Loopback
Rogue Amoeba's paid virtual audio routing app. Powerful, but for meeting transcription it is overkill compared to ScreenCaptureKit.
Loopback is a commercial Mac app from Rogue Amoeba (the makers of Audio Hijack) that lets you compose virtual audio devices out of arbitrary input and output sources. It is the gold standard if you need to mix podcast guests, system audio, and a hardware mic into one stream that OBS can record.
For the narrower job of 'record both sides of a Zoom call', Loopback is more than the workflow needs. ScreenCaptureKit + Core Audio process tap covers the same use case with one Screen Recording permission and no additional purchase. Mac Note Taker uses the native path.
