I am trying to deeply understand the various meter plugins I have and the Cubase meters. I have an audio test tone sine wave generated from a first class test tone generator website, definitely 1kHZ at -20 dbFS. The Cubase track meter shows input as -20dbFS. But the Stereo Out shows -23dbFS, as does the meter in the right zone. I don’t understand this. There are no inserts anywhere, and just in case the panners attenuate as some do I have disabled the panners.
A 3dB difference sounds to me very much like some sort of standards difference (AES17?), but why should there be a difference in the same mix console?
However, when I use the Steinberg TestGenerator plugin, the stereo out shows -20dbFS when the generator is set to -20dbFS. I can’t quite feel my way around this.
Apologies if this is a dumb question from a relative newbie.
