NEW: Improved audio analysis and volume leveling (R128)

Tell the people at TT to rename their misleading and incorrect terminology. Peak to loudness ratio is NOT dynamic range. And the TT meter is NOT a dynamic range meter.

If that specific column value is painfully high (7,6,5,4) then regardless of what kind of sound quality the source has - it's totally irrelevant to me. Any source with a DR higher than maybe 9 (using TT-DR) gives me a headache after 2 tracks so it's immediately dismissed.
These DR numbers driven by TT have never failed me yet. I have yet to encountered ANY source file with a deafening DR (8,7,6,5) that either sounds good or is worth putting in the library and I have never heard a source file with a nice DR (14,13,12,11) that sounds bad or causes me to stop playback and reach for an Advil.
The R128 stuff is a technical dream to have in this class of program - but unless you know what all those columns mean in a professional sense - I think the TT-DR numbers are a nice easy way for Average Joe to instantly know if he's in the right ballpark and the source is not crushed to death.

My recommendation is that Matt truly stick to the ITU specs. ITU is an international standards organization. "DR" is not an internationally-recognized term. I recommend the term "PLR" or "Crest Factor" to apply to the distance between the average loudness and the highest measured peak of the material. It's not in the ITU book, but at least it won't confuse readers and users as DR clearly does.
The so-called "DR" meter is NOT a measure of dynamic range. Not in the least.

Bob,
100% agree with you.
However - since you are the "man" in some circles regarding this wide topic (I still read your "Mastering Audio" book with purpose :) - it would probably have more weight if you told the TT people to correct it. :)
Just sayin...

I'd definitely like to see this change; I was never very keen on the "Dynamic Range (DR)" naming.
Is there a standard for this Peak to Loudness Ratio? I'm wondering if the Dynamic Range (DR) field should be renamed, or if it would be a new addition.

There is no official standard yet for the "PLR". But it is becoming a de facto standard being pushed by Thomas Lund of TC Electronic. It is the simple difference between the ITU highest true peak and the average loudness so it is not a big stretch to call it by a name. I intend to publicize it and recommend that "PLR" be used as the designation in the next edition of my book, "Mastering Audio." Maybe it will catch on.
