In this Blender 2.5 video tutorial, we will be taking a look at how to use sound to drive an object’s scale.
We will be building a ‘field’ of cubes, each of which will pulse along to certain frequencies of a song.
What is covered in this tutorial:
- Baking sound to F-curves.
- Programatically creating an N-by-M matrix (field/ grid)
- Setting a keyframe and baking F-curves from Python
- Finding out which frequencies to use using Audacity
Note: In recent SVN versions the API has been updated. If you’re using one of these later versions please be sure to replace “bpy.ops.object.scale_apply()” with “bpy.ops.object.transform_apply(scale=True) “
