I might should note here that the particular protocol you set for sound
out has a significant effect on the sound you get. In OSX you have a
choice in Peak of Core Audio (with some options), or two versions of
Hal. At least in my G4. Depending on those settings my mac may play the
original to sound just like the flawed peak file, or just like the spark
file. And some settings don't work right at all.
Sounds like it's different in a iMac, we know from the discussion a
while back that it's handling of resampling is quite different from my
g4, but you might want to play with whatever settings you find in the
Audio>Sound Out menu choice in Peak. Also check that against what the
Quicktime Player gets.
