Audiobook Mastering Macro fails on Audacity 3.6.0-X86_64 and Audacity 3.6.1-x86_64.
Audacity 3.5.1-x86_64, Audacity 3.3.2-x86_64 and before succeed as far as I checked.
Apply Effect > Loudness Normalization… to a plain speech track at Normalize RMS to -20dB.
The track will settle at an RMS value of -20dB.
Edit > Undo.
Tools > Apply Macro > Audiobook-Mastering-Macro to a voice track in Audacity 3.5.1 or before and you get -20dB loudness. If you apply the macro to 3.6.0 or 3.6.1, the track will settle in at -16dB RMS, too loud, not -20dB.
Are you using Compressor or Limiter in that ACX tool Koz?
If so, mote that Compressor and Limiter were replaced with new effects (but with the same name) for 3.6 - and the old parameter settings used in Macros with these commands no longer work.
So you would need to reset those for 3.6 onwards - and you may want to have two versions of the tool, one for 3.5 and earlier the other for 3.6 and later.
Mastering uses Loudness Normalization and Limiter. No Compressor.
Makes my head hurt.
Side question: You’re one of the Windows Elves, right? I’ve been using “Ctl/Alt/Del > Hold Shift > Shut Down > OK” to execute a Clean Windows Shutdown. I’m flying blind. Did I get close?
The new Limiter and Compressor are basically the same effect under-the-hood - the basic differences is that the Compressor has more parameters and more functionality.
I make a clean windows shutdown by:
Click on the Windows icon at bottom left of screen
Click on the Power icon - the bottom one, the circle with the little vertical bar at the top
