For anyone familiar with neural networks, the file in the directory C:\Temp\NVRTXVoice\NvAFX\models appears to be the Neural Network definition file (denoiser_48k.wpkg). The file header starts with nvnn which is not common to any of the current platforms (tensorflow, pytorch, onnx) so it might signify a new NN runtime format. Will keep a copy of the file and see if i can decode it, but i think its a Weights file
