Hey, Is there anyway I can input my audio signal from my audio interface?

Hi, I’m really interested in this new Audio Capture plugin, I’ve been able to use the envelope value in my project to change some parameters, but I’d like to be able to choose the audio source, and possibly use several audio sources at once. I dont really understand how something like the “enumerate audio capture” node could be used for this? I’m just a beginner in UE4, so I dont really understand how you implemented the RTAudio Class, and what it’s used for. Can you help me?
