Concentric

Overview

Concentric is a matrix effect that creates expanding and contracting rings from the center of the matrix.

It is audio reactive, using a selectable audio band-pass filter to control the speed of the rings’ motion.

Here’s an example with a 64x64 matrix & an 256x256 matrix:



Presets

  • RESET — Rainbow gradient; rings expand at a moderate speed.

  • OCEAN IMPLOSION — Blue-green gradient; rings contract.

  • FIRE EXPLOSION — Red-orange gradient; rings expand rapidly.

  • RAINBOW EXPLOSION — Fast rainbow gradient; rings expand rapidly.

Settings

The Concentric effect includes a few controls:

Concentric settings

  • Rotate — Rotates the effect by 90° for every unit.

  • Brightness — Self-explanatory.

Concentric effect specific settings:

  • Gradient — Gradient used for rings.

  • Frequency Range — Selects which audio band-pass filter controls the speed of the rings’ motion.

  • Invert — If enabled, makes rings contract instead of expand.

  • Speed Multiplier — Factor by which the power of the frequency band is multiplied. (Higher = faster.)

  • Gradient Scale — Scales the gradient across the matrix. (Higher, less repetitions.)

  • Stretch Height — Stretches the rings vertically. Useful for non-square matrices or not circular renders. (Can also be width with a rotation.)

  • Center Smoothing — Blurs the center of the rings to reduce harsh color changes. (Higher = blurrier.)

  • Idle speed — Minimum speed at any time. Useful to have a not-static effect during music changes or when no movement occurs in the specified frequency range. (Higher = faster.)
