This sure were interesting if we discussed the loudness war. But we're not.
As to the math... RG values per disc might be mathematically more exact but this leads to the following problem: A two disc album I examined in my collection has the following RG values Disc 1 gain: -8.05 dB Disc 2 gain: -5.33 dB Album gain: -7.24 dB Track gain last track disc 1: -7.71 dB Track gain first track disc 2: -7.11 dB If we listen to this album using disc gain we will have a gain jump between disc 1 and 2 of 2.72 dB. The first track of disc 2 will be played back louder than the last track of disc 1 even though the track is actually quieter (according to track gain). Using album gain both discs will be played back with -7.24 dB. This will preserve the natural variance between the two tracks. Who's gonna adjust the volume now? Your seemingly impeccable "my way is better" approach isn't the perfect solution in all cases. Here's my more differentiated approach on how to apply RG values: Albums... An album is a continous piece of work consisting of tracks. An album can span one or more physical media, depending on its length. Album gain should be applied to the whole album, regardless of number of physical media. Box sets... comprise of multiple albums or variations of the same album. A box set consisting of a studio and live version is considered two albums. A rerelease of two or more original albums in one package are multiple albums. Album gain should be applied per album in the box set. Not per disc because one album in the box set can still be more than one disc! Compilations... are borderline cases because they are not really albums but collections of individual tracks. I'm not sure if album gain should be applied to them at all since there is no variance between tracks that needs to be preserved. IMO a compilation is basically the same as listening to a random mix where track gain should be used. -s. -- slimpy ------------------------------------------------------------------------ slimpy's Profile: http://forums.slimdevices.com/member.php?userid=1524 View this thread: http://forums.slimdevices.com/showthread.php?t=57543 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
