Hi there, i read close to 24h in this thread and done some testing with the basic audio files where this gif was made of:
http://rsln.net/random/data-anim-hires.gif
I have found some points that are really interesting for me:
1.) Why were always only the Frequenzrange of the hearable Soundrange checked?
2.) Everyone sees the 4 Markers @ the circle but why are they at these points at the grafic?
3.) Does anyone of you know a kind of writting where you write in an X-style? I mean in english we start at the top left write to the right and than the next line but here it looks different.
4.) What the Spektrumgrafic shows us depends strongly by the frequenz filters used but if you compare the Spectrumgrafic with waveform signal of the audio you can see some points where are Datas in it. Befor and after the circle.
5.) Think of with the Arecibo-Message send to Space by Mankind. Remember the prime numbers. Here we have 23 and 41 bothe are prime numbers. So we could read the databits.
6.) I would check the long audiofile for some data points or something like that, but i just can listen to it atm. So if anyone of you have the audiofile please let me know how i can get it for some testing.
7.) Did anyone tryed out to remove the noise shadow in front of the main grafic in spektrum. you can see it in the gif, if you look only at the thing that don´t change.
8.) For me is the Grafic not only 1 key, the complete grafic is at min. 2 Keys for me or maybe more.
For the moment that is all i could find out with my friends and now i try to rest a bit, because more than 24hours of work are more than engouh.
I hope that my thinking of the grafic and codes will help you and i will try my best after some rest.
Good luck and please find the code.
