Hi there, as I've been saying here, I've been studying about filters and trying to emulate some of the filters as raw filters, or in biquad coefficients.
I thought I had nailed [bp~], but now it seems there's some minor discrepancy between the original object and my patch implementation. Check the test patch I made:
https://docs.google.com/file/d/0B3AoiT0xk8fnWmhuYWtPdk9UYUU/edit
I'm analysing a filtered noise with [env~] and the resulting numbers should match exactly in order to prove I've done it right, but a small difference in value insists on showing up.
Would any of you be interested in checking it up? Maybe you can find some mistake that could be corrected and then match the numbers perfectly, or maybe you could tell me why there's such a small difference and it'll always be there... I don't know. I have the full code in the patch for you to check it out.
All I know is that I've done the same thing with lop~ and numbers match beautifully
By the way, [vcf~] is next on my list
Thanks! cheers
