This is the answer. You can play back the track on headphone and record another track on top. It even adjusts the input delay by pinging the mic through the headphones. Nifty stuff. Great for laying out ideas. Not professional by any means.
Probably USB. Since phones have a USB input, they can take things like USB mic interfaces. Get a 4-input interface, and there ya go.
Depending on the app’s permissions, it may even be able to take inputs from other apps, like Discord for call audio, or whatever app you’re streaming your music on.
Curious, how do you have four discrete inputs?
Looks like 4 separate recordings over a single channel input
