ComfyUI-AudioReactive

Draw a waveform as an IMAGE

Load a file into a SIGNAL

Make everything non-negative before it feeds an envelope

Bandpass — a Butterworth filter that's not wired up yet (read this first)

Clamp — a ceiling for your signal that never got connected (stub warning)

Harmonic — peel the melodic layer off your audio with HPSS

Modulo — thin out a beat train by taking every kth peak (and why it's a stub)

Normalize — the one node that makes every other operator's output usable

Novelty — an onset-strength curve that spikes exactly when the beat hits

Percussive — grab the drums and transients with HPSS

Pow — arbitrary exponent shaping, and the builtin-`pow` collision that left it a stub

The cheapest dynamic-range trick in the pack

Predominant_Pulse — the tempo-locked curve that tracks the beat, not the hits

Quantize — bucket a signal into k discrete levels with k-means (stub warning)

RMS — the energy envelope that's doing half the work in audio-reactive work

Smoosh — gentle compression that pulls quiet passages up into the mix

Smooth — a Hann-window smoother that should be the pack's most-used node (if it worked)

Sqrt (Audio Op) — the name is a lie, it actually computes y⁻²

Stretch — punch up a driver curve with normalize → square → normalize

Sustain — an asymmetric 'hold then decay' envelope that's still a stub
