This page is an overview of prominent new functionality that has been introduced in Audacity 3.0.1

Version 3.0.1 is primarily a maintenance release for bugfixes.


  1. Overview
  2. Manage Macros improvements
  3. 34 Bug Fixes


Audacity 3.0.1 is about bugfixes for Audacity 3.0.0. Some bugs which didn't show up in our testing of 3.0.0 became apparent once 3.0.0 was being used by more users. We wanted to fix these and also to get more diagnostic information about what goes wrong when SQLite (the database we use) cannot read or write a file. So we added more informative diagnostics for when there is an error.

One cluster of bugs we fixed relates to Unicode. Unicode is a system for representing many non-English letters and symbols. We, Microsoft and Apple all have made mistakes with Unicode that affected Audacity 3.0.0. One problem we tracked during 3.0.0 turned out to be a Windows update issue with Unicode input, which was resolved by a later Windows update. Disappearing checkmarks in macOS Big Sur release turned out to be a Unicode issue, believed to be in Apple code, which we now work around in 3.0.1. A mistake we made with Unicode prevented Audacity working in Korean and Japanese.

Some of our bug-fixes are small changes in areas where the previous Audacity behaviour was not as we wanted. 3.0.1 may only be a 'point' release, but we think it's one most people using 3.0.0 will want.

Error: Failed to open the project database

There is a mysterious error which only occurs occasionally (and we cannot reproduce it on demand) but is currently leaving us mystified. Usually this seems to occur when you are trying to import an audio file but there may be other use cases. It does not appear to be causing users to experience data loss or damaged projects. It is this bug: Bug 2700 - "Failed to open the project database"

For 3.0.1 we have added a Show Log button to this error message so we can hopefully gather more information about this to aid the developers in analyzing the issue. If you do encounter this issue please press the log button to generate the log and send us a copy of the screenshot to the Audacity Forum. The message has been changed to "The project's database failed to reopen"

Bulb icon This can normally be resolved by simply exiting Audacity, relaunching and then making the required import of an audio file.

False recovery offered on launch

This is another mysterious issue which only occurs very occasionally and is foxing us.

Sometimes after exiting Audacity without saving the project when offered, on the next relaunch a false recovery can be offered when there is really nothing to be recovered as no crash has occurred to cause this.

This is Bug 2732 Faux recovery offered on launch (very moonphase). If you encounter this and accept this recovery it "recovers" an empty project and no damage is done.

Our current thinking is that these two errors may be linked so that if you get this false recovery and then try to import audio you may well get the "The project's database failed to reopen" warning too.

Manage Macros improvements

The Manage Macros dialog has been improved for this release:

  1. The Cancel button has been removed
  2. It is replaced with a Close button
  3. A new Save button has been added to enable you to save the results of editing a Macro.
The Save button is grayed-out until you edit a Macro.
