Thanks Katja.

I did not intend to imply a particular compression method.

I was only asking if anyone has created
a compressor in Pd with the goal of limiting based
on Average Loudness rather than Peak Gain.

I don't really know how it works,
except to guess it is related to
Fletcher–Munson curves
.

I want to get into broadcast more.
A LKFS or LUFS external (meter and compressor)
would be very useful.

Limiting based on Loudness is becoming
both a US and EUR broadcast standard,
yet there aren't many tools out there,
it seems.

Frankly I had to ask Wikipedia what LKFS and LUFS is. They are
loudness standards, they don't indicate compression method.

Here's a peculiar method which uses detection of instantaneous
amplitudes instead of peak sample values:

wouldn't use it for all purposes. But it reacts super fast to
transients. I use it on acoustic input in live performance.
