Third-party licences

Last updated: 21 October 2026

In short — Jamodio's Noise Filter (the one that strips your instrument out of your talkback mic and closes the mic when you are not speaking) is built on two open-source components. They run entirely on your own computer: your voice is never sent to an analysis server, and the feature costs nothing.

1. Noise Filter components

DeepFilterNet — denoising

Separates the voice from everything else the mic picks up. DeepFilterNet, copyright © Hendrik Schröter and contributors. Distributed under your choice of MIT or Apache-2.0; the model weights ship under the same licence and were trained on the DNS-Challenge corpus.

Silero VAD — speech detection

tract — inference engine

Both models run on tract (Sonos), an ONNX engine written in Rust, under MIT or Apache-2.0. No extra native dependency is installed on your machine.

2. Yes, this is artificial intelligence

These are pre-trained neural networks. Three things worth stating plainly:

they run on your machine, never in the cloud;
your voice trains nobody — the models are frozen, shipped as they are;
they are free and will stay so: no third-party subscription is involved.

3. Licence texts

The full licence texts ship with the software, as those licences require: open the Audio Engine window and click “Licences”. The Apache-2.0 text is also available on apache.org.

4. ASIO software development kit (Steinberg)

On Windows, the Audio Engine talks to your audio interface through its ASIO driver, using the ASIO software development kit by Steinberg Media Technologies GmbH (version 2.3), under Steinberg's proprietary licence. The kit itself is not redistributed.

ASIO is a trademark of Steinberg Media Technologies GmbH, registered in Europe and other countries.
