I know there arent any hard and fast rules but sometimes I wonder if there aint some accepted practices. I was going through a mastering with waves tutorial.

A kick drum had been eq'd and compressed and the makeup gain was set to get level before compression. Is this a general practise?

thanks

Yes. And no. You just use it to set it to whatever level it needs. Might be to make up for the GR, might be more, might be less.

If an "A/B" situation is in order, then make-up = to GR is a nice way to get an idea of the difference in the sound...

Gain makeup is just a fancy word for gain. That's all it is. Having a gain control within the compressor is often just a convenience. You can "make up" the gain within the compressor or after the compressor or NEVER, depending on the gain structure of the chain or system you are working in. In my system, the analog compressor precedes an A/D converter since 9 times out of 10 I'm playing back a digital source. Unless I'm purposely trying to clip the A/D converter, I don't care if the signal from the compressor hits the A/D at -1 dBFS peak or somewhat lower. I'll make it up later in the digital chain without audibly affecting the signal to noise ratio.

So, the main usefulness of the gain makeup control? It's to help you evaluate the sound quality of the compressor when you hit its bypasss button. If you adjust the gain makeup control for the same subjective loudness when in bypass you can (fairly objectively) evaluate the effect of the compressor.

This is something I'm doing alot. But I've been wondering lately if I should adjust for peak level, rms level or just for what's sounds the same?

Sorry crabtwins, I hope I didn't hijack your thread but I had to ask...

You're not hijacking, Cojo, but you're not listening :-). The whole purpose of the gain makeup knob is for the listening. You could sit there all day long and adjust the gain makeup by any meter, but learn nothing at all. Because neither RMS nor peak will tell you what "sounds the same." There are too many variables and the ear is the judge.

The initial setting for the gain makeup should be unity gain when the compressor is not compressing. That you can (and should) adjust with a meter and a test tone. But notice that the output goes down as soon as the compressor kicks in. Should you then "make up"? Not required, unless you want to compare with the ear.

I'm listening now! heh

I've probably done it the way you said I would all the time, just not knowing about it. Thanks for taking the time with us!
