Video to Audio Converter

With a little script, I successed converting binary file to audio spectrum, and another software called Photosounder changed spectrum to sound.

Left signal:

Right signal:

Note: memory basic limitations only allowed me to make a 25000×128 px image, I’d need about 22.937.600×128 px image for a whole film!

Audio spectrum will look like the two previous pictures. We’ll take care not to include signal in weak frequencies (cracks, whistles…), and try to keep low ones for best reliability.

Both signal are 128-bit encoded, to bring 256-bit data at once! bits are buffered and a video strem client (eg: VLC) vill read it to display movie.

It’s important to note that 1:30 film will fit on a 30 min LP side, so most film will be stored in buffer memory…

Calculus: 256 bits * 10000 Hz = 2 560 000 bits / sec = 550 MB on a 30 min side!
