Audio Plugin Creation and Hosting

VST and AU generation, testing, validation, and hosting

Audio Toolbox™ enables you to debug and validate your MATLAB^® audio plugins using a series of static and dynamic tests. You can then generate VST or AU audio plugins and deploy to your preferred digital audio workstation (DAW). You can also host VST, VST3, and AU plugins in MATLAB by using the loadAudioPlugin function. Use the Audio Test Bench app to debug and tune your audio plugins in MATLAB.

Featured Examples

Ambisonic Plugin Generation

This examples shows how to create ambisonic plugins using MATLAB® higher order ambisonic (HOA) demo functions. Ambisonics is a spatial audio technique which represents a three-dimensional sound field using spherical harmonics. This example contains an encoder plugin, a function to generate custom encoder plugins, a decoder plugin, and a function to generate custom decoder plugins. The customization of plugin generation enables a user to specify various ambisonic orders and various device lists for a given ambisonic configuration.

Communicate Between a DAW and MATLAB Using UDP

Communicate between a digital audio workstation (DAW) and MATLAB® using the user datagram protocol (UDP). The information shared between the DAW and MATLAB can used to perform visualization in real time in MATLAB on parameters that are being changed in the DAW.
