stereoread
stereo delay read, non-interpolated. Use with "stereowrite" module and reference to the name of that instance.
Inlets
frac32 delay time (fraction of total delayline size)
frac32 diff
Outlets
frac32buffer wave
frac32buffer out2
Parameters
frac32.u.map time
frac32.s.map diff
Attributes
objref delayname
Declaration

Control Rate

int32_t t2 = __SSAT(param_diff + inlet_diff, 28) << 3;
int32_t t3 = __USAT(t1 - ___SMMUL(t1 << 2, t2), 27);
int32_t t4 = __USAT(t1 + ___SMMUL(t1 << 2, t2), 27);
uint32_t delay1 =

uint32_t delay2 =
