[PD] aenv~

[Conor]

Hi folks,
another beginner question...
I was hoping to use a an adaptable envelope on an audio signal. I copied 
over the external aenv~ into my extra folder. When i start a new patch 
and make a new aenv~ object, it seems to initialize the object properly 
providing 5 inlets and 1 outlet. I couldn't find any examples so via 
trial by error (and peaking into the src :-) , far as i could make out, 
the first inlet is for a bang or 1 to trigger the envelope, the second 
to fifth are the values for a typical ADSR envelope. In my understanding 
of such an envelope the attack,decay and release times  are measured in 
miliseconds while sustain is a scaling factor (0-1 - floating point). I 
then scale the audio output of what is coming out of aenv~. Firstly is 
my understanding of this correct? Secondly are the values based on the 
unit circle (0-1) or what scale should I consider.

Best regards,
Conor
