Volume Unit
In the analog field, the V.U. concept deals with different definitions. Firstly, 0 dBm gives the level of a signal outputing a power of 1 mW on a 600 ohms line. Secondly, by default, a real-life analog VU-meter displays 0dB for a +4 dBm sinus voltage.

In the digital field, these definitions don't make sense anymore. The maximum signal level is +1.0 (means 0dB Peak) and cannot be related to a voltage notion or whatever value depending on D/A converters. Then, to introduce a VU-metering tool in the digital field, we first had to define a new standard.

Even if VB-Audio's VU-Meters are fully configurable, the ANALOG VB-Audio VU-Meters, by default, displays 0dB when they receive a sinus signal at -4dB peak. This zero point was defined in order to use the precision of the VU-meter scale in the best way, and also to define a coherent measurement of signal power taking digital audio limitations into account.

Now that we have defined a standard, the VU-meter can take a strict measurement of the signal's RMS level. The final behaviour of the VU-meter is based upon ballistic parameters (attack/release time) in order to emulate the behavior of a hardware needle VU-meter when measuring a complex signal (not only sinus signal).

The interest of VB-Audio's digital VU-meter is the possibility to evaluate the power of a bound signal, that is to say that it will match its own representation on a digital medium. That's why we shall use the VU-meter after limiting or lopping the signal (removing peaks).
