Wrong. Decibels are an expression of the RATIO of two powers,
OR two voltages, and, in most applications, the method being
used (power or voltage ratios) is usually specified, except
in some audiophool crap as marketing hype. "Peak Envelope
Power", indeed.

Oh, go plonk your own self.

Good Luck!

he had followups set to alt.null, as per usual - I found out that
there isn't any such thing. It's dead already. Apparently, he
