generateAudioPlugin

Generate audio plugin from MATLAB class

Syntax

generateAudioPlugin className

generateAudioPlugin options className

Description

generateAudioPlugin className generates a VST 2 audio plugin from a MATLAB^® class specified by className. See Supported Compilers for a list of compilers supported by generateAudioPlugin.

generateAudioPlugin options className specifies a nondefault plugin type, output folder, file name, or file type. You can use the -juceproject option to create a zip file containing generated C/C++ code and a JUCER project. Options can be specified in any grouping, and in any order.

Examples

Generate Audio Plugin

generateAudioPlugin audiopluginexample.Echo

.......

A VST 2 plugin with file name Echo is saved to your current folder. The extension of your plugin depends on your operating system.

Specify Output Folder for Generated Plugin

mkdir(fullfile(pwd,'myPluginFolder'))
generateAudioPlugin -outdir myPluginFolder audiopluginexample.Echo

.......

A VST 2 plugin with file name Echo is saved to your specified folder, myPluginFolder. The extension of your plugin depends on your operating system.

Specify File Name of Generated Plugin

generateAudioPlugin -output awesomeEffect audiopluginexample.Echo

.......

A VST 2 plugin with file name awesomeEffect is saved to your current folder. The extension of your plugin depends on your operating system.

Specify Output Folder and File Name of Generated Plugin

mkdir(fullfile(pwd,'myPluginFolder'))
generateAudioPlugin -output coolEffect -outdir myPluginFolder audiopluginexample.Echo

.......

A VST 2 plugin with file name coolEffect is saved to your specified folder, myPluginFolder. The extension of your plugin depends on your operating system.

Generate win32 Plugin from win64 System

generateAudioPlugin -win32 audiopluginexample.Echo

.......

A 32-bit VST 2 plugin with file name Echo.dll is saved to your current folder.

Generate JUCE-Compatible Zip File

generateAudioPlugin -juceproject audiopluginexample.Echo

A zip file containing generated C/C++ code and a JUCER project file suitable for use with JUCE 5.3.2 to 6.0.8 is saved to your current folder.

Generate Standalone Executable

To generate a binary standalone executable, use the -exe option. The following command saves Echo.exe to your current folder.

generateAudioPlugin -exe audiopluginexample.Echo

.......

When you execute the generated code, the UI you defined in your audio plugin opens.

eval('!Echo.exe')

The standalone executable enables you to:

• Configure audio input and output from the plugin. Synchronizing parameters with MIDI devices is not currently supported.

• Save and load states.

• Reset states to default values.

Input Arguments

options — Options to specify output folder, plugin name, and file type

-au | -vst | -exe | -juceproject | -win32 | -output fileName | -outdir folder

Options can be specified in any grouping, and in any order.

Option	Description
-au	Generates an Audio Unit (AU) v2 audio plugin binary. This syntax is only valid on macOS.
-vst	Generates a VST 2 audio plugin binary. By default, generateAudioPlugin generates a VST 2 plugin.
-exe	Generates a standalone executable for your audio plugin. When you evaluate the generated code, the UI you defined in your audio plugin opens. You can control the input to your plugin and the output from your plugin using Options.
-juceproject	Creates a zip file containing generated C/C++ code and a JUCER project file suitable for use with JUCE 5.3.2 to 6.0.8. You can use the generated zip file to modify the generated plugin or compile it to a format other than VST 2.4. This option requires a MATLAB Coder™ license. To use the generated files with JUCE, you must obtain your own appropriately licensed copy of JUCE.
-win32	Creates a 32-bit audio plugin. Valid only on win64. This option does not support the coder.DeepLearningConfig('mkldnn') deep learning library configuration, the 'Intel AVX (Windows)' code replacement library, or the 'DSP Intel AVX2-FMA (Windows)' code replacement library.
-output fileName	Specifies the file name of the generated plugin or zip file. The appropriate extension is appended to the fileName based on the platform on which the plugin or zip file is generated. By default, the plugin or zip file is named after the class.
-outdir folder	Generates a plugin or zip file to a specific folder. By default, the generated plugin is placed in the current folder. If folder is not in the current folder, specify the exact path.
-audioconfig cfg	Generates a plugin that uses a deep learning network or a code replacement library. See audioPluginConfig for more details.

Only the -juceproject option is supported in MATLAB Online.

className — Name of plugin class to generate

plugin class

Name of the plugin class to generate. The plugin class must be on the MATLAB path. It must derive from either the audioPlugin class or the audioPluginSource class.

You can specify the plugin class to generate by specifying its class name or file name. For example, the following syntaxes perform equivalent operations:

• generateAudioPlugin myPlugin

• generateAudioPlugin myPlugin.m

If you want to specify the plugin class by file name, and your plugin class is inside a package, you must specify the package as a file path. For example, the following syntaxes perform equivalent operations:

• generateAudioPlugin myPluginPackage.myPlugin

• generateAudioPlugin +myPluginPackage/myPlugin.m

Limitations

Build problems can occur when using folder names with spaces. For more information, see Build Process Support for Folder Names (Simulink Coder) and Why is the build process failing for a shipped model in Simulink or for a model run in Accelerator mode?.
