you mean like the absolute value? like [abs]?

hmm, a single sample is not really representative for the signal, is it?
imagine you have a signal:
0 0.33 0.66 1 0 0.33 0.66 1 .....
which will have "0" each and every sample that is dividable by 4 without
a remainder; since you bang the [snapshot~] only at block-boundaries,
your vu will always display 0 (-inf)
if the signal is offset by -1 sample, your vu will always display 1
(unity gain; full-scale)
so i don't fully understand your why you don't want to use [env~]?
