Full disclosure up front: I'm building SyntaxCue, a desktop app that listens to a live call and helps you think through the answer in real time. None of that matters for this post — this is the engineering diary from getting system-audio capture working the same way on macOS and Windows. "System audio" sounds like it should be one API. It isn't. macOS gives you the CoreAudio Process Tap (Swift-only, no Rust bindings), and Windows gives you WASAPI opened in a mode nobody advertises as "the loopb
