I really like Audacity’s smooth and crisp backend. But there are some plugins that I use daily in Audition 3.0 that Audacity is missing. I’m confident that Audacity probably has it, I just haven’t strung together the correct search string.
Specifically, I’m looking for ‘Multiband Compressor’ and ‘Stretch’. I’ll attach screenshots so maybe someone knows of builtins or alternatives.
Audacity does not (yet) have a multi-band compressor. You could perhaps try the “Calf” plug-ins, though it’s a bit hit and miss regarding compatible versions. If you can’t get the Calf plug-ins to work, search Google for an alternative LV2 multi-band compressor.
Audacity has various types of “stretch” - it’s worth looking at all of them to see what they do:
https://manual.audacityteam.org/man/change_speed.html
https://manual.audacityteam.org/man/change_tempo.html
https://manual.audacityteam.org/man/change_pitch.html
https://manual.audacityteam.org/man/sliding_stretch.html
https://manual.audacityteam.org/man/paulstretch.html
The thing I was specifically looking for but was unable to find in regards to stretch, was the ability to preserve pitch, and just input a value for seconds all on one screen. I make 30 seconds sound bites over and over again and that particular tool makes the workflow much quicker. I was able to mock the multiband compressor using the EQ, so that’s not quite as important as finding a much better stretch tool.
This is exactly what I was looking for. Thanks. Is there a way to set SEC marker as well?
What is “SEC marker”?
It’s metadata
SEC tone, SEC timer, EOD timer, etc.
Audacity does not support the CART chunk.
(It seems that very few audio editors other than Adobe Audition do)
Well that’s unfortunate, but not game breaking. Thanks man
Hi. LSP has a very nice Multiband Compressor
https://lsp-plug.in/?page=manuals§ion=mb_compressor_stereo
The down side is Audacity does not support LSP plugins
If the Multiband Compressor is the last thing in your editing chain, you can use Carla to load the plugin and then make a weird routing signal to connect the output to the compressor and the output of the compressor to the input again and play/record in audacity the compressed file:
Calf Multiband Compressor running in Audacity 2.4.2
Click on the “Manage” button and select “Options > Enable graphical interface”.
Then close the interface and relaunch the effect.
It was enabled 
I disabled it, closed the effect, relaunch, and it was the same.
I enabled it, closed, relaunch and nothing changed.
Any ideas?
Ubuntu studio 20.04. Audacity 2.4.2 from: lp_ppa_ubuntuhandbook1_audacity-focal-main (Should I try another version/Source?)
(By the way. I can enable the LSP plugins on this version, but the GUI was also missing)
If the pretty GUI is enabled but does not work with Audacity, then Audacity falls back on the basic UI (which is what you are seeing).
I’m using:
Xubuntu 18.04 LTS
calf-plugins 0.0.60-5
