INSTALLATION

Blender 4.2 and newer: Edit > Preferences > Get Extensions > Install from Disk, and pick the downloaded .zip. Enable it, then find the panel in the 3D viewport sidebar (press N).

QUICK START

1. Open the sidebar in the 3D Viewport (N) and click the Audio Trigger tab.
2. Click the clock icon to add a BPM input. It starts at 120 BPM with a metronome click.
3. Right-click any value, for example Scale, and choose Use in Audio Trigger. Press Space: it moves on the beat.
4. For music, click the speaker icon instead, pick your file and press Analyze Audio.
5. When it looks right, open Baking and press Bake All.

FEATURES

1RIGHT-CLICK ANY VALUE. IT MOVES TO THE MUSIC.

Right-click a property, choose Use in Audio Trigger, press Space. It pulses on the beat straight away, live in the viewport, before a single keyframe exists.

2ONE 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.

3WAVES, TIMED IN BEATS

Stagger 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.

4HEAR THE BAND. SEE THE HIT.

Filter the track down to the lows, mids or highs and listen to exactly what the detector hears. The waveform shows the threshold and every hit, so you tune by eye and ear, not by trial and error.

5A BEAT GRID, OR ANY AUDIO FILE

Work to a BPM grid with a metronome click before the music even exists, or load WAV, MP3, FLAC, OGG and more and let it find the hits.

6SHAPE HOW EACH HIT FEELS

Snappy or smooth pulses, hits that randomly skip for a looser feel, and quiet hits that move less than loud ones.

7BUILT FOR SCENES WITH DOZENS OF MAPPINGS

Group mappings so they share settings, select a range and change them all in one drag, search and rename like the Outliner, and jump between the list and the viewport.

8BAKES TO PLAIN KEYFRAMES

Bake to ordinary, sparse keyframes and the add-on is out of the picture: the file renders anywhere. The X beside Bake removes only what Audio Trigger wrote and puts the original value back.

9RHYTHM TOOLS

Drop timeline markers on every beat, or every half or quarter beat, and let Auto-Detect BPM read the tempo from the track.

GOOD TO KNOW

• It animates hits, not a continuous loudness curve. For spectrum bars or a smooth volume meter, use something else.
• Three fixed frequency bands, and stereo audio is mixed to mono.
• Bake before you render. Live Preview drives the viewport and pauses while a render runs.
• A very loud drop makes quieter parts of the track trigger less. A per-mapping threshold or an active frame range fixes it.
• The track always starts at frame 1, and shape keys can't be mapped yet.
