• format of graphical representation of the sound (music, human voice, etc.); in other words, it is the 2D audio barcode (by analogy with the QR-code);
• real-time PhonoPaper-code reader (using the camera);
• PhonoPaper-code generator (sound to image converter).
• 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;
• PhonoPaper does not require access to the network; its code is self-contained;
• PhonoPaper-code can be played in real-time with hand-controlled speed and direction;
• PhonoPaper-code can be drawn by hand (paper version of the Virtual ANS synth);
• PhonoPaper is free!
Examples of usage:
• voice messages (or pieces of music) on the billboards, posters, postcards, goods;
• audio labels for phonorecords;
• audio examples in some textbooks;
• learning the basics of the spectral music.
PhonoPaper is based on the Virtual ANS engine - it is a software simulator of the unique Russian synthesizer ANS. So if you want to make more complex PhonoPaper-codes - use the Virtual ANS: http://warmplace.ru/soft/ans
Default PhonoPaper-code length is 10 seconds. But you can make it shorted or longer - playing speed can be changed manually.
Known solutions for some problems:
* compressor has been added to the audio engine;
* bugs fixed.
