Design applications in MATLAB and then perform standalone deployment onto Arduino hardware using MATLAB Function blocks in Simulink. You can tune your algorithm for a better performance and monitor signals from the hardware in real-time using External Mode. In this example, an audio processing application has been developed, implementing audio effects such as Echo, Reverberation and Pitch-Shifting.
