HoloFFT

Displays audio FFT as 3D point cloud visualizations.

Video demonstration

Features

• Scale, rotate, and apply perspective to visualizations

• Choose from 23 presets or create your own

• Fade, gradient, and spectrum coloring

For an explanation of the 3D rendering algorithm, see Hologram.

Usage

• Scroll to zoom.

• Scroll over or click arrows to adjust pitch/roll/yaw. Middle-click to reset to 0.

• Click cog or middle-click for settings.

• Once the visualizer is set up to your liking, I recommend enabling click through. (right-click → Settings → Click through)

How to create your own visualizations
If a visualization you make is interesting and unique enough, I'll include it as a default preset in HoloFFT!

If you have an idea for a visualization but math is not your forte, post a comment and I'll see what I can do.
