This project may ask for access to your Microphone and Camera if you have not run projects that use these before. (This project does not use the Camera). The Sound Visualizer needs access as it reacts to sound. * If you hum, the sound vibrations make the visualizer very active! If you decline access (or your device does not have a microphone) then default sound levels will be used.
This project is a hybrid of two of my earlier projects: Spiky Dodecahedron: https://scratch.mit.edu/projects/219401501/ and Sound Visualizer: https://scratch.mit.edu/projects/179884967/ The Sound Visualizer reacts to the tune played and any sounds that you make, especially humming which makes good sound waves! If you want the project to react only to your voice or music, just turn the speakers off on your PC or device.
