I searched and found this thread: http://forum.powerampapp.com/index.php?/topic/1316-soundcheck-option-available/page__p__5259__hl__normalization__fromsearch__1#entry5259 However, it's over a year old and if I understand correctly Poweramp now supports Replay Gain for normalization. Is there a chance that Apple's Sound Check will be supported? Winamp does this by converting Sound Check tags to Replay Gain when syncing. I prefer iTunes over Winamp and Foobar2k, but that's another discussion. /iPhone user, looking over the fence for alternatives
