1, audio spectrum effect: link to audio layer, path circular mask, display analog spectral lines, other maximum height colors, etc. Just try to adjust it. Finally, add a luminous effect.

2. Box: Specific, layer emitter, create a ring emitter map less than 1 The map of the particle is a rectangle: the stroke is 100% opacity, and the fill should be 30% opacity. Adjust other parameters properly and finally add a luminous effect.

3. Dot-shaped light bars and particles should be thin by default. Change the number of particles to fewer points, add radial blur, and change it to scale. Note that the center point is in the center of 1. You should be able to draw a band of light, and then add some light appropriately.
