Hi Joao,
This is just a guess, but you might be getting amplitude information
from different parts of the sample. When I'm trying to measure the dynamic
of a real-time input, I usually look at the maximum of all the values fiddle~
outputs. If the sound is percussive, it's sometimes OK to wait 1/10 second
after the attack (identified either by fiddle~ or bonk~) and just 'gate'
the amplitude at that instant...
cheers
Miller
