In analog.cpp I read in the comments:
”...the coefficients below are found by windowing the inverse DFT of the 1024 pin frequency response converted to the minimum phase..."
Can somebody explain what does "1024 pin" means ? Maybe he rather means "bins" ?
But my point is: how can you compute the freq resp of the hardware analog part, since we can't generate a single sample pulse via software ? Even by setting a very short adsr (lev1=100, lev2=0, t1=0, t2=0) you still can't generate a single sample pulse from eg. a square wave or pcm wave... Maybe the IR was sampled by feeding physically an external short pulse ? I think that, not being able to generate a pulse by software, any attempt to guess the real IR will always be a rude approximation. Or I am so wrong ? Thx
