An Australian promo cd service i subscribe to has all files set to around 92dB gain. I think they do this because many jukebox owners subscribe to the same cd series & they want similar volume levels from song to song.When i convert the files to mp3 i raise the gain so the track volume is maximised but just under clipping point. Most tracks i adjust to 97dB, which is quite a significant gain increase. I dont want to run the tracks at the original low gain levels of the cd as they dont sound as good especially the lower audio signals of a recording.
