Hello,

        I know that ATRAC compresses the audio somewhat by removing all
the frequencies that the human ear cannot hear.  I have also found out
another way that it might compress the audio.  I recorded one of my
lectures onto MD and then transferred it onto as .wav file on my
computer.  When I zoomed into the waveform of the sound, there wasn't a
continuous wave, there were many little 'packets of sound'.  Now I think
that the MD must also take the 'packets' so fast that we can not
distinguish them as seperate (kind of like the 24 frames per second in a
movie).  What do other people think?

Al.
