Default Realimit. How does it work?

What are the features of Realimit and how do you use it please? Thanks.

ReaLimit transfers the threshold to the ceiling, in other words sound that comes in at the threshold goes out at the ceiling. No signal is allowed to be output above the ceiling, so any input above the threshold is compressed. The usual result is that the output is louder.

For example if the threshold is -6 dB and the ceiling is +0 dB, the overall signal is boosted by +6 dB, to transfer the threshold to the ceiling. Input signal above -6 dB, which results in output signal above +0 dB, is compressed so that it peaks at exactly +0 dB.

Okay. Thanks for the great information. I'm definitely going to try it out. I have been using the airwindows NC-17 with great success and am excited to compare the two. Thank you for the info Schwa

so this is meant to be pretty simple, no different kinds of release, kinda no frills? I really like it, even though I'll be sticking to ozone for now

Jae, would you consider changing your signature to something happier? How about.... "Reaper is like a warm furry blanket".

The best thing is the visual interface - Voxengo put a realtime peak display on some plugins but it's in a submenu and not zoomable, like ReaLimit. I bought ClipShifter for a similar function but again, its UI is migrainacious and it's hoggy.

ReaLimit is ideal for working with pre-mixed/bounced stems, one (edit) instance on each track.

I just checked Realimit and I already like it. That along with the "Loudness Meter Piak/RMS/LUFS" will be on my Master FX track from now on, or until there's a reason not to.

ReaLimit has 10ms of latency that it uses to smooth the gain reduction and minimize distortion. Lowering the latency would come at the cost of some loss of smoothness and increasing distortion. The quality decrease would likely be acceptable down to about 2ms, but it seems like a shame to trade quality for latency.

A limiter with less latency will either introduce distortion on low-frequency material (10ms is about the wavelength of G2), or have a fixed hold time that results in less responsiveness for higher frequency material. The result may still sound good depending on the material, but like I said I hate to trade away any quality.

Thanks Schwa. I only use the x42 peak limiter to shave off the loudest peaks and do not boost the signal with any kind of make up.

Whether or not there's gain boost doesn't really matter. Anyway, we'll think about whether it makes sense to add a low latency vs high quality switch or something.

I would welcome a switch that increased performance over quality. The peaks I shave off with a limiter are generally transients in the mid to upper frequencies. Like when two or three snare drum hits will put the track into the red, but all the rest of the hits are sitting real nice in the mix.

I agree 100%.

10ms is the perfect number to use
as the default setting for this plugin
(best quality). I would not change that.

If the plugin does come with the option (check box)
to use low latency mode, then the user will need to understand and accept
the fact that the low latency setting will effect the sound of the plugin.

+1.

There are dozens of limiting plugins that will give you reduced quality/smoothness, some without asking. If latency is an issue, work on stems. It's what I do when I want to use a particularly hoggy plugin (which ReaLimit isn't).

I'm gonna add a real life application for such a switch.

Live streaming.

When I do live shows on twitch, I just want to be have a security blanket in case I give'er too much on the vocals or guitar, but still be loud enough when I play quieter songs.

Having a low latency limiter will allow me to monitor my mix live instead of sending the output of my limiter to OBS while I'm monitoring on a parallel channel without a limiter.

Bad things can happen (and have happened) when you don't monitor the "real" output while streaming.

If you by that mean "does it have true peak limiting?", the answer is "yes it does". And does a very good job at that too. I've been testing it on different kinds of material and I just can't get it to "leak", meaning that with TP on, the peaks actually do stay at the ceiling

What kind of black magic whitchery is this limiter ?

Sound cleaner than any I have tried. Didn't dig deep into how it handles transient in terms of perceived preservation, but it is clean as whistle !

Great job !

I'm very grateful for this plugin. I don't often use ReaPlugs, but I've been looking for a simple true peak limiter for awhile.

Many third-party limiters are closer to mastering suites like Ozone or Limiter No. 6. I got my mixing/mastering template from Tod, which only requires a simple TP limiter at the end of the master chain. It's on from the beginning of the mix to prevent stray overs. A fat, hungry suite like Ozone doesn't work super well for that.

I have been using bx_limiter, but it's not true peak. The XL function is very cool, but it's not so helpful on the 2buss. ReaLimit is perfect for this purpose.

I squashed a mix with 20db reduction, couldn't bring it into distortion at all, it just gives a overcompressed kind of artifacts, really different beast ! Witchery !

How are you setting ReaLimit for mixing, Tod? I've just got it default, except for clicking on true peak.

Thought it was just me, but good to hear it isn't. Realimit handles all my limiting needs since they've implemented it.

ReaLimit is a fantastic tool as it is.
Just use it to get it "under your knees".

I abandoned plugins that before I was using a lot, since ReaLimit. Fantastic simple tool!

I like ReaLimit! It's very soft and undistortable.

I'm i hearing right, that ReaLimit has no clipper after gain reduction stage?

ReaLimit sounds softer than Waves L1 and Thomas Mundt LoudMax (very cool L1 alternative)

I tried bunch of Reaper built in limiters. Even Event Horizon Limiter/Clipper introduce notable distortion at gain reduction 3 and more dB's. But as other Reaper built in's has no latency at all. Compromise?

Yes! Excellent tool.

First: congratulations to Schwa & Team.
Second: since Realimit arrived to my life I use it intensively.
Third: the distortion amounts even at hight ratios is amazing.

Again thanks Schwa!

yeah I find ReaLimit better than all other category alternatives, I noticed it is also a maximizer, that is increasing the threshold reduces the a little the dynamic range, and it is not the same to put a volume adjustment with the same db amount before in the chain, am I right?

Seems to me that latency could be reduced by using Reapers oversampling feature.

No. You can reproduce a 20 Hz signal with a 40 Hz sample rate just as well as 192 KHz, but in both cases that wave is 50ms long.
