I'd like to add one bit of good news. I own two CD releases of Yes's "Relayer", the first one being released somewhere around 10-15 years ago and the second one being a remaster on Rhino IIRC, and there was no change in loudness. In fact, all three tracks have even lower RG values than before!Name Original release New release The Gates of Delirium -7.52 -7.41 Sound Chaser -8.24 -7.92 To Be Over -8.05 -7.64 [{POST_SNAPBACK}][/a] Replaygain is only valid for measuring the loudness if all tracks have been normalized to the same level; I'd say we should always use 0dB. Then it tells the peak-to-average difference. Have you done that ? [a href="index.php?act=findpost&pid=264228"][{POST_SNAPBACK}][/a] I have For 'Sound Chaser', in order of release, here are the left and right channel peak amplitude-to-average RMS Power differences in dB, and the (average of L +R), after track normalization to 0 dB, using Audition:first CD release: 15.8* 16.96 (16.38) Yesyears boxed set: 16.92 16.4 (16.66) First remastered CD: 14.73 15.93 (15.33) Japanese HDCD: 12.53 11.58 (12.05) Latest remaster: 15.35 15.34 (15.35) Interestingly, the only version that doesn't show *any* visual evidence of flat-topping (clipped peaks) is the first one. I'm curious to know, how does 'old fashioned' clipping/limiting (analog) show up in a wavform visualization? Does it show up as flattops below 0 dB FS? Because that's what I see in 4 out of the five visualizations. Or does this come about from digitally clipped mastering that has then been backed off a little bit from FS? *for this one, I could not get the file to normalize to 0 dB; the normalized peak would be in the left channel which would go to -0.05 dB but no higher. Don't know why. You can view the raw data and the wavform screen captures [a href="http://www.m-ideas.com/sullivan/sc/Sound_Chaser.htm]here[/url].
