EVALUATION OF NTH BIT REPLACEMENT IN AUDIO STEGANOGRAPHY

Audio Steganography is well known technique of hiding secrete text or audio information in host audio by modifying an audio signal in an imperceptible manner. Least Significant Bit (LSB) is the most commonly used technique for secure data transfer in audio steganography. The present paper focusses on nth bit replacement to hide a sequence of bytes of secret text and comparing the MSE and PSNR of SteganoAudio for all the bits.
