Ah, sorry for my completely irrelevant pointer. Now I understand
(after consulting wikipedia again) that you want to compress according
to frequency- and sound pressure dependent equal-loudness contours so
you can comply with standards about perceived loudness? Seems that
this requires multiband
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
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:

Has anyone played around with LKFS or LUFS-based
"Loudness Compression"?
This would be a really handy thing to have
for anyone who creates audio for broadcast TV or Radio,
or movie scores, etc.
When people grab a compressor, this is what
we mostly want. However, in my experience,
most
