envelope follower

May 3, 2006 | 5:40 pm

Hi, I’ looking for an envelope follower for max. The only one I’ve
found is the vectral~ but this one is a vector envelope follower, i
need an amplitude follower like threshold~ in pd.
Thank’s everybody.

#P comment 15 116 169 9109513 The Envelope follower takes audio input and filters it to get a general shape of the amplitude envelope. Then , this amplitude can be applied as a modulator to other audio sources.;

Hello

I did one with the bargraf~ object
who gives you the image of amplitude but also the
DB and linear values
dowloadable at gmem.org
it works fine

best
