I use this track splitting approach to test if a renderer supports gapless playback (can test multiple track transitions quickly) where I use sox to perfom the split:

Code:

sox 01.01.flac 02.%2n.flac trim 0 20 : newfile : restart

EDIT: Looking at wikipedia MP3Gain appears to edit the audio itself (information on how to undo the changes are stored in the tags, not the gain itself), so there's nothing to apply in MinimServer.

That is incorrect. MP3Gain does not modify the file, but adds the information as an APE tag incl. undo information. It is a nifty little program.
