The unity project uses version 2022.1.0b9 so make sure you download the proper unity installation.
All unity versions can be found here: https://unity3d.com/get-unity/download/archive
Download and use unity hub to manage all of your unity installations/projects: https://unity3d.com/get-unity/download
In unity hub, add an existing project by clicking add and navigate to where you downloaded this repository. Make sure you're in the root directory where you can see the 'Assets' folder when you click open.
Unity has a useful tool called the point cache bake tool (Window>Visual Effects>Utilities>Point Cache Bake Tool) where you input a mesh and it exports a set of points that can be used by VFX graphs. This was used to create a point graph of a person which was imported into a custom VFX graph. Here's a tutorial explaining most of the process: https://www.youtube.com/watch?v=j1R1Uelroco&t=101s
Note: Point cache bake tool works best with meshes from .obj files. Problems were found using it with .fbx files.

Bias - the value threshold for when a beat will occur to music. Higher values are for stronger notes. Range is 0-100
Time Step - the amount of time required between two beats
Time to Beat - the amount of time it takes for an effect to trigger
Rest Smooth Time - the amount of time it takes to revert back to the original state defined by the restVector
For the beat and rest vectors, the xyz values correlate to the following VFX turbulence variables: (X: intensity, Y: drag, Z: frequency)
X/Intensity is the strength of force applied to the partice velocity
Y/Drag is the strength of directional forces applied to the particle velocity
Z/Frequency the period in which the noise is sampled
Beat Vector Upper Bound - The upper bound for range values that will be set once a beat occurs
Beat Vector Upper Bound - The lower bound for range values that will be set once a beat occurs
Rest Vector - The default values that the graph goes back to when there are no beats occuring
Random Range - Will activate functionality for the XYZ values to be randomly selected between a range of the beat vector and rest vector
Attraction Speed - How fast the particles conform to the sphere
Attraction Force - How strong the conforming force is
Stick Distance - How far away the particles will tend to stick
Stick Force - How strong the sticking force
These velocity curves apply different forces based on time passed. You can add infinite points on the graph
For the orb, there are 2 VFX graphs used so you can change all of the above values for both. They don't have to be the same and will probably look cooler with different values
Import an obj into the assets folder of the project, or select a preexisting one with the point cache bake tool
Here's how to open the point cache bake tool:
