With this app, you can also create your own codes: 10 seconds of sound can be recorded from a microphone and converted into an image. * diese App code is analogue, so it is not so sensitive to different types of the image distortion (bad camera, dark picture, wrinkled paper, etc. * code can be drawn by hand to get some unusual sounds.  Launch the app, point the camera at the code (tap on the screen to focus if necessary) and smoothly scan the picture from left to right.  If you are unable to play the code smoothly, press the record button on the right side of the screen, this will enable automatic scanning.  The code should be parallel to the frame - try to keep the camera level.  The black code markers (top and bottom) should fall entirely into the frame.  If the application recognizes code markers, you will hear a sound.  diese App is a camera app for playing pictures with encoded sound (diese App-codes).
