Edit Steps in the Macro
Edit Steps lists the sequence of commands in order of first to last (End) for the Macro selected in the "Select Macros" box to left.
- The Macro can include a number of common Audacity functions and effects to be executed in any order you specify.
- To create an audio file as part of the Macro process you must include an "Export" command (such as Export as WAV).
- The Export command will use the settings you used that last time you used the same command from the menu command, or default settings if you have never used that command from the menu.
- In many cases the parameters for each command in the Macro can be specified within the Manage Macros dialog.
- Add or remove commands for the selected Macro
- Change the order in which the commands execute in the Macro
- Edit the parameters for some effects in the Macro
- : Insert a new command into the list
- : Edit the parameters of the currently selected command
- : Delete the currently selected command in the list
- : Move the currently selected command up in the list
- : Move the currently selected command down in the list
- : This button is only active when the Audacity supplied Macros are selected in the "Select Macros" list on the left, and will reset the Macro to its default values.
Editing an existing command
To edit an existing command double-click it, or use the Up or Down keyboard arrow to select it then press Space. The parameter settings dialog for that command will be displayed.
Inserting a new command
To insert a new command in a Macro, left-click or use the Up or Down keyboard arrow to select an existing command. The new command to be inserted will be placed above this selected command. Then press.
- The "Select Command" dialog appears, listing all the available commands. Double-click a command from the list to insert it in the "Command" box, as shown in the image below after inserting "Normalize".
- Alternatively, use the Up or Down keyboard arrow to select the command, then press Space.
- Some 'scriptable' commands are particularly useful for Macros. See these pages for details:
- If the command has editable parameters, the button will be active. Clicking this button will bring up the dialog box for the effect where you can set the parameters as if you were applying the standalone effect.
- If you have previously created user presets for an effect you can use the to select one for use with that effect in the Macro.
- Choose in the effect dialog to accept the parameters you entered, or to revert to the default parameters.
- Choose in the "Select Command" dialog to add the command to the Macro.
Macro Command Parameters
Commands that call Effects, Generators, Analyzers or Tools, use the same familiar graphical interface (GUI) as appears when they are used from the normal top level menus.
This example shows the "Set Track Status" command.
- The tick boxes on the left determines whether a feature should be used. When not selected, that feature does nothing.
- The second tick box determines whether the feature is set to "on" or "off".
- The track name will not be changed
- Track selectedness will be set to "not selected"
- Track focus will be set to "focused"
Selections in Macros applied to Project
Macros will work on pre-existing selections you make in your project prior to running the Macro. But the selection can be over-ridden by your Macro itself as there are Macro commands available to effect selections in the audio.
- In particular All(Select All) will select the entire project
- Select which is parameterizable (see the provided Fade Ends Macro for an example where the first and last one seconds of the audio are selected for the fades).
|If you want to select all tracks, maintaining your current time selection, use "Select: First=0 Last=100". It will not waste time twiddling its thumbs on the tracks that are not there.|
Selections in Macros applied to Files
When applying a Macro to files there is no pre-existing selection so you will need to create a selection in the Macro if your Macro requires audio to be selected to act on (and most Macros do).
Commands for Exporting audio files
- There are four basic export commands available: Export as WAV, Export as MP3, Export as FLAC and Export as Ogg.
- See Apply Macro for details of naming and location of exported files.
|Parameters for export formats cannot be set in "Manage Macros". To configure export parameters for the Macro, click Export Audio Dialog, click , set the parameters, press then the export. An audio track must be on screen in order to open the Export Audio Dialog.to access the|
Special Export command
- Export2: there is also a special Export command Export2 which enables you to export to a specific target file and format. When using Export2 you have to give the full file name (including path and filename extension).
Note carefully that the filename is not dynamically changeable when running the Macro, once set in the Export2 parameters, so you may wish to create several Macros the Export2 each targeting different file locations, names and filetype.
"C:\\Users\\<username>\\Desktop\\my file.flac" (this works)
Not: C:\\Users\\<username>\\Desktop\\my file.flac (the file name is not quoted)
Not: "my file.flac" (no path given)
Not: "C:\\Users\\<username>\\Desktop\\myfile" (no file extension)
The quote marks around the file pathing are supplied by Audacity once the Export2 command has been edited in setting up or editing the Macro
When entering the pathing data in the edit parameters dialog for the command you do not put the quote marks for example: C:\\Users\\<username>\\Desktop\\my file.flac
Deprecated Export commands
The following two commands are now deprecated and may well be removed in future versions of Audacity. They were part of "CleanSpeech" (which has long been removed from Audacity).
- The Export as MP3 56k before and Export as MP3 56k after commands can be used respectively to export "before" and "after" MP3 files at 56 kbps bit rate at any point in the Macro processing. This allows you to compare the result of one or more effects, or provide files for different purposes with and without a particular effect.
- The name of the MP3 exported by the "Export as MP3 56k before" command is prefixed by "MasterBefore_" followed by the date and time. The name of the MP3 exported by the "Export as MP3 56k after" command is prefixed by "MasterAfter_" followed by the date and time.
Comments in Macros
Comments be added to Macros to enable you to document what is happening in the Macro.
Use the "Comment" command in the Macros command to set and edit its parameters to type the text of your comment.

This smaller version is useful for presets. It stays open after applying a macro, so it is a palette of custom functions, and you can pick another and apply that.
