Class NoiseSettings
This is an asset that defines a noise profile. A noise profile is the shape of the noise signal as a function of time. You can build arbitrarily complex shapes by combining different base perlin noise frequencies at different amplitudes.
The frequencies and amplitudes should be chosen with care, to ensure an interesting noise quality that is not obviously repetitive.
As a mathematical side-note, any arbitrary periodic curve can be broken down into a series of fixed-amplitude sine-waves added together. This is called fourier decomposition, and is the basis of much signal processing. It doesn't really have much to do with this asset, but it's super interesting!
