Attack and decay are unitless per-sample multipliers, so 1.0e-2 gives you a time "on the order of" 100 samples. It's really an exponential attack and decay, but that gives you an idea. So, your observation is correct - a smaller value gives you a longer attack/decay.

Hello,

I'm trying to work with the module AGC2 but I have some trouble using it.

First problem is : what is the unit of the parameters attack and decay ?
I thought initially that it was in second but after some test it is
clearly not in that unit. Indeed, if I increase the value of the decay
for example, the time of the increase of the gain at the end of a signal
will go down where it should go up.

Second problem (maybe in relation with the first) : the attack value
have absolutly no influence.... From 10-6 to 10-2, I can't see any
changes on the output signal.

Does someone have any explanation ?

Best regards,

Fabien, F4CTZ.
