smVCA
"voltage controlled amplifier", multiplies v and a inputs, with lowpass filter smoothing from k- to s-rate. This makes envelopes a bit more dampened then with linear interpolation.
Inlets
frac32buffer audio input
frac32 gain input
Outlets
frac32buffer output
Declaration
int32_t prev;
int32_t step;
Audio Rate
step = step + ((inlet_v - step) >> 7);
outlet_o = ___SMMUL(inlet_a << 3, step << 2);
