Auto Gain

Postby mcfadden555 on Sat Feb 06, 2010 2:42 pm

hey guys,

I need a normal Auto Makeup Gain for my Compressor......
But i haven't find something this like that in the forum...
(only find something with RMS auto Gain => But i don't need RMS makeup)

anyone know where I can find a normal makeup gain module for a comp ????

Thanks... and sorry for my bad english :)

I always thought gain makeup was the tranfer curve for the compression.
But if you want it to normalise, you can try to detect the peak level and divide
that by your signal.

Example: t=threshold, r=ratio

t = -24dB
r = 2:1
t / r = -12dB

This is not that easy cause this all depends on the envelope and other things.
It's never to late to be late.....

If my posts misses characters like t, h, u or others its only because my CRAPPY MICROSOFT KEYBOARD needs a hammer to type those keys. This is a new Microsoft Sidewinder X6! :(

Is what your asking for to restore the signal to a comparable level to the pre-comp signal?

If so you'll have to make the control signal's response time an order of magnitude greater than the one used to compress the signal or you'll just uncompress it.

(...of course you'd likely do the envelope follower/ratio calc in code as you could do some serious hop() steps to cut CPU usage)

I remember someone offered a maximiser osm in which, I studied the threshold and attack settings and created my own auto gain vst using the stock compressor. :D

Cheers!
