NEW: Improved audio analysis and volume leveling (R128)

I think R128 has nothing to do with Dynamic Range. Why did you name it Dynamic Range?

This is what I mean!

The TT Dynamic Range values are a measure of the crest factor of the music. Crest factor is the difference between average and peak levels in a track. This is based just as much on music style as whether there is compression used during mastering.
Actual dynamic range is the difference between the loudest and quietest parts of a track. The R128 values are a measure of the actual dynamic range of a track.
You can see from the Dynamic Range (R128) numbers from your two examples that "The 2nd Law" actually has more difference in dynamics than "Kiss Me Kiss Me Kiss Me." However, "The 2nd Law's" average levels are closer to its peak output which result in a much lower TT DR number.

The R128 Loudness Range is a measure of the difference between loudest and quietest portions of an audio track and should not be confused with TT Dynamic Range Meter which measures crest factor or the use of "dynamic range" to refer to the signal to noise content on a recording. JRiver is using Dynamic Range (R128) here because it probably has more meaning to people than Loudness Range.

Hmm...I guess I was hoping to get a meaningful TT dynamic range like measurement. I don't see where MC19 returns the average R128 level. I'm assuming that would be -23 LU -(Volume Level(R128))? It would seem *in general* that a more negative Volume Level (R128) would indicate a more compressed/clipped file as long as the peak values don't drop as well. "The 2nd Law" averages about -15 LU for the Volume Level (128) with Peak Level (128) +0.5 dB while "Kiss Me Kiss Me Kiss Me" averages about -7LU for the Volume Level (128) and -0.5 dB Peak Level (R128). That would give "Kiss Me Kiss Me Kiss Me" about 7 LU more dynamic range which would correlate with the DR Database? Please correct me if I'm going off the deep end.
I do like the new volume leveling system.
