Metering Discrepancy - SuperVision vs LUFs/Audio output meters

When I use/compare readings of SuperVision, Voxengo Span and Brickwall Limiter plugins, they all agree with one another - and they all disagree with the audio output meter and right sidebar LUFS meter, which seem to give higher values - ie the LUFs meter and Audio output meter will indicate signal above 0db (ie big red bar) while the aforementioned three plugins will be showing say -2db (as set on the limiter) and the LUFS figure in Supervision is lower than the LUFS meter. Can anyone tell me why this is so?

Hi @stratman58,
Many thanks for your feedback. Could you give us more information about what version of Cubase you are using, as well as which platform and how you are making the measurements exactly?
Do you also observe such difference with the Statistics Window?

Thanks in advance!

Hi, I’m using Cubase 11 Pro on MacOS 10.15.7. I’m zeroing everything and running through a track, with the Supervision, Brickwall Limiter and Voxengo Span as the last plug-ins on the stereo output. I’m comparing with the LUFS meter in the right sidebar, and the stereo output meter, which both showed higher readings than the three plug-ins. I’ve just opened a file and run through it - now I get the reverse! - the LUFS meter is about 2dB lower than the three plug-ins, which all, however, still ‘agree’ with one another.

If I select the stereo out channel and open the statistics window I see the attached:

On your image the Stereo Out fader isn’t even at 0…


@stratman58 No answer ? That probably says it all :laughing:

Hi, sorry been having ongoing problems logging in - yes the two meters align much better now with the fader at zero!! Thanks for your help
