Achat
Audio Trigger makes anything in Blender move to the music. Right-click a value (scale, a modifier, a shader, a light) and it pulses on the beat, live, before a single keyframe exists. When it looks right, bake it to plain keyframes.

How it works
Three steps, in the Audio Trigger tab of the 3D Viewport sidebar.
 |
Step 1 Right-click any valueRight-click a property and choose Use in Audio Trigger. Press play and it pulses on the beat straight away, live in the viewport. |
 |
Step 2 Hear what it hearsLoad a track and pick the band: lows for the kick, mids for the snare, highs for the hats. Filter Playback plays only that band, and the waveform shows the threshold and every hit. |
 |
Step 3 Bake to plain keyframesBake All writes ordinary, sparse keyframes, so the file renders anywhere. The X beside Bake removes only what Audio Trigger wrote and puts the original value back. |
Built for a whole scene
One track drives everything, and every mapping keeps its own settings.
 |
One track. Every object reacts differently.The kick scales one object, the snare flashes a light, the hats flicker a shader, and a fourth element only moves in the chorus. All from one audio file and one input.
|
Waves, timed in beatsStagger a row of objects into a wave with one click, timed in beats rather than frames. Change the step and run it again; nothing to re-key.
|
 |
 |
Shape how each hit feelsSnappy or smooth pulses, hits that randomly skip for a looser feel, and quiet hits that move less than loud ones.
|
Dozens of mappings, one dragGroup mappings so they share settings, select a range and change them all at once, search and rename like the Outliner.

Good to know
No track yet?A BPM grid with a metronome click drives everything before the music exists: 11 divisions from 1/32 to 32 beats. |
Rhythm toolsTimeline markers on every beat, half or quarter beat, and Auto-Detect BPM reads the tempo from the track. |
Audio Trigger LiteThe BPM grid edition, a version on this same page. The full version adds real tracks. |
Audio Trigger or stock Blender
Blender can already turn sound into a curve. Audio Trigger is for everything after that.
| Task | Stock Blender | With Audio Trigger |
|---|---|---|
| Make a value follow the music | Keyframe the channel, Sound to Samples, then Samples to Keys | Right-click, Use in Audio Trigger |
| Decide what counts as a hit | Bake, look, undo, try again | Hear the band, see the threshold while you tune |
| Twenty objects, each different | A separate bake for every channel | One track, settings per mapping |
| A wave across a row | Offset keys by hand in the Dope Sheet | Spread Offsets, timed in beats |
| Animate before the music exists | Beat maths and hand-placed keys | A BPM grid with a metronome click |
| What you end up with | Sampled curves | Plain, sparse keyframes, removed in one click |
| A smooth loudness curve or spectrum bars | Sound to Samples does this | Not this: Audio Trigger animates hits |
