to not accept the LUFS Meter as a plug-in under OS X
prior to OS X 10.11 (El Capitan).
LUFS Meter 1.4.2
April 11, 2016
Changed the installers on OS X and Windows such
that the previous plug-in files get deleted before
they get replaced. Otherwise it happened on OS X as
well as on Windows that even though the files got
replaced, they kept the creation and modification
date from the previous version. Some hosts (like
Pro Tools) do use the creation date flag to
determine if they need to rescan a plug-in.

instances of the same sync group.
Improved the performance of the loudness measurement.
Support for Pro Tools Audio Suite offline analyze.
Support for offline analysis in Reaper via its
Fast scrolling of the history graphs when
processing faster than realtime.
Updated the factory presets.
Added denormalization (higher CPU usage on silence)
Stability improvements when the host changes the
number of channels while processing.
A single click anywhere on the track of the
adjustment fader doesn't make it jump to that
loudness anymore. This could have resulted in
dangerously high volume increases.
Fixed: Alt-Click to reset the adjustment fader to 0
LU didn't work in Cubase.
Replaced the web browser component in the update
notificator with a simple text editor to display
the changes. The embedded web browser had rarely
caused issues on OS X 10.10.

New sync groups. Multiple LUFS Meters can now be
synced in groups.
New adjustment power button (or bypass, if you
like). Can be synced.
New: The LRA value can optionally be hold as soon
as silence occurs. This makes it easier to read it
after a measurement. Without this, especially on
short measurement times, the LRA will slightly increase
New automatic update check.
New online unlocking. If your audio computer is
connected to the Internet, you can unlock the
Discounted or the full LUFS Meter from within the
The token generator needed to be changed. Before it
could happen that the 32 bit and the 64 bit
versions on Windows showed different tokens. A
similar discrepance occurred on OS X with Garage
Band and everything else. -> Unfortunately, you
need to activate your LUFS Meter again. If you are
affected, a dialog window inside of the LUFS Meter will
pop up and guide you through the process.
Stability improvements if one instance of the LUFS
Meter is run on multiple threads. This mainly
affects Final Cut Pro X.
