[PD] measuring time with sample accuracy

[Marius Schebella]

there is always the possibility to use a subpatch with [blocksize~ 1]. 
but I did not use this often, because, it is cpu intensive... better to 
find a solution in the signal-domain.
like with >~ from zexy in combination(*~) with a phasor~ or line~ you 
would get a signal vector, where you have only values on the bins, where 
the threshold is crossed.
