PhonoPaper is a camera app for enjoying photos with encoded sound (PhonoPaper-codes).

With this app, you can also create your own codes: 10 seconds of sound could be recorded from a microphone and converted into an image.

Key options

* PhonoPaper doesn't require access to the network for decoding;

* PhonoPaper code is analogue, so it's not so sensitive to various sorts of the picture distortion (bad camera, darkish picture, wrinkled paper, etc.); at least you'll hear the silhouette of the original sound;

* code may be played in real-time with hand-controlled speed and course;

* code can be drawn by hand to get some uncommon 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, level the camera at the code (tap on the display to focus if necessary) and easily scan the image from left to right. The code should be parallel to the body - try to maintain the digital camera stage. The black code markers (top and bottom) should fall completely into the body. If the applying recognizes code markers, you'll hear a sound. If you're unable to play the code easily, press the report button on the right facet of the display, this will enable automatic scanning.

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