Three Band LUFS Analyzer - new feature in the field of loudness meter

[SaschArt]

Greeting!

Our team has launched today a free unique plugin that can measure the LUFS loudness across three distinct frequency bands: low, medium and high.

3LufsMeter
https://vst.saschart.com/3lufsmeter_lou ... three_band

We invite you to download the plugin while it's still free, the next version cannot be published for free, there are investments that we should recover.

However, we offer the plugin for free for all the following versions to those who contribute. This means that you will have to publish preset or tips of use on the plugin presentation page. If we find them useful, we'll grant the author free access to all future versions of the plugin for life.

This is a new functionality in the audio field, and it needs to be thoroughly tested and the most useful ways of using it should be discovered.

This is exactly what I needed. I would put it on four bands with two on middle, is that possible?

[SaschArt]

Yes, you must use two instances of 3LufsMeter
On the first split 200Hz and 800Hz and check first two bands.
On the second split 800Hz and 2000Hz and check next two bands.

If you have caught the idea, it must be an additional frequency of separation common in both instances

You weren't kidding. 5 days later and it's no longer free. €33,-
Curious about the use in mixing to make sure you hit certain ranges in the bands.

I think that you are taking the LUFS measurements in the wrong direction. All this was done for a broadband metering. Of course, you can bring it to the extreme and build 31 band meter, but for what?

LUFS requires the full audio frequency spectrum in order to compute perceived loudness. LUFS doesnt make sense for a band limited input. It could be some other kind of loudness but it wont be LUFS. A multiband LUFS meter doesnt make sense to me. I'd be interested to know the rationale for how this product works and how it's implementation would be useful.

Exactly.

This was the first thing I thought when reading the title: Who the f*ck is using LUFS on individual bands??? What shall this be good for or tell me?? Loudness of single frequency bands??
Sorry, this doesn´t make sense at all!

But I didn´t want to start a war here... now that you made the start I am all in...

I think there are uses for this. Specifically comparing a mix’s bass loudness to a reference track’s for instance.

Wouldn't an RMS spectrum analyzer like SPAN work just as well for that?

You can simply use any eq or multiband and then solo the frequency area that you want to measure.

Sure? I have never really gotten along with SPAN personally, it’s obviously an excellent plugin but I just don’t vibe with it

Do standard EQs show the frequency spectrum in terms of LUFS? I was under the impression they were using a much more simple calculation such as Peak and Hold?

LUFS needs a full spectrum because of the included weighting (Filters). You get wrong numbers by splitting the spectrum into bands and then applying the algorithm to each band. For bands you can still use peak/RMS - or even better, your ears. LUFS is only an approximation anyway and not even a good one.

I think this is correct. My understanding of LUFS is the result is the input signal weighted agaist a full bandwidth model of the frequency response of human hearing. Since the model is full bandwidth, the input needs to be full bandwidth. A band limited input will result in a LUFS that is weighted properly but perhaps not entirely accurate. I may be wrong but I think the LUFS spec recomments full bandwith input for most accuracy and warns band limited inputs will still be relative to the model, but be less accurate. If I remember I will dig up the spec and see what it says on this.

Your eq doesn't, but your daw metering most probably does. It ain't that difficult : Solo a band and read the values on whatever metering you are using.
