I always seem to get a tiny blip of noise at the very begining of every track...just a speck - and its so close the beginning of the track that often I dont see it in an editor. Sometimes I'll go to normalize a track - and nothing happens...focus on the beginning and trim off that spec - and then the normalize function doesnt have to deal with the false peak caused by the niose - and works as expected.
Both of my current working nomads do this...its not really a problem - just an observation.
