        >Or did you mean the wave phase?

Yes. To be precise, the phase of the waves making up the flattened envelope
are shifted relative to each other, thus modifying the resultant envelope. A
bit like the effects of FM through a bandpass filter with poor group delay.

>Is group delay not automatically "differential"?

I don't think so - you can have a flat group delay characteristic, where's
there's no 'differential' but there is delay.
