Re: AGC to keep audio energy to some target level

Postby KG_is_back » Mon May 04, 2015 3:13 pm

I believe what you mean is something like a RMS limiter. RMS means it takes an quadratic average of certain region:
Code: Select all
RMS=(x[1]^2 + x[2]^2 ... x[n]^2)/n

Which coresponds to average energy of a waveform. Then an limiter is applied, where this RMS is used as a sidechain.

Here is a very basic soft knee RMS limiter. Poke inside to get an idea of the main ingredients. Hope that helps!

Thk, Martin,..this guy is a real guru of audio.

Question:

Why RMS, instead true peak?
For ACG no wll be better true peak........right? wrong? :shock:

I test this a lot nd work very well.
But there is some way to improve and make sound less pump effect?

Also is possible to setup the ACG to desired lelvel output, by example -15db and the out be leveled to around that level with not noticiable pump effect?

I testa lot and cant find the way to target the output to desired value in accurate way, and also how remove non desired sound artifacts.

Well I said it was very basic, didn't I? :mrgreen: You can play with attack and release to try to reduce the pumping. If that doesn't help then you might experiment with look-ahead capability. And yes, of course you can use peak instead of RMS, however the OP asked specifically for RMS. If you don't like the soft knee, replace it by a hard knee. Lots of possibilities. ;)

There is a commercial plugin called 'Hornet' that does a specific job [very handy] ...

It monitors an audio track, and based on the User setting [i.e.: -18dB RMS], will adjust the GAIN of the track to HOLD at -18dB.

It does NOT use any type of Limiter or Compression ... only adjust overall gain.

Not to re-invent the wheel ... but it would still be cool to have a FS version :mrgreen:
