I'd be really interested in this too, IF I'm not modifying the file. Anyone have any experience with this?
One week ago I moved to MM and looked for ReplayGain settings, but could not find it
However, yesterday, when configuring
Cantata, I found ability to enable ReplayGain through its interface, in the settings related to playback.
Good news is that it works, so now I can listen to multiple albums on headphones without adjusting the volume each time
Bad news is that enabling ReplayGain is not persistent, it will change to None after BDP restart
To give example, difference in recording levels between two albums I am just listening right now is about 7db: Chris - Making Sense (foobar calculated) ReplayGain of -5db and Children of Nova - The Complexity of Light ReplayGain of -12. The difference is quite noticeable and creates discomfort especially when listening to headphones
L.E. I would mention there are two ReplayGain options for converters, one is "ReplyGain" and second is "ReplyGain (apply)", the first one is to be used, as it writes tags with the ReplyGain information, while the second alters the file.
