If you look at the discussion http://www.hydrogenaudio.org/forums/index.php?showtopic=101182&st=0&gopid=836460&#entry836460, it shows that when MP3Gain does it's adjustment, it does actually store ReplayGain info in the APE tag, as well as changes the global gain field in each frame header.

We don't even parse APE tags.

So where do you read the ReplayGain info from then??

In the case of MP3, we use ID3v2.  Its different for each format though, and some do support APEv2:

Thanks for your help.
So if those APE fields appeared in the ID3 tag with the same field names, then Rockbox would use this as the ReplayGain for that MP3, regardless of whether or not it has been gained by MP3Gain?

APE anything on MP3 is always ignored.  Replaygain tags in ID3v2 are used if you've enabled replaygain.  Simple as that.
