#Additional new features


Batch Processing

A collection of features added to Audacity for 2.3.0 are related. They come from a project to improve batch processing. Listed here, they are described in more detail in following sections. The project improved:

  • Macros feature, for repetitive tasks that can be done without using a scripting language.
  • Scripting using a scripting language such as Python running outside Audacity.
  • The project led to the new tools menu, and the new scriptables sub menu with many new commands.


Macros command replaces Chains

The old Chains command (for batch processing and effect automation) has been replaced by an extended Tools > Macros... command. Macros can do everything that Chains did before, however there are now many more commands it can use - including new commands that have been created specially for batch processing.

  • We have changed the user interface. We have integrated the functionality so that you now can view, edit and apply your macros from the same single dialog window, simplifying the usage of macros.

    • Re-setting the parameters for commands in macros has been simplified. Now double clicking on a command in a displayed chain will pop up the parameter settings dialog for that command.
    • The dialog window can be reduced in size and scope by using the Shrink button. This reduced 'Macro Palette' dialog can apply macros to your project, but does not edit them.
    • Many more commands are now available to Macros. Previously the commands were mostly effects. Now nearly all menu items are included.


New Tools menu

A new menu item Tools has been created, with customizable tools.

The Tools Menu contains customisable toolsThe Extra menu provides access to additional Commands that are not available in the normal default Audacity menusThe Help Menu lets you find out more about the Audacity application and how to use it. It also includes some diagnostic tools.Enable or disable particular Effects, Generators and AnalyzersCreates a new Macro or edits an existing MacroDisplays a menu with list of all your MacrosReset most settings back to the default valuesA tool, mainly used in documentation, to capture screenshots of AudacityA tool for measuring the performance of one part of AudacityBrings up a dialog where you can enter Nyquist commandsA Nyquist plug-in that simplifies the installation of other Nyquist plug-insPlaces labels in a long track so as to divide it into smaller, equally sized segmentsReads the values of successive samples from the selected audio and prints this data to a plain text, CSV or HTML fileReads numeric values from a plain ASCII text file and creates a PCM sample for each numeric value readThe MenusToolsMenu.png

Help Buttons

Help buttons Help Button have been added to the Macros full and reduced dialogs, to some error message dialogs and to some other dialogs that did not previously have them.


Half-wave option for collapsed tracks

For collapsed tracks there is now an option settable in Tracks Preferences to show the upper half of the wave display only in order to show a little more detail.

Increased legibility of trackname display

Sliding Stretch replace Sliding Time Scale / Pitch Shift

The effect that was formerly named "Sliding Time Scale / Pitch Shift" has been remave to "Sliding Stretch" for this release.

This is a simple name change, no other changes have been made to the effect. The change has been made mainly to reduce cerbosity in the menu along with an attempt to make the command name more meaningful.


Overwriting existing projects

In response to many user requests for this we have changed Audacity so that is now possible to overwrite pre-existing projects with File > Save Project or File > Save Project As....

In doing so you will get the following warning message and please note that for safety reasons this warning cannot be turned off.
