Your music drives your scene. Automatically.

AudioReact turns any audio track into clean, frame-perfect keyframes inside Blender. Load a song, pick a genre preset, hit Bake: lights pulse on the kick, shaders flare on the snare, geometry moves with the bass.

No manual keyframing. No real-time hacks. Just baked animation you can render with confidence.

HOW IT WORKS

1. Load your audio: MP3, WAV, FLAC and most formats, decoded through FFmpeg (one-click install built in).
2. Pick a preset: choose a genre and an element (kick, snare, sub bass, hi-hat…). AudioReact targets the right frequency band for you.
3. Bake: STFT analysis writes F-curve keyframes directly onto your targets, ready to render in Cycles or Eevee.

DRIVE ANY PROPERTY

One track can drive as many targets as you need:

• Shader, World & Compositor nodes: link any Value node in one click with "Capture Active Node"
• Geometry Nodes: modifier inputs
• Lights: power in Watts, with min/max range
• Object transforms: scale, location, rotation, including accumulated rotation (continuous spin that speeds up with the music)
• Modifier properties: any animatable value

GENRE PRESETS

Frequency profiles tuned per genre and per element. Pick one and get instant results, then fine-tune.

• Genres: Drum & Bass, Dubstep, Techno, House, Trance, Wideband
• Elements: Sub Bass, Kick, Snare, Hi-Hat, Low End, Mid, Pad, Atmos, Highs, Air, Full
• Auto Reco: applies recommended settings for the selected preset
• Save your own settings as reusable Profiles

SHAPE EVERY HIT

• Attack / release follower, in milliseconds
• Transfer curves: Linear, S-curve, Log, Exp
• Per-band weighting: Flat, Triangular, Gaussian
• Gain, contrast, gain ramp over time, median and box smoothing
• Live envelope preview with Low / Medium / High resolution

COUNTER MODE

Instead of a 0→1 pulse, the value steps +1 on every detected hit: 1, 2, 3, 4… Perfect for switching shots, cycling colors, stepping through sequences or rotating elements beat by beat.

BUILT FOR REAL PROJECTS

• Multi-track: stack as many tracks as you need, each with its own preset and targets
• Per-track bake ranges
• BPM detection
• Keyframe density: per frame (lightweight) or per audio hop (ultra smooth)
• STFT quality: Fast / Balanced / Precise

WHO IT'S FOR

Motion designers, VJs, music video and visualizer creators, and anyone making content for artists and labels. If sound is part of your work, AudioReact belongs in your toolkit.

Made by ITUR (@itur.motion), a motion designer working in the hard techno and Dubstep scene. His visuals have been played at Excision's show and Lost Lands festival.

FAQ

Is it real-time?
No. AudioReact bakes keyframes, so your render always matches the audio exactly, with no live analysis and no surprises at render time.

Which audio formats are supported?
Anything FFmpeg can decode: MP3, WAV, FLAC, OGG and more. FFmpeg installs in one click from the add-on.

Cycles or Eevee?
Both. The result is standard keyframes, so it works with any render engine.
