Virtual Audio Device/Card/Adapter

Looking to create a simplified version of Virtual Audio Cable for a specific use-case. But I can't figure out how to create a virtual audio device in Windows, with or without Rust.

Anyone know a way to do so with Rust (existing crate for it preferred)? Currently figuring out cpal, so would prefer if it is compatible with it (I should be able to write to a virtual input with it anyway, since it should just be detected as an audio device).

Thanks for the help.
