Is there a "Repeat Last Command" shortcut?

I’m just familiarizing myself with Audacity, so in terms of using the program itself I’m a newbie. However, I’ve done audio editing for many years. I do a lot of VO editing and because of the nature of that work I set up short cut keys including a “repeat last command” short cut. It’s a big help when some of the functions are used again and again.

My question is, is there a way in Audacity to set up a “Repeat the Last Command” or Repeat the Last Function" shortcut key(s)?

The command I want to repeat could be any number of things; examples: lower the volume by 6dB, fade a selection in, fade a selection out, insert 3 seconds of silence, etc. I have checked tutorials and searched this forum but can’t seem to find the answer.

I am using a Mac Book Pro running Yosemite OS 10.10.4
My Audacity version is 2.0.6

Any assistance would be appreciated.

That’s only five versions out of date.

Get Audacity 2.1.1.

Some of what you want is buried in 2.1.0 effects management. Because of the inability of Audacity to apply effects in real time, it is required that you repeat effects multiple times to get them right. One version of Audacity had the effects in hierarchy and tree structure because it was pretty. That tripled production time, increased errors and lasted exactly one version.

I advocated the ability to create a hot list of effects used all the time so as not to have to plow through the whole pile repeatedly. I haven’t done any actual work with it, but I think the newest Effects Management is a generous step in resolving this.

Scroll down to Manage:

There is a way to memorize processes. Audacity has Chains which is its version of Batch.


The effects in the Effect menu can be repeated by pressing Ctrl+R (Windows) - it’s probably Cmd+R on the Mac.
The item can also be found right under “Manage” in the Effect menu.
It uses the plug-in’s last settings without the GUI popping up again.

Note: it won’t work for Analyze or Generate Plug-ins, thus, you can’t repeatedly insert silence for instance. However, there’s always the workaround with copying the generated silence and paste it in other places.


Thanks guys. I have downloaded the latest version, read some help pages and played with a few things. I won’t have the exact same procedures and functionality in using commands that I’ve had in programs like Adobe Audition, but once I get familiar with Audacity I’m sure it will address my needs just fine. So far it looks like a great option. Then of course, it’s a matter of muscle memory.
