hi!
i'm currently building a stereo vocoder in radium's faust development
environment, and i've run into a minor problem
i have the core vocoder running, but i can't figure out how to route the effect
input the way i want to. i'd like to have input 1 going into the left channel
modulator input, input 2 going into the right channel carrier input, and inputs
3 and 4 going into their respective modulator inputs. but as of now inputs 1
and 2 are routed to the left channel unit and inputs 3 and 4 are routed to the
right channel input
hopefully this makes sense. here's my faust code (don't mind the fact that some
code is ripped from the libraries):
import("stdfaust.lib");
select4(s) = *(s==0),*(s==1),*(s==2),*(s==3):>_;
n = 8;
mod_order = nentry("modulator
order[style:menu{'-12db':0;'-24db':1;'-36db':2;'-48db':3}}]",0,0,3,1);
mod_bw = vslider("modulator bw",0.5,0.1,2,0.001);
car_order = nentry("carrier
order[style:menu{'-12db':0;'-24db':1;'-36db':2;'-48db':3}}]",0,0,3,1);
car_bw = vslider("carrier bw",0.5,0.1,2,0.001);
bp(freq,q) = fi.svf.bp(freq,q);
multi_bp(freq,q,order) =
_<:bp(freq,q),(bp(freq,q):bp(freq,q)),(bp(freq,q):bp(freq,q):bp(freq,q)),(bp(freq,q):bp(freq,q):bp(freq,q):bp(freq,q)):>select4(order);
voc_band(band_num,bands_num,bw_ratio,order,bg,x) = x : multi_bp(band_freq,
band_q, order) : _*bg with {
band_freq = 25*pow(2,(band_num+1)*(9/bands_num));
bw = (band_freq - 25*pow(2,(band_num)*(9/bands_num)))*bw_ratio;
band_q = band_freq/bw;
};
voc(bands_num,att,rel,mod_bw,mod_order,car_bw,car_order,carrier,modulator) =
carrier <: par(i,bands_num,voc_band(i,bands_num,mod_bw,mod_order,1) :
an.amp_follower_ar(att,rel) : _,modulator :
voc_band(i,bands_num,car_bw,car_order)) :>
_*(1/(bands_num*(mod_order+1)*(car_order+1)));
process =
_,_,_,_:par(i,2,(voc(n,0.01,1,mod_bw,mod_order,car_bw,car_order))):>_,_;
as you'll see from the block diagram the input 2 and 3 cables don't cross over.
but i want them to cross over
is this possible? thank you,
a cheney_______________________________________________
