Simulation, Tuning, and Visualization

Real-time prototyping and tuning, MIDI, audio test bench

Audio Toolbox™ enables real-time prototyping and tuning using MIDI devices and the Audio Test Bench. Modularize your algorithm as an audio plugin for code reuse and to access prototyping and testing tools. See Audio Plugins in MATLAB for more information.

Use the configureMIDI user interface to quickly synchronize an audio plugin with a MIDI device. Follow the Audio Test Bench Walkthrough to learn about the all-in-one graphical debugging and testing suite.
