anyone knows if there is a way normalise to xxLFUS and Truepeack at the same time.

I am about to try the two diferent scripts by no-fish for LFUS and TP but i guess if i normalise first the LFUS and then the TP values for LFUS (or the other way around) values of the precedent normalization will be changed? no?

So i guess, i am looking for normalization of both LUFS and TP at the same time if this exist (like nugen LM correct plug)


thanks in advance

I don't see how you could do both without altering the dynamics.

I could see have a LUFS normalize script with a MAX TRUE PEAK reading with some kind of limiter appleid to prevent true peaks over a certain value.

But if you wanted to make the LUFS be -14 and the true peak exactly -3dB for example, there is no way to have both without some kind of dynamics processing involved.

I guess for my scripts I don't care about the true peak because I run this at the start of my mastering sessions to get all the songs on the same page before I start mastering.

I would personally just use the existing script and then get the Tokyo Dawn Records Limiter 6 GE plugin to control the true-peak levels.

MRMJP is right, you can't normalize to both. One is a momentary peak measurement and the other is an integrated/program averaged measurement. Probably the best you could do would be to normalise first to LUFS then run some analysis to tell you if and where the audio is exceeding -3 dBTP. Then either a limiter or a manual mix change can fix those spots. I think some meters have automatic logging like that and perhaps some scripts drop markers and such. I should know but since I'm usually mixing for -23 or -24 it is exceedingly rare I even get close to the dBTP limit and usually obvious where the high point is.

ok i understrand thanks guys, i am asking that as i am doing mixing to netflix specs which are -23 and -3tp.

is there a jsfx limiter that can do true peak limiting?

thanks

The last time I checked the specs, Netflix is -24LKFS which is identical to -24 LUFS(I checked with lots of approved mixes).

-2dbTP . In other words it’s 1db below EBU R128.

If you want to be sure, get the most recent Spec. The requirement hasn’t changed from the last time I checked, and my mixes are passing QC.

Sidenote, I use Voxengo Elephant, which can do 4x oversampled limiting.

I think one of the least expensive Truepeak limiters may be Barricade by Toneboosters, with its ISP mode. Don’t know if it does channel-coupled 6-channel limiting though.

(3) check the results

And here are the 'before' and 'after' waveforms and loudness levels in MMultiAnalyzer.

Check the orange line in particular - running very close to 0 LU.
This is cool. I might assign this as my external wave editor & see if I can use it to normalize from within Reaper...

I use it and V4 does. It actually does up to 16-channels to cover 3rd order ambisonics and the strict channel based atmos as well.

I believe LKFS and is the same as LUFS except that it implies you calibrated your room using the K system

It's been a few years since I read this. The K-system comes from Bob Katz iirc. It had nothing to do with loudness measurement from what I could find. Bob actually recommended changing to loudness measurement at some point.


LKFS was based on the first ITU 1770 spec, which describes the loudness measurement method. The EBU R128 recommendation built itself around that measurement standard and added the gate functionality, which is now part of the ITU spec (1770-3 iirc and we're at 1770-4 now).


Btw, Nofish did some scripts to measure short term max and other stuff. That ought to be neat to add to the SWS Loudness functionality, if it isn't already in there somewhere. That kind of stuff is probably neat for normalizing a whole bunch of shorter items.

One more thing. Netflix specifically bases the LKFS measurement on the 1770-3 spec, which makes it identical to LUFS. At least that's my educated guess backed up by lots of measurements.

If I remember correctly Bob Katz idea with K-system was also that you work with a constant listening volume/loudness. So you need to calibrate it to your speakers...

The K in LKFS is referring to the K-weighting applied to the meter reading. It easy to see why it would be confused with the Bob Katz K system, especially since both push for similar workflows using calibrated monitor levels and averaged loudness measurements.

Oh ok, I'm not sure where I read that.

Yes the k system is a way to calibrate your monitors to a standard volume, so you know it will play at the same level on anyone else's system who are also using your chosen k value

I use the nofish max momentary script a lot. Its the best way I've found to get large amounts of assets to a similar volume. Though it is still essentially a hack really.

We really need someone to make some sort of machine learning ai which can make all your sfx the same volume, as a human would perceive them, no matter how long they are.

If this was straightforward to do it would probably be the current Loudness measurement standard already.
