I received my Edirol R1 last week, and am pretty happy with it so far... except for one thing. For some reason, I'm getting 16 to 30hz -56 to -49db noise (with about a 12khz 15db signal riding on top) when I bring any file (mp3 or wav) produced by the Edirol into an audio editor (I'm using Sound Forge 7.0). I can hear it with Winamp, Windows media player, Real Player, or any other audio player I can think of. For some reason, though, if I play the file using the Edirol (i.e., play audio directly from the phones output with effects disabled) this noise is not present. Put another way, I get less noise when I make a 2nd generation analog recording into my computer from the Edirol's phones output than I get when I transfer the 1st generation file directly from the Edirol's compact flash into my computer. Anyone know why this is the case?
