摘要：This work is related to audio Stegnography and presents the statistical analysis of various quality measuring parameters of audio Stegnography, e.g. signal to noise ratio (SNR), peak signal to noise ratio (PSNR) and mean square error (MSE), for different bit position substitution in an audio cover file in discrete cosine transform (DCT) domain. Interestingly the resulted mean square error (MSE), signal to noise ratio (SNR) and peak signal to noise ratio (PSNR) for each bit position shows a very insignificant variations in the values of the quality measuring.
