Your math seems right, but your assumptions/implications about stereo audio signals are not. As @Cella mentioned, the left and right channels of a stereo signal may be completely correlated, completely un-correlated, or anywhere in between. L+R = 2 * L is only true in the (rare) case that the channels are completely correlated (actually identical).
Likewise, your analysis glosses over this distinction.
This issue is exactly why “good” mixers have a choice of perhaps three different “pan laws”.
I’ve never met a CPU pig I couldn’t easily make more efficient. This stuff here is pretty basic. You are probably familiar with all of this, and more. But I’ll bet one of more of the simple techniques here will do it.
Glad to see this module, btw! thanks.
Nice. I have to say, though, that both versions use an enormous font that is pretty much out of scale with other VCV modules. Why not shrink everything by using a scale that’s more like other modules that someone might be using along with these excellent now modules?
You could even use tool tips to explain what they units are. Not that that’s great design, but these modules are awfully big.
First of all, apologies, seems like I highjacked discussion here with this new module. Maybe it’s time to open Cella development thread 
@Squinky, I’ll definitely revisit your notes!
oh, I don’t think you “hijacked” that thread. Of course some people get more upset about that than others. Anyway, glad to see a real loudness meter in VCV.
This is valuable feedback!
My thought process was: this is monitoring module, so values should be legible at lower zoom levels, for example during performance or recording. Packed readings with small font will require zooming into / going to meter to check in.
But if it’s something users want, I’m totally open to try 6HP «micro» version. Will report shortly.
Very true.
The whole ratio of 2 and 3 dB thing was based on that L+R = 2 * L assumption nonetheless, since, as you and Cella noted, it is only valid under that assumption for a Stereo signal.
I guess most people would actually even call L+R = 2 x L Mono and would expect at least some differences between L and R before calling it Stereo.
Anyway, I could have been clearer about my assumptions instead of just starting with…
The whole thing actually mostly explains how 3 dB equates to a power ratio of 2, as in the concluding sentences. It just so happens that summing two of the same Mono signals also results in a power ratio of 2 and 3 dB for the resulting ‘Stereo’ signal.
@Squinky @contemporaryinsanity How about this version? Unit is displayed on hover.
I like it!
Cool, I also came to believe it’s more functional, haha.
Release was updated. I decided to keep Loudness Meter and Loud.
Modules have been published to the library: Loudness Meter and Loud. Thanks you @kwurqx for the idea and everyone for testing and suggestions.
