A spectograph !
I think it didn't exist in flowstone, and i think i understand why !
It's very not easy to do for some reason.. Data conversion ...
Break my head about it from some time.. Trying then re-trying and re-trying..
So it's not perfect but seams to works. Don't hesitate to upgrade or suggest it if you have any idea !
Limitation are : Size is not configurable; Slow to refresh; Fixed size 1.5second;
Also it only measure every note and half note from 27.5 to 22050. It's not fft nor bandpass. Those would maybe slow more or add additional latency in the measure. Here the module send every frequency then catch the result from the analyzer. Paint a line measuring volume with 512 hop. Then go for the next line and frequency..
Maybe some faster tick would be great..
(edit: for an fft the problem is also the precision in bass, would need very big fft for decent precision, and reverb generally add more problem with bass than anywhere attenuating to much some frequency...)
Anyway i'm happy to have some result. So many time i wanted this to see what happen for frequency along time..
But would be cool if it could be perfected..
