[Jack-Devel] virtual Microphone?

Hello everyone, I was wondering if with jack I could create a virtual microphone to use, I have a hosted server which obviously doesnt have sound card, and I would like to stream sound via network to the server and process it using some python packages, for that my script fails because it looks for the sound card, and I would like to setup a virtual microphone to feed my application, is this possible? Greetings
