Hello,

I am the developer of a software ( CineToVidPro ) which allows to scan cine films (8 mm or 16 mm) with a standard flatbed scanner and to convert them to mpeg files that can be played with a standard DVD player ( e.g. VideoLan).

Normally the sound is recorded on this kind of films on a magnetic sound track, but recently I got the request to find out, if light sound tracks of Regular 16 cine films could be converted automatically.

To scan the recorded sound track would be no big problem. But I have no Idea how to convert the track image into a digital file (e.g WAVE) that could be played by a media player.
It is also no problem to extract the width of the sound track at certain position (e.g. every 1/12000 sec) and record the found values as digits in a file.
But how to get there from this digits to a sound.
It is obviously the opposite what is done with a wave file to show the sound visually ( in CDEX or other sound editors e.g. Audacity).

Has anybody an idea, how to transform the series of digits to make a WAVE file from them that c can be played, I think it is necessary to add a specific file header and a time code or other things.

Any assistance would be highly appreciated.
My dream would be something, that can be imported to e..g. CDex and would be accepted as an audio file scan.
