yes, Acourate uses similar thoughts.
See attached picture (if it is not accessible please tell me, then I will copy it to the Files section).
The curve used by Acourate (green) is a result of interpreting the time domain signal properly, not just a manipulation of frequency domain data. Thus the results of DRC and Acourate are sligthly different. But at the end we are hunting for the best curves. BTW both DRC and Acourate curves are again different to the usual 1/n-octave curves.
PS: please allow me to talk about AcourateNAS, a recent solution to convolve a music library offline before playback. The original files can be kept as backup. The convolved files can be played by any state-of-the-art streaming solution. No additional online convolver hardware required. AcourateNAS also allows to normalize tracks according to the true peaks (according to ITU1770). This ensures that no intersample clipping will occur.

is largely the "upper envelope"--that is the
curve that goes through the peaks or maybe say 2/3s of the way
up the peaks. This is because the ear is more sensitive
to peaks than dips.
You can find some thoughts on this on Denis Sbragions site
I believe that UB is incorporating similar thoughts
(or has already) in Acourate.
This is in a sense standard psychoacoustics, but
it is surprising how often it is ignored in
room crrection and in speaker evaluation,too.
