which is used to hide audio signal behind an image in the transform domain using wavelet transform. The audio signal can be of any type, any format like MP3 or WAV or any other type is encrypted and hide behind an image without disclosing even the existence of audio signal to anyone. It gives the best way to send an audio signal by hiding the secret data.
