Thanks for the tip, a few people have now pointed that out. Since you've
brought it up again...

Looking at the waveform of an MP3 file isn't necessarily the same as looking
at the original waveform before it's been put through the data reduction
process (so-called MP3 "compression"). It depends on the data rate and the
codec used, too. Of course that's theory, speaking, because I have not tried
this. I know that audio data is removed, but I do not know how visible it is
on a scope.

(Now that I know about the CE and WinAmp scope views, I may try this out.
I'd like to see how much data gets thrown away at different bit rates, for
example. Compare different waveforms to see how each survives the MP3
encoding. That sort of thing, just out of curiosity.)

My apologies if this is all too off topic.
