To DC,
my WL tools are giving me this information.

Aha, you mean "Wavelab". Well, its VU meter is 3 dB off from the AES standard. VU and peak meter should read the same with sine wave to meet the AES spec AND to meet the practices of the last 60 years! For example, with sine wave at -15 dBFS on the peak meter, it should read -15 dBFS on the VU meter as well...
Add three dB to the Wavelab VU reading to meet the standard.
(Stand by for a plethora of inquiries from readers discussing square roots and rms to peak ratios.) The answer in short: It's a REFERENCE, it's a decibel reference.... The reference is that BY DEFINITION, with a sine wave, 0 dB should read the same on all types of detectors, RMS, averaging, quasi peak, and peak. That's where they're all supposed to be calibrated.
