DCA
De clicked "Digital" Controlled Amplifier: multiplies "in" and "gain" inputs. The gain input is NOT INTERPOLATED, DCA is "anti "clicked by updating gain at zero crossings of the input. This allows very sharp attack transients without additional clicks.
Inlets
frac32buffer audio input
frac32 gain input
Outlets
frac32buffer output
Declaration
int32_t gain, _in;
Init
gain = _in = 0;
Audio Rate

gain = inlet_gain;
}
outlet_out = ___SMMUL(_in, gain) << 5;
