Audacity 2.3.3

In early October Apple released its latest operating system 10.15.x known as Catalina.

Audacity is not officially supported yet to run under Catalina. It appears to launch and run fine but it fails to record from the microphone (or external USB device) yielding only a flat-line silent recording. This is a permissions issue regarding access to the microphone (recording input) and something which we need to explore further.

Fortunately there is a workaround ...

if you have updated to Catalina and still need to use Audacity for recording as well as all its other functionality:

1) Go to Applications > Utilities

2) Launch

3) in the Terminal dialog type the following command following command:

open /Applications/

This will open Audacity and then Terminal will actually ask for the correct permissions.

this assume that Audacity is stored in your Applications folder. If it is somewhere else, you will need to change the path in the above command: open /*location of audacity*/ When you first try to record, you will be asked to grant access to the microphone - similar happened in 1.14 Mojave - but microphone access permissions granted in Mojave do not pass through to Catalina. Once you have granted this access in Catalina you should not be asked for it again when relaunching Audacity with this workaround method.

If you leave Audacity active (black dot) in the bottom dock you can just relaunch from the Audacity logo.

If you totally quit Audacity you will need to relaunch from the Terminal app again every time.

Finally: credit for providing this useful workaround must go to Forum user noraa - very much appreciated, thanks Noraa.

Audacity 2.3.3 was released on ----- May 2019.

Changes and improvements since previous version

Audacity 2.3.3 replaces all previous versions.

  • Over 150 bugs fixed since 2.3.2.

Full details of new features in the visual guide to New features in Audacity 2.3.3

Supported Platforms


  • Audacity 2.3.3 requires the CPU to support the SSE2 instruction set which should be available on any Intel hardware produced after 2001 and any AMD hardware produced after 2003.

    • To check what SSE levels your CPU supports, you can install CPU-Z.

    • If your hardware only supports SSE, you may download Audacity 2.0.6 see the Legacy Windows page on the Audacity Website.

  • 2.3.3 does not support Windows XP.

    • You may try 2.2.2 on XP, but it is unsupported.

macOS / Mac OS X


  • Linux support is tested on Ubuntu Linux.

    • Audacity may compile on Gentoo, Debian, Mint.

    • Audacity does not currently compile on SuSE Linux.

Interactive Buglist Page

We probably track more bugs than you are interested in...

On the dynamic buglist page you can select to view:

  • Complete list of bugs in 2.3.2 that we have fixed for 2.3.3

  • Known bugs on the OS you use Mac, Windows or Linux.

  • Known bugs to do with accessibility or localization.

  • Workarounds for some bugs.

  • Serious bugs and less serious bugs.

We do use this detail in our own QA work.

Highlighted Issues

  • Below are listed what we believe are the most common and important issues with 2.3.3 for most users.

macOS Catalina

  • We don't properly support mac Catalina yet. A workaround must be used to get recording to work at all.


  • Far less of Audacity is properly accessible to visually impaired users than we would like. Currently the best supported platform for accessibility is Windows. We lost a lot of custom accessibility programming when we had to move to a more recent version of the wxWidgets library.


  • Audacity is only partially translated in many languages. We also have some issues, for example, with Right-To-Left Languages.
