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.

Here is a link to the video describing the Audio processing application:

Dear Meeshawn Marathe,

excellent demo for those who are working on Arduino+Simulink.

Is it possible to record audio on board (via attaching microphone) and then process it ?
kindly suggest implementation required on simulink.

it would be great help for application i am working on
