Hi,
I use the attached ACX Master macro with Audacity 2.3.2 on Linux Mint.
It uses the values specified in the Audiobook Mastering Suite thread (the Low Frequency Rolloff for Speech filter length is 5007 by slider adjustment).
I added a Select All at the start because I process complete segments but that can be removed if you prefer.
NOTE: Be careful of using the Macros dialog Edit… button. This seems to cause a bugreport generation and you don’t actually need that button to insert or remove new entries.
ATB,
Neil
