NEW: Improved audio analysis and volume leveling (R128)
realysm42:
Guys,
Thanks for rthe feature.
Does enabling just levelling hurt dynamics and sq?
If yes, is there anything that can be done about it?
If I disable I internal volume, so its always @100%, does this feature still work? I ask because I'm getting an analogue preamp installed and would like to us purely that.
Thanks for your help.

As long as your audio device is at least 24-bit, it should not hurt sound quality.
If anything, using volume leveling should improve your perception of dynamics.

Yes, Volume Leveling will still work.
MikeO:
I previously asked on a different thread if volume levelling will affect quality. I should have done the test , being lazy !
I did the test , I used 2 of my "test tracks" , Joni Mitchell - Blue - A Case of You , and Dire Straits - Love Over Gold - Private Investigation both FLAC via MC from remastered CD's
Out via ASIO to a Cambridge Audio DAC Magic , then Denon AV amp (set Direct) and HD800 .
Even to my aging ears , I believe I can tell a difference on the tops , sibilance as less pronounced and the aggressive "twang" of the guitar in Dire Straits was definitely missing.
I saw a dramatic reduction in volume of some tracks , presumably because I have a very high level track or two in the library
Are there settings to adjust ?. I have switched it off for now

Volume leveling works by (mostly) reducing the volume of tracks to recenter them to a specific standard level. The result is that (with leveling on) most music will sound about the same volume regardless of compression (i.e. heavily compressed music will not "sound louder" due to compression). Generally speaking, louder music (even slightly louder music) sounds "better" to most people, which is how the loudness wars got started to begin with.
You don't mention whether you readjusted the volume in your experiment so that you were listening at the same "effective" volume level in both cases, but, if you haven't, I would recommend doing that before coming to any firm conclusions about volume leveling.

If you add an expression column with the following code, are there any values above 0?
--- Code: (True Peak Level) ---math(removecharacters(listitem([Peak Level (R128)],0),+/ dBTP,0)+1)
--- End code ---
If they are above 0, than means what you're probably hearing is the removal of inter-sample clipping, which is a very bad artifact of modern mastering processes.
If not, you're just hearing a difference in volume.

Everything is normalized to -23 dB, so it depends how loud the track was mastered.
