The wire - Frame by frame Instancer and scaler in Geometry Nodes 3D model

THIS IS A NODE SETUP WITH MATERIAL EXAMPLES FOR INSTANCING OBJECTS EVERY FRAME ON A CURVE AND SCALE THEM BY THE CURRENT AUDIO VALUE OF A CHOSEN SONG.

The method and the node setup is as simple as possible, for easy readibility and reuse and utilizes only Geometry Nodes. The nodes are labeled for further clarification.

Video demo here, here and here !

The interpolation of the scaling, the audio and the object to instance and its scale is completely customizable.

An other version with similar effect, but scaling the curve object itself can be found under the name Curve Scaler.

NOTE

-(Since it is a concept demonstration, it is kept as simple as possible.) The GeoNodes trees are kept clean, the nodes are not contracted into node groups for easier readability and have detailed explanations. You can embellish, refine as you wish.

-(The files are working in Blender 3.6X AND ABOVE utilising the Simulation Zone feature)
