A project for Data Communications by Derek Girardi during the fall 2012.

This project was begun on 12/10/12 and is anticipated to take 1 day.

I want to see if i am able to put music data inside image data! I just want to see if the difference in data matters when the two are intertwined.

In order to successfully accomplish/perform this project, the listed resources/experiences need to be consulted/achieved:

• Linux
• Command Line
• Knowledge on data
• File formats

This project is just something fun to do. When you hide music inside a photo, you wont actually hear it at first. But once you see the photo in a mp3 player, the audio will start playing. The purpose of doing this is to see if i can do it! I just want to see how simple or how complex it can be putting music literally inside a photo. I just want to see it done and you will through this project!

I am just going to run through the steps of doing it and show the code on the command line of how i got there!

Step 1: Find a picture and some small audio clip you want. I will personally probably be using nyan cat audio with a nyan cat picture because i want to and yea. Any picture and or gif can be used, they will all work. (See figure 1)

Step 2: The picture i found was way too big so i issued the command mogrify -resize 640 *.png which will convert the photos in the folder into a smaller image. It should still be able to hold an audio file.

Step 3: Next i will put the audio right into the picture to create our final music picture! (see figure 2)

Step 4: If everything works out, try it out! click on it and see if it opens up your mp3 player or whatever you may be using.

This project can definitely be taken farther, i just wanted to see how it could be done and well, it can! More can be done though…
