Some setups get part of the way. On Windows, some applications can record the system mix by switching their own audio device into a loopback mode. That works inside that one application, on that one platform, and it repoints your entire audio device while you use it, so your interface and your monitoring change along with it. It also connects outputs back to inputs, which is easy to get wrong and loud when you do.
macOS has no built-in equivalent today. The next major release adds system audio to screen recordings, which gives you a video file, not a track in your session and not an input device that Zoom or OBS can select.
AudioRoute is about where the audio lands. One install puts it on a track in any DAW, exposes it as a recording device any application can choose, or writes a WAV on a keystroke, on macOS and Windows alike. And it taps the signal in parallel, so your output device, your interface and your monitoring latency are exactly what they were before you installed it.
