Microdynamics measure of track (in addition to macrodynamics measure as of today)
"Dynamic Range (R128)" measures the macrodynmacis range according to standard AES/EBU, fine.
Microdynamics (liveliness) of a recording cannot be measured in JRiver today (nor in any other program).
"DR (Dynamic Range)" is also not suitable as many people noted.
Here a proposal how to calculate, very close to standard AES/EBU (not inventing the wheel again...):
1) Take the "Dynamic Range (R128)" algorithm (already built in JRiver) and make the RMS-window size instead of 3seconds, variable. It should be possible to put values from 25ms to 3seconds (3 seconds is today). Value in the settings.
2) The Window-size would then be a parameter: 25ms-3seconds
3) The parameter may be named: "Dynamic Range (R128-50ms) for a window of 50ms, a tag field to choose from.
I am not sure if other internal parameters must be adjusted to account for the changed RMS-window size.
Benefit:
Would have a measure to judge if compression (overcompression) was done or not. If liveliness is in the track.
Why this should work:
