I see ReplayGain is a feature. I’m using beta 31 and have ticked the Enable ReplayGain in preferences. I’m not sure how it works but I have noticed quote a change in volume across albums for different artists
I also use JRiver and they use the integrated LUFS method which works very well for a consistent volume across different tracks. If playing an album it can apply the gain adjustment on a global level, i.e. all tracks are adjusted by the same amount. If it’s a playlist with tracks from different albums then it works on a per track level. JRiver sets the target loudness to R126 -23LUFS. I think something between -16 to -14 LUFS would be suitable for most material, in-keeping with streaming spec.
