## noiseless-lv2 - LV2 wrapper for https://github.com/jneem/nnnoiseless
This plugin lets you run nnnoiseless neural noise canceller as an LV2 plugin in Carla or any other host.
### Features:
* Real-time denoising of your mic input (or any audio stream).
* Uses the same model as VRChat's built in voice denoiser.
* Works on Linux (x86_64), Windows and MacOS.
### Installation:
**Requirements:**
Rust + cargo
LV2 headers (on Debian-based distros: sudo apt install lv2-dev)
```
git clone https://github.com/YOURNAME/noiseless-lv2.git && cd noiseless-lv2/
cargo build --release
mkdir -pv ~/.lv2/noiseless-lv2.lv2/
cp target/release/libnoiseless_lv2.so ~/.lv2/noiseless-lv2.lv2/
cp manifest.ttl denoise.ttl ~/.lv2/noiseless-lv2.lv2/
```
### Usage:
Open up Carla or another LV2 host and add the "nnnoiseless Denoise" plugin from the LV2 list.
Route your mic or noisy signal through it!
**NOTE:** The plugin expects a sample rate of **48kHz**.
If your system uses a different sample rate you'll need to resample before passing audio to the plugin.
#### Example Carla Patchbay Setup:
```
Mic -> [Noiseless-LV2] -> Output / Discord / OBS etc...
```
Enjoy!
```
