Audio Effects (Echo, Reverb, and Pitch-Shift) with Arduino

An audio processing application designed in MATLAB and deployed to Arduino using MATLAB Function blocks in Simulink.

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:
