English | 简体中文
A guitar and bass amp simulator built in Rust. Runs standalone with JACK, or as a VST3/CLAP plugin in your DAW.
- Low-latency audio processing with configurable oversampling (1x–16x)
- 12 DSP stages: preamp (with 12AX7 triode clipper), compressor, tone stack, power amp, noise gate, level, multi-band saturator, delay, reverb, tremolo, 16-band graphic EQ, and NAM (Neural Amp Modeler) model loading (WaveNet + LSTM
.namfiles) - Per-stage bypass and stage reordering within the chain
- Impulse response cabinet simulation for both guitar and bass
- Saving and loading presets with keyboard hotkey switching
- Real-time recording capability
- Built-in tuner
- FFT-based pitch shifting for alternate tunings without retuning your instrument
- MIDI controller support
- VST3 and CLAP plugin builds for DAW use — see Plugin
- Tabbed GUI with minimap, collapsible stage cards, and input filter controls - built with Iced
- English and Simplified Chinese UI
- Linux with PipeWire (JACK support enabled)
- Rust toolchain: Install Rust
Note
This has been tested on a Raspberry Pi 4 and reasonably high end desktop PC. Your mileage may vary on other hardware.
You can download a tarball of a pre-built binary from the releases page.
sudo apt-get install libjack-jackd2-0
tar -xf rustortion-standalone-x86_64-unknown-linux-gnu.tar.xz
cd rustortion-standalone-x86_64-unknown-linux-gnu
./rustortionWith the rust toolchain installed, you can clone the repository and run the application:
sudo apt-get install libjack-jackd2-dev libasound2-dev pkg-config
cargo run --releaseTip
On some Linux machines with PipeWire, you may need to run JACK explicitly:
sudo apt-get install pipewire-jack
pw-jack cargo run --releaseRustortion also ships as an audio plugin in two formats: CLAP (Rustortion.clap) and
VST3 (Rustortion.vst3). Both are built from the same code and expose the same GUI as the
standalone app.
Bundles are published for three targets:
| Download | Platform | Status |
|---|---|---|
Rustortion-linux-x86_64.zip |
Linux x86_64 | Tested in a DAW |
Rustortion-linux-aarch64.zip |
Linux aarch64 (Raspberry Pi) | Builds in CI, not hand-tested |
Rustortion-windows-x86_64.zip |
Windows x86_64 | Builds in CI, not hand-tested |
Note
The aarch64 and Windows bundles are built natively in CI on every release, but have not been loaded in a DAW by hand. They should work; if one doesn't, please open an issue. There is no macOS build — it needs an Apple Developer ID for signing and notarization, without which a DAW will refuse to load the plugin.
Download the archive for your platform from the releases page and unpack both bundles into your plugin folders:
On Linux (substitute aarch64 for x86_64 on a Pi):
sudo apt-get install libjack-jackd2-0
unzip Rustortion-linux-x86_64.zip
mkdir -p ~/.clap ~/.vst3
cp -r Rustortion.clap ~/.clap/
cp -r Rustortion.vst3 ~/.vst3/~/.clap and ~/.vst3 are the standard per-user plugin directories on Linux; most hosts scan
them by default.
On Windows, unzip Rustortion-windows-x86_64.zip and copy Rustortion.clap into
%COMMONPROGRAMFILES%\CLAP and Rustortion.vst3 into %COMMONPROGRAMFILES%\VST3 (typically
C:\Program Files\Common Files\).
Rescan plugins in your DAW afterwards.
To build the plugin from source instead:
make plugin # builds target/bundled/Rustortion.{clap,vst3}
make plugin-install # copies them into ~/.clap and ~/.vst3This is an experimental project. Feel free to open issues or submit pull requests.
