How to access microphone stream in Mac?

Hi, I am trying to port my Win Forms app to Mac and have a question regarding microphone access.

In my WinForms app, I use NAudio to capture the microphone stream and run through some speech recognition in realtime.

But unfortunately I am unable to import the NAudio Nuget in my Xamarin.Mac app. I believe it is incompatible.

So my question is, how can I go around accessing the microphone stream on a Mac? What APIs exists. My research mostly resulted in iOS or Android related APIs but not much on Mac.

Any pointers will be greatly appreciated.
