Audio2Blender is an add-on that lets you sample any live audio source on your computer and send the data directly to Blender's Geometry Nodes in real time. It captures input from microphones or external sound devices and converts the sound into float values for driving procedural animations and simulations.

The tool features two primary sampling modes. Volume mode outputs a single float value based on audio loudness. FFT mode provides a series of values separated into frequency bands within a specified range, supporting both linear and logarithmic scaling. This enables precise control when creating sound-reactive visual setups.
