Hi,

"Audio Analysis" is a great feature in JRiver MC, but I think the results are a bit misleading. Can anyone explain why a "volume level (R128)" of -6 dB is obviously louder than one of +6 dB? I guess what JRiver means here isn't the volume level but the gain correction value to reach the target loudness of R128 (i.e. -23 LUFS). Am I right? Then please don't call it "volume level" anymore. Or, if you prefer to stick with the name "volume level", then just reverse the plus and minus signs. In that case a "volume level (R128)" of for instance + 6 dB would be 6 dB too loud and would have to be reduced by 6 dB to reach the R128 target. So "volume level (R128)" would indicate the level relative to -23 LUFS.

The track is 6dB below the target, therefore its volume level is -6 LU because it is too quiet.
 
An expression column or custom field will do what you want:

Code: [Select]

FormatNumber(Math([Volume Level (R128),0]-2*[Volume Level (R128),0]), 1,,/ LU,)

A simple search before posting your first post based on assumptions and requesting a change to the software might have been a good idea.

What you are hearing as a louder track (the -6 dB track) is probably a larger Dynamic Range. The +6dB track is probably a victim of the Loudness War and has a compressed Dynamic Range, which means lower peaks and so it sounds quieter.

Do you have Volume Leveling turned on in MC's DSP? Because if you do, MC would adjust the volume during playback as per the R128 tags, and they should be played at the same volume. But the -6dB track with the larger Dynamic Range could sound louder to your ears.

No volume levelling turned on. I did a comparison with the R128 loudness meter plug-in from audiocation: It indicates nearly the same (integrated) LU values as JRiver MC but with the plus/minus signs reversed. So the track with the louder perception shows the "+" value.

BTW: I didn't manage to get the audiocation plug-in (32 bit) to work in JRiver MC (32 bit), but it did work in Foobar instead.

I realize this is a very old thread about Volume Leveling, but the answers it contains appear to be wrong, so I am posting anyway.

As confirmed in the following thread:
https://yabb.jriver.com/interact/index.php?topic=103933.0
this is the formula for calculating the Volume Level (R128):

    [Volume Level (R128)] = -23 - {R128 Average Loudness}

Example: if a track is 6 dB louder than the R128 target of -23, it has an R128 Average Loudness of -17. Therefore

     [Volume Level (R128)] = -23 - (-17) = -23 + 17 = -6.

Hence the volume level of a track that is too loud is negative. Hence the OP was right that a track with VL -6 sounds louder than one with a VL of 6, and the answers that followed are confusing or simply wrong.

This is also confirmed by the fact that peak levels of tracks with negative VL are always higher than peak levels of tracks with negative VL.

Unless I have misundersood something of course, so please correct me if I am wrong.
