Last post by Case -If tone://997 is a pure 997Hz sine wave that is used as reference point of dBFS (the zero point), then shouldn't that show up with a 0 *dBFS* reading?In that reference, sure. In the so called RMS+3 scale.
If a test file is published as -20dbFS, shouldn't that be rendered at -20dBFS?Depends who published it and what it's meant to show. For example the sine waves from soundonsound have peaks at -20 dBFS so showing peaks at -20 dBFS is very valid. True RMS for such sine is 3 dB lower, -23 dB, 'RMS+3' display would be -20 dB.
If you want a *dB* reading and rendering, activate the RMS+3 toggle.When the toggle is off, you show 'RMS+3' values. When it's enabled you show RMS+3+3 dB. And adding the FS for full scale is just an accuracy increase, because dB alone doesn't tell what it is relative to. All values are of course relative to the digital full scale.
