How to use PerfectTUNES to check if Replay Gain was applied when ripping?

[Fog_Chaser]

I wanted to check if Replay Gain was applied to metadata when my discs were ripped. In PerfectTUNES is there way to check that using the ID Tags function. I can see it as an option on pull down menu when Browse by File Folders and Album Edit mode. It's unclear if I select it (Replay Gain) whether it applies Replay Gain or it is allowing me to see if it was applied.

Since posting I went back into the ID Tags section and right clicked on a song and can see drop down with Edit Tag and now I can see additional info. I can see what appears to be Replay Gain applied to both song and Album. Is this strictly correct? If I want to have a bit for bit copy of a CD without any changes (either embedded or directed by metadata) shouldn't Replay Gain be at zero db or am I missing something?

Run the ReplayGain program from PerfectTUNES control center

no. You are misunderstanding the purpose of RG Tags. Replaygain tags have nothing to do with having a bit perfect rip of the CD. The tags are simply used by a RG aware player to adjust volume during playback.
