Audio2Blender Extension + SP1

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.

Note:

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.

FAQ

Can I render my RT visuals and stuff?

No you can't. What you see in my video are playback and render in the Blender viewport. I record my screen with OBS. The system I recorded on is a Macbook M1 Pro 16GB.

How can I separate the bass signal from the drums?

You can’t — the frequency ranges of different instruments often overlap. Audio2Blender doesn’t isolate or separate instruments; it only analyzes the combined audio signal in real time based on frequency and amplitude.

Can I record the audio signal to render it in a video?

No — at least as far as I know. This software is designed for real-time interaction, not for recording or exporting audio.

Can I sample multiple channels from my audio interface?

No — Audio2Blender can only sample one input channel at a time.

Jellyfish, Sound Reactive Game and Ferrofluid are included?

They are not included.
