Used values in order

You may change the order of the values with the up/down button and/or add/remove some of them with the left/right arrow buttons or by double-clicking.
Preamp for tracks with Replay Gain information
Additionally adjust the Replay Gain infos of the songs by this factor. You might like values around +2 dB to get reasonable loudness.
Preamp for other tracks
Adjust the gain of songs without matching Replay Gain information by this value. You might want to use negative values here to fight against the loudness war.
