Is it possible to encode audio in the form of images , which is read by the camera and is played in real time?Comes to mind QR- code or some of its counterparts. In such a code can be written reference to mp3, or even a very small audio file. But
in the first case requires access to the network , while the second - a
high density of code, and increased demands on the quality of the image
. Furthermore, neither the one nor the other way will not provide instant replay .If no sound is encoded in a digital and analog format ? That is, to prevent the possibility of large loss of information while preserving the basic " shape " of the sound message. For example, such losses occur in poor lighting , poor camera , a small picture , wrinkled, or torn paper with the code. Let with terrible artifacts , but the picture is supposed to sound .
For several years I have been studying the Soviet photoelectron ANS synthesizer created by engineer Evgeny Murzin in the period from 1938 to 1958 Synthesizer based on earlier technology so-called " drawn sound ", more details of which can be read, for example , in this article or online Generation Z. The chip also ANS is that music is created by drawing a spectrogram and then played some semblance of modern scanner - a vertical scanner shines score by projecting light on special wheels ( kinda Fourier optical transducers ) who are willing to send the modulated signal by photocells . This format is ideally suited to a sound recording in a graphical form . Damaged or reduced spectrum may lose some harmonics , but will retain the overall picture for later playback. And very handy I established a software simulator of the ANS synthesizer - Virtual ANS, can not only play such scores, but also to create , converting an audio file on the image spectrum. What you need !It remains to answer the last question - how to mark the border Pictures, anti-virus scanner to play exactly what you need without taking up extra information . It was decided to use only the horizontal top and bottom handles . Failure of the code markers at the sides , first, the decoding process easier , and secondly allows inexpensively spectrogram play immediately after the detection of the horizontal markers. In this case the process can be operated manually play : speed and direction sets himself listener freely scanning image . Manual mode is fascinating but uneven movement and shaking hands leave their imprint on the sound. Therefore, the program should be added and the automatic mode when the current frame from the camera freezes and uniformly scanned without user intervention.Give the name of the project PhonoPaper. Specification code is as follows :
