Pipewire NVIDIA Denoiser

This is a Pipewire Noise Suppression DSP filter using NVIDIA AudioEffects API, this is just a test and not a finished product and will only work with 48kHz audio and it's dynamically linked against libraries in the vendor folder because I'm lazy.

Building

if you want to build it you need to add cuda11.3, nvafx and models and then run make

vendor
├── cuda
│  └── lib
├── models
│  └── sm_86
└── nvafx
   ├── include
   └── lib

Running

Execute the binary with one argument which is the path to a model then you can route the audio through the NVIDIA Denoiser filter in Helvum or some other tool. If possible, configure pipewire to not use power of two quantums clock.power-of-two-quantum = false and set your quantum size to 512, hopefully pipewire will automatically set set the quantum to 480 and the denoiser wont use xrun.
