Whenever we talk about secret information, then in that case confidentiality plays a vital role in between
communicating parties. Cryptography and Stegnography are the two main pillars of information security. Cryptography is
used just to scramble the information by apply various algorithm e.g Deffie - Hellmen etc, but it is able to reveal secret
information: that eavesdropper will come to know that this specific information will contain some confidential data.
But Stegnography is completely opposite to it. It simply hide the content, In it only sender and receiver will come to know
about the confidential information. Now, in this research article We will show that how an audio message will secretly
hides confidential data and send it over a medium without a man in the middle will come to know about it: by using
Coagula by sender to embed the message in audio and Sonic Visualizer by receiver for decoding purposes. The message
which is to be send it can be audio, video, text, image and etc, but here we concerned about image which contain secret
information. When image is embed in audio signal then it become stego-signal. In it quality of audio does not suffer
because quality is checked twice before and after the extraction of secret message. Quality of stego-image is measured by
peak signal to noise ratio(PSNR), Structural Similarity Index Metric(SSIM), Now extracted image is measured by Signal to
noise ratio(SNR) and Squared Pearson correlation coefficients(SPCC). Both the quality measures will show good results.
