Include an Audio Plugin in Simulink

This example shows how to use the Audio Plugin block to include an audio plugin in a Simulink^® model.

Generate Block from Plugin

Place the Audio Plugin block in a Simulink model. You can find the block in the Audio Toolbox / User-Defined Functions library.

Double-click the block to open the dialog box. In the Audio plugin field, enter the plugin audiopluginexample.Echo. To inspect the source code for this plugin, enter edit audiopluginexample.Echo in the command line. Optionally, specify the name and location of the generated System object™ class file using the Generated file name field.

Click OK to generate a block with the same functionality as the plugin. This also generates the System object class file and places it in the current directory by default. The file must be on the MATLAB^® path for the generated block to work.

Double-clicking the new block opens the parameter dialog box, where you can view and edit the plugin parameters. You can also choose to specify the tunable parameters through additional input ports on the block.

Use Generated Audio Plugin Block in Model

This example uses:

Open Model

Use the plugin in a model to process an audio signal and listen to the results. Add a Slider (Simulink) block to the model to tune the gain parameter of the plugin during simulation.
