Audio2Blender Extension samples audio sources in Real Time and feeds Geometry Nodes with usable values — all inside Blender! This means you can create any kind of sound-reactive content: real-time visuals, games, art installations, and more.

You can sample a microphone or any external sound device and obtain float values for animation and simulation in two modes: Volume or FFT (Linear + Logarithmic).

In Volume mode, you get a single float value.

In FFT mode, you get a series of values based on the number of bands within a specified frequency range.

SP1 (Starter Pack1) is an assets pack that simplify the process of sampling, triggering, and animating real-time audio values in Geometry Nodes with Audio2Blender Extension.

Audio2Blender is designed for real-time interaction and does not include a built-in way to record data values.
You can't separate the audio into individual instrument stems.

Jellyfish, Sound Reactive Bird and Ferrofluid projects are not included.
