Hi,
Would it be possible to create a Loudness distribution analyzer in the frequency domain? The one that presents a signal loudness distribution along a freq-cy axis. It would be a great tool for tuning multiband compressors.
Thanks,
Vitaly.
Dynamics Analyzer?

Hi Vitaly - perceived loudness is actually dependent on the whole spectrum, so it would not make much sense to do it per frequency bin. So it seems you are mainly looking for an analyzer that displays the average intensity of frequency bins (since the "loudness" is related to the average energy rather than the peaks). Have you tried for example one of our spectrum analyzers using longer attack and release times?

Oh no, it's not about measuring the Loudness as such. I took this term (Loudness Distribution) from Wavelab as a graph description. Now I see that it was misleading. It's what you call a histogram in your plug-ins.
The idea is to see which parts of a spectrum have a big "swing" (from low to high levels) and which don't. According to this info, we could easily figure out the distribution of bands in a multiband compressor. Else, we could get an idea about bands threshold parameters.
Let's face it, currently we have no clue how to set up a multiband compressor. We use it rather as a tone controling tool (like eq), splitting a spectrum into regions (bottom end, low mid, high mid etc). But we have neither idea about a signal's dynamics before applying it, nor after that. I believe having a histogram in the freq. domain could help us a lot. From a user's perspective it's a very simple tool to use. Just two parameters and two modes. If you're interested I could share my vision of it.
Best,
Vitaly.
