I also do not know what you mean by the terms "envelope" and
"waveform" in this context.
Envelope is a line drawn through the peaks of every cycle over whatever
period of time you want to look at. In the context that y'all are
arguing about here, it would likely be a whole song. If it's darn near a
straight line with no squiggles, that's what we call "toothpaste tube"
limiting. The amplitude value may not be full scale but it might as well
be - it won't sound any worse than if the envelope is flat-topped at -6
dBFS, but it'll be louder.
The waveform is what you see when you blow up the display so that you
can see individual cycles. You can see the peak level of each cycle, and
whatever goes up, comes down. It's the peaks of the waveform that you
connect to get the envelope.
