Double the voltage

    I created 2 audio tracks and inserted the test oscillator on both tracks, both plug-ins had exactly the same settings sine/1000Hz/-12dB. If I muted one of the plug-ins the master bus read -12dB, as I suspected it would, but when I un muted the other the master bus read -5.9dB? I'm confused, if I double the voltage (I assume that's what this is emulating) then I should get a rise of 6dB correct? What am I missing here? :confused:

    P.S I was under the impression the master bus should read -6dB

    This level indication isn't a precision instrument. My output shows –5.9 too but an inserted Logic level meter shows –6.0 and Inspector XL shows –5.97. My Spectre isn't connected at the moment.

    You posted in the "Mastering" forum. For mastering I wouldn't trust a DAWs level indications but rather go for specialized software like Spectre or Spectrafoo. Or stay well below the limit ;)
