Sounds very interesting. What did you add to your .wav file? Can you upload an example, so I can see how to explain?

I am using least significant algorithm for watermarking in audio signal.

The watermark here is text (e.g sushain )and audio signal is

any wave stereo file. Each time i increase the number of characters both PSNR,SNR of audio signal improves. improves.
