Way to quantify degree of loudness-war impacts? (not loudness itself)

I am not asking for a utility that computes some average loudness measure (like ReplayGain). (Edit: Argh, thought I was clever to avoid the quotation marks " and ', in order to keep the board from cropping the subject. Forgot about the slash.)


Rather, I am asking whether there have been developed reasonably good measurements -- and utilities implementing such -- for scanning for “loudness war victims”. E.g., criteria like
- dispersion of amplitude (e.g. standard deviation), over some (moving?) average
- distribution of signals near the digital 1.0000 to identify brickwalling (hard or not-very-soft limiting)
- every track on an album boosted to about the same maximum


Of course it will vary over musical genres, but a model that could scan a batch of subjectively “similar” music and with a reasonable accuracy (i.e. sensitivity/specificity) detect those “bad remasters”, would be a good start.


Anything? Anyone?

Would you like to qualify your suggestion so that it doesn’t directly contradict the first sentence in the thread, or should I just send it to the Recycle Bin as evidence of how not to read?

I am not sure what you mean here (... sure you read the 'not'?), so please ask again if I do not answer to your question.

The 'your suggestion', is that those three points I suggested? For example, the first part of my suggestion (the 'dispersion' measure) is kind of suggesting a loudness measure, then it isn't. They are related as standard deviation is related to mean. I am not asking about a measure of average, affirming (not contradicting, directly nor indirectly) the first sentence (which says that I am not asking for a anything like ReplayGain).
