filter range
combination of lp1 and hp1.'basefreq' sets the base frequency,'width' sets the frequency range
Inlets
frac32 cutoff frequency
frac32 width
frac32buffer input
Outlets
frac32buffer output
Parameters
frac32.u.map basefreq
frac32.u.map width
Declaration
int32_t val;
int32_t val2;
Init
val = 0;
val2 = 0;
Control Rate
int32_t f;
MTOF(param_basefreq + inlet_basefreq, f);
int32_t f2;
MTOF(__SSAT(param_width + inlet_width + param_basefreq + inlet_basefreq, 28),
f2);
Audio Rate
val = ___SMMLA((inlet_in - val) << 1, f, val);
int32_t out = inlet_in - val;
val2 = ___SMMLA((out - val2) << 1, f2, val2);
outlet_out = val2;
