That means cyclone's allpass~ is not done properly. Why not do it the standard and more efficient way? When it comes time to do dozens of allpasses it will make a difference.On Sat, Oct 5, 2013 at 1:00 PM, Alexandre Torres Porres <porres@gmail.com> wrote:
but this way it won't be the same as cyclone's [allpass~], the way I did it is equivalent to it (and max's).cheers2013/10/3 Chris Clepper <cgclepper@gmail.com>You only need one delay line for the allpass.feedforward = input * -gainfeedback = delayout * gaindelayin = input + feedbackoutput = delayout + feedforwardOn Thu, Oct 3, 2013 at 11:29 AM, Alexandre Torres Porres <porres@gmail.com> wrote:
i hope i guess i figured it out on how to implement it with delay lines. see attachment. And I realize you can't do this with [fexpr~] or [biquad~] because the sample delay length is kinda big for that, right?cheers2013/10/3 Alexandre Torres Porres <porres@gmail.com>
cool, but do you know how to implement cyclone's [allpass~] with it?It's really unclear to me what is the relation of this pass filter with the one you can generate with biquad coefficients, or with raw poles/zeros objects for that matter.Well, one way or another, it's also unclear to me how to do it with delay lines.seems that it is related to a comb filter, right?cheers2013/10/2 Chris Clepper <cgclepper@gmail.com>
Allpass for reverb is easy to do with delwrite~ and vd~. I used 32 of them today to recreate a famous 'deep space' reverb.On Wed, Oct 2, 2013 at 1:53 AM, Alexandre Torres Porres <porres@gmail.com> wrote:
_______________________________________________hi there, i see the biquad's coefficients can be set as an allpass filter, generated by frequency and "Q" parameters. But can it do the same as cyclone's [allpass~] filer? If yes, them how since the parameters for [allpass~] are different (delaytime and such).One way or another, I guess that my real question is: how to implement [allpass~] from vanilla objects?thanks
