Steganography is an art and science of writing hidden messages in such a way that no one apart from the intended recipient knows the existence of the message. The maximum number of bits that can be used for LSB audio steganography without causing noticeable perceptual distortion to the host audio signal is 4 LSBs, if 16 bits per sample audio sequences are used. The authors propose two novel approaches of substitution technique of audio steganography that improves the capacity of cover audio for embedding additional data.
