i think it can be made as an abstraction.

as Loic explain me, the algorythm is quite simple : 
a maximum is find, but send only when the curent input is less than 90% of this maximum.
it's a good way to find a maximum of a noisy input.

i think the best would be to rewrite it in pd, but since i don't have time, it's ok for me to include external in the mapping lib.
moreover, i'll also have some external to add there, once i'll find the time to write them...
