You still have to roll your internal delay lines, its just that you know
they will only have zeros going into them.
it should be silent if( zeros_pumped_in > delay_samples*n )
with n = min{ n | feedback^n < threshold } -> n = ceil(log_{feedback}
threshold)

Branching
to fill your delay line with explit 0.0's intead of reading them
from a buffer of zeros doesn't help. We allready know that reverbs cant
support it at all. Efficieny reasons would also rule out flangers, delays,
most filters and choruses.
Maybe I'm missing something, but how can a test that amounts to this NOT be
faster than doing any work at all?
if (me->silent && XAP_BUF_SILENT(me->in[0]) &&
XAP_BUF_SILENT(me->in[1])) {
return;
}
