Rms compressor plugin?

[Charlie-O]

Is ther a such plug in that compresses the rms level?

I think the Sonic Timeworks CompressorX can do it...not sure not infront of the studio computer at this moment...you can check it at

Actually I would say most modern compressors of reasonable quality today uses RMS rather than peak detection. So there are many RMS compressors available to chose from. But the implementation of the RMS detection and how it averages etc will differ from compressor to compressor. Peak detection is mostly used for limiting/peak taming purposes.

Our compressor Compadre beatpuncher (VST/PC) uses RMS detection.

Elemental Audio Neodynium can be switched between peak & RMS detection, but it's not a very intuitive compressor to use, for me anyway.

Logic compressor.

Does it? How do you select which?
If you are refering to the "Low Ref" / "Peak Ref" switch, it only affect how make-up gain works and not what detection is used.

Waves Renaissance comp. And RennVoxx. And Rvox. etc. all the renn comps.

thats weird, i have to admit i havent read the manual so i guess i could have been wrong all along.... so..... why the differentiation on peak or low for make- up gain?

From the manual:

This has no effect on the sound but affects the output level and how the makeup control works:

LowRef mode [Low-level reference].
This is the conventional mode for compressors, in which the output drops as
the threshold is lowered (and more gain reduction occurs).

PeakRef mode [Peak-level reference].
This permits easy adjustment of the Comp/Exp when you want to keep peak
levels approximately the same. For example, when in PeakRef mode, as you lower the Comp/Exp threshold, the
output gain increases, keeping the output level approximately the same.

As mentioned earlier, I would assume that most modern compressors of decent quality uses RMS detection...unless otherwise stated or unless it gives you the option to choose between RMS or peak.

Cheers,

NO! It is an artistic/technical distinction. You use what is appropriate for the sound you want. Like an LA-2 (RMS) for vocal, 1176 (Peak) for bass, and so on. There are very good reasons for choosing which for what!

It is not the quality of the comp, it is the type you chjoose for a certain sound...

I'm not argueing that there is no usage for compressors based on peak detection. You are certainly right that there can be (and of course there's also limiting). But then again, there can be such a big difference in exactly how the "averaging" aspect (and other aspects) of RMS detection is implemented, so the RMS envelope used in one compressor might be very different from what's being used in another. And thus making the kind of distiction you are making ( RMS for vocal & Peak for bass) a little too general.

But what I was in fact argueing was, that while the original poster seems to assume that peak detection is the standard used in most compressors today, I would think that it's more common that they are RMS based..unless otherwise stated.

... and I was saying that there are both types, and it is immaterial which is "standard" or "common" - there are different types for different uses. It is misleading to say most or all are one or the other.

My generalition was just to make the above point, not about how to use a compressor. It is always an artistic and technical decision. You can even have some of each with software comps!
