Smoothing, easing, and why your visuals strobe

The most common failure mode in reactive visuals is not bad math. It is using unstable input directly.

The short version

• Smooth inputs before you threshold them.
• Ease outputs when you want style, not when you need stability.
• Keep one source of truth per signal so you do not smooth the same thing twice.

float expGlide(float current, float target, float k) {
    return mix(current, target, 1.0 - exp(-k));
}
