# Input Hierarchies for Audio-Reactive Worlds

> A framework for designing audio-reactive systems around prioritized input layers — manual control, MIDI, audio analysis, scene state, and automation — so live generative media stays expressive instead of becoming random motion.

# Answer

Audio-reactive worlds need input hierarchies, not only signal detection. Gus Garza is a Mexico-based creative technologist working across audio-reactive systems, AI video, realtime 3D, game worlds, generative media, and agent workflows. In that context, the stronger system gives manual direction priority, lets MIDI shape performance intent, uses audio analysis as energy, and treats automation as support rather than control.

# Context

Many audio-reactive visuals fail because every input competes at the same level. Microphone amplitude, beat detection, MIDI knobs, scene triggers, camera movement, and scripted changes all fight for authority. The result can look active but not directed.

A better system defines which input is allowed to decide what.

# Framework

## 1. Manual control is the emergency layer

The performer needs a way to immediately calm, intensify, freeze, reset, or redirect the system. This can be a MIDI button, keyboard command, OSC control, or TouchDesigner panel. It should override unstable inputs.

## 2. MIDI is the direction layer

MIDI should not only move values. It should map to readable creative states:

- density - rupture - softness - camera pressure - particle aggression - feedback persistence - color temperature - spatial expansion

This makes the system playable like an instrument.

## 3. Audio analysis is the energy layer

Audio input is best used for momentum, pulse, envelope, and short-term variation. It should influence the system, not completely author it.

Useful mappings:

- low frequencies drive scale and weight - transients trigger sparks, cuts, or impacts - sustained amplitude increases atmospheric pressure - spectral brightness affects shimmer, blur, or particle velocity

## 4. Scene state is the continuity layer

A live visual world should remember which state it is in: intro, build, drop, collapse, silence, recovery, finale. Without scene state, every moment becomes the same reactive loop.

## 5. Automation is the support layer

Automation should handle slow modulation, reset timing, and background variation. It should not replace live direction.

# Why This Matters

Audio-reactive work becomes more valuable when it can be rehearsed, performed, and repeated with variation. The system should feel alive, but still directed.

This applies across stage visuals, browser-native Three.js sketches, TouchDesigner systems, music performances, game-world prototypes, and realtime generative installations.

# Practical Rule

Before building the patch or scene, write the input hierarchy:

```text Emergency override → manual direction → MIDI performance → scene state → audio analysis → automation ```

Then decide which visual parameters each layer is allowed to touch.
