Stephane,
I am shy to disturb https://github.com/grame-cncm/faustlibraries with
such a trivial/random change(s), but I'd like to "finish" the recent
discussion on discord. Note that even ba.time is obviously suboptimal.
I can make a PR if you think this makes any sense.
- ba.time: eliminate -(1)
before:
iRec0[0] = iRec0[1] + 1;
output0[i0] = FAUSTFLOAT(iRec0[0] + -1);
iRec0[1] = iRec0[0];
after:
iRec0[0] = iRec0[1] + 1;
output0[i0] = FAUSTFLOAT(iRec0[1]);
iRec0[1] = iRec0[0];
- ba.period: eliminate the delay line created by 1'
with p == 10
before:
iVec0[0] = 1;
iRec0[0] = (iVec0[1] + iRec0[1]) % 10;
output0[i0] = FAUSTFLOAT(iRec0[0]);
iVec0[1] = iVec0[0];
iRec0[1] = iRec0[0];
after:
iRec0[0] = (iRec0[1] + 1) % 10;
output0[i0] = FAUSTFLOAT(iRec0[1]);
iRec0[1] = iRec0[0];
this change is not 100% compatible when p modulates,
but I don't think this can break something.
- ba.pulse: simplify the condition, obvious.
