Hi, thanks for your interest! I'm still working on this project, though time between updates is long since the next update is ambitious and I've been busy.
Indeed the sound input options right now are only with microphone, or by directly playing audio files (wav, mp3, ogg). I don't think there's a straightforward way to get system audio input into Unity. However I know people have done it, so I can look into it... If I manage, it can be part of one of the next updates.
