Sound to Keyframes

There are many tutorials on the internet on how to “bake sound to f-curves”, “sound to keyframes”, “bake sound to effects”. Here is a very quick run-down on how to test/start with this with BlenderDMX addon:

  1. Create a basic scene:

    • Add single fixture
    • Add haze for volumetric beams
    • Clear the fixture and set intensity and color

  4. Bake sound to F-curves:

    • Open Graph editor
    • Select desired item in the listing of recorded elements, for example Spot size (Zoom)
    • Select Channel - Sound to Samples
    • This adds the audio waveform to the timeline
    • Now when you play the timeline, the zoom will react
