About this app

PhonoPaper is a camera app for playing pictures with encoded sound (PhonoPaper-codes).
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.

[ Key features ]
* PhonoPaper does not require access to the network for decoding;
* PhonoPaper code is analogue, so it is not so sensitive to different types of the image distortion (bad camera, dark picture, wrinkled paper, etc.); at least you will hear the "silhouette" of the original sound;
* code can be played in real-time with hand-controlled speed and direction;
* code can be drawn by hand to get some unusual sounds.

[ Examples of usage ]
* voice messages (or pieces of music) on t-shirts, billboards, posters, postcards, goods;
* audio labels for phonorecords;
* audio examples in books;
* secret messages;
* art-experiments.

[ How to use ]
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. 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. 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.

Default PhonoPaper code length is 10 seconds. But if the code was generated in Virtual ANS app, its length can be much longer - in this case, the playback speed can be changed manually.

Only just begun to play with this, but I really love the concept of this app in every way. A graphic depiction of the sounds the device hears printed in sonar waves. You can replay them by scanning over the image. I wonder how well a tattoist worth his salt could replicate this type of graphic depiction of audio. The idea has endless possibilities. I would love to give an extra star 🌟 just for uniqueness.

This is possibly one of the coolest apps ever. One really fun thing to try is to say a small phrase, make a code of it, and then try to copy the shapes on blank white paper with a soft pencil. Even if your shapes are not anywhere near exact, you can make alien voices come out of your phone from pencil marks on paper! Amazing!

Outstanding but should not be free. This is pure wisdom an should be selective. Also, creators need to have better instructions on how to use the app(s). Please fix the sound issue when you click the start button to free scan images, an the static sounds turn on, sometimes it's extremely loud and it is very annoying and has hurt my ears few times using headphones. Please have sound disabled with warning an a check box saying turn volume down and adjust accordingly or something similar.
