I have made several interesting things:

• I have figured out how to use the models with onnx without tract (tract has streaming while onnx runtime doesn't)
• I have figured out how to run it with onnx on gpu on desktop and android
• I have developed efficient way to process frames + run DeepFilterNet in its own thread - to improve performance
• I have merged the 3 models into a single model - to improve performance
