Can't get LoudnessNormalization working

[JohnMayo]

I’m trying to automate parts of my Audacity workflow in Python. I’m using the pipe_test.py example code as the basis for my code. I’m on Windows 11 using Audacity 3.4.1

I am trying to run Loudness Normalization on a track using the following command:

rmslevel = -20
normalizeto = 0
do_command(f’LoudnessNormalization: RMSLevel={rmslevel} NormalizeTo={normalizeto}')

I get the “BatchCommand finished: OK” response from do_command but the track doesn’t change in Audacity.

This is what I’m trying to automate for the current selection:

I would appreciate some help. Thanks.

I’m trying to automate parts of my Audacity workflow in Python…

I get the “BatchCommand finished: OK” response from do_command but the track doesn’t change in Audacity.

So I don’t do much with Python (or with Loudness Normalization), but I tried this Macro command:

LoudnessNormalization:NormalizeTo=“0” RMSLevel=“-20”

and it altered my audio. Perhaps you will find a clue in there…

Thanks, I’ll try that once I can get the named pipes to Audacity to work reliably for me (Different Errors running pipe test - #12 by JohnMayo).
