    Is 0 (zero) VU the same as 0 in the digital rehlm?

    And also, what is 0 in the digital rehlm, is it db?

    I'm sure there must be tons of threads on this subject, but to make it quick.

    With a reference signal of 1kHz sine 0VU=-20dBFS in the US and -18dBFS in Europe.

    Be careful, a musical signal will register differently. that is because the sine wave of the 1kHz tone has the same energy in its positive and negative half. A "musical" signal is a different story.

    A VU reacts very slowly (much like your ears) and a peakmeter much faster. Some digital meters show you the instant value of the sample.
    They will never agree with e/o and that's the point. Very nice to have both side by side because they give you an idea of loudness, versus a technical reading that helps you prevent overshoots.

    In digital you abbreviate dBFS FS stands for Full Scale.
