How to set up my own onnx model on jetson nano

Hey there,
I’m really new to the jetson nano and neural networks. So I created a neural network with matlab and saved it as an onnx model. Now I want to open an audio file on the jetson nano which then gets analysed by the neural network.
What would be the most common way to set this up properly? I only found information on how to set up pretrained onnx models.

I’m happy about any information. Thanks a lot in advance
