Audio Sphere is a website that is made to visualize music you upload to it.
The sound is visualized by moving small spheres that are arranged in a way they make a bigger sphere and then moving those small spheres.
It works by doing FFT (Fast Fourier Transform) on the sound live as it is playing, I take the output of FFT and move each small sphere by the value of equivalent element of the FFT output.
The code is hosted on Netflify - Audiosphere
