Hi There folks I see there's some neat playback features. If you press the letter p 3 or more times in the preferences you hear playback option. There is one in particular I question. It is called .mp3 gain. If the check box is checked there is the choice to normalize, apply .mp3 gain or .mp3 gain and clipping. There is another selection that says preferred source, track or album. There is a slider box that you can adjust how loud the normalization or what have you is, I keep this volume at 60 percent. Can anyone explain the options and what they actually mean and do please? Thanks.
