This is actually useful as it also shows perceived levels, not unweighted RMS................................... Plus VU and PPM.

Yup! There's also the TC loudness meter with the radar history and the concentric circles with the average loudness history. VERY useful!

And while I discourage an emphasis on visual aids, at least they try to read perceived loudness..........

Unlike RMS that we hear a lot about. Why is that?

Because RMS is available, and because it's an accurate energy measure when measuring pink noise it's a better substitute for a VU meter than a peak meter. Otherwise RMS is useless!!!!!!

If you haven't heard, the K-system is expandable to other loudness measures, including the latest IEC measure. It will happen, when someone wishes to bother coding it. Over 15 manufacturers so far have embraced the K-System, all they have to do is convert over to the IEC loudness standard and retain the scale.

I firmly believe that having a "ZERO reference" for the loudness is far more ergonomic for engineers, including relevant change of colors when you are "under" or "over". Far more useful than a negative number (or a positive number) for that matter. The TC meter has a variable scale option and the relative scale permits use of a "ZERO" reference point (like the K-system). This makes a lot more sense than the current Orban scale with "zero at the top" or any loudness scale measured in "phons" or "absolute loudness in dB scale".

Interestingly, there is research on the Pinguin site that suggests that RMS is actually a very useful measure of perceived level:

Go figure...
