I have one album where various track volumes are noticeably different. I’d like to use ReplayGain to level them all out, but have a few questions about how ReplayGain is implemented in A+:
1.) In Audirvana Preferences/Audio Volume there is a “ReplayGain loudness normalization” option. Is this option invoked when the “Recompute ReplayGain” button is pressed for a given track or album, i.e., is it used to help generate the ReplayGain parameters, or is it used only for playback?
2.) Referring to #1, if the “ReplayGain loudness normalization” option is used for generation of ReplayGain parameters, how does each option affect the ReplayGain parameters that are calculated for each track or album?
3.) Referring to #1, if the “ReplayGain loudness normalization” option is used for playback, how does each option invoke the ReplayGain parameters, i.e. how is playback affected by each?
4.) For all of the other albums for which I have not computed ReplayGain parameters, do the “ReplayGain loudness normalization” options have any effect at all?
Thanks for any help.
