neotec: i still don't fully understand this voodoo here
your 1st order LP/HP filters use a "fixed" sample prediction which is of 1 iteration at all times?
while the other post proposes the iteration method..
got lots of questions and i still don't get how this works exactly
1) your HP and LP filters, what can be done with them? can they be added together to form a cascaded filter? i guess yes, but then, i think feedback from the last stage to the first won't work without extra code, right?
2) the iterative method - filter buffers you mean the memory? x1 y1 y2 and so on, right?
as far as i understand, for each sample, you use a temporary "filter"
you copy the memory variables from the original filter
then you process 1 sample with the temporary filter, but you don't let it store what it usually has to store in it's memory buffers
then you check it's output..
at first i thought you process with a temporary filter, but i didn't notice you reset the memory every time, and i thought it would begin to resonate (depending on parameters) which seemed to not make sense..
but now it looks like you're processing the thing but NOT letting it resonate, this does make a bit sense if i'm right..
it still amazes me, how can you "predict" the output, my brain simply shuts down
It doesn't matter how it sounds..
..as long as it has BASS and it's LOUD!
