iTunes match tracks different volumes from the same album
Using iTunes Match. Among other reported problems, after downloading Matched tracks to my master iTunes library to replace lower bitrate versions, the new tracks from the same album have different loudness or volumes between the tracks. Is this because iTunes Match is matching the songs to different versions of the same album? Where some albums have been 'remastered' or such, that the recorded volume between the albums is different? But instead of matching tracks to the same version of the album, some are being matched to different versions of the same album?
Quite offputting to listen to a single album where track to track loudness changes suddenly.
PS, I'm not using SoundCheck on my Mac.
