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

[TonyGlover]

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.

Where does write this, why you can't measure the LUFS loudness just for high frequencies, for example?

You misunderstood what lufs means, whatever hears the ear can be approximated in lufs.

If you say that it does not make sense it is deduced that you do not hear and you cannot separate the bands, it has no sense for you.

Loudness of single frequency bands??

So in your opinion, a frequency band contains only one, for me it contains a lot ...

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.

LUFS can be measured on bands, why not!?

but be less accurate

is the most accurate, read more, learn more and talk a little.

The program is useful to compare the loudness adapted to the human ear on three frequency bands or more === excellent idea.

I don't know why I waste my time with such stupid statements.

New things require an open mind... that's the problem.

I got it by clicking on the FREE DOWNLOAD button, now it wants a serial number.

Why you don't test your affirmation? Put an EQ and let only the bass then see if you can measure Lufs on the output.

Here I notice a repeating confusion: the filters that the Lufs algorithm uses are specifically designed to adapt the measurable loudness to what the human ear perceives. Obviously, this doesn't mean it can't be measured on bands. Lufs is much closer to the human ear than peaks or RMS, which is why we chose Lufs in the program. The important thing is for the track to be balanced across the bands in accordance with the human ear.

Correct. If you split everything into bands you get something else that might be related to LUFS - but it's not LUFS anymore.

Wrong!
Just a statement that is not based on anything, where does it say in the Lufs presentation that? And how many frequencies do you think Lufs needs to be?
Nonsense

I suppose this confusion comes from the "integrated" term, but does not refer to frequencies and has to do with time.
This confusion can only be make by beginners.

It's weird that you three almost never post, but somehow show up in the same threads
