Something like this should be default in MacOS. I use blackhole daily in my audio production and sound design practices. If you use a modern audio interface you might have a loopback available there.

macOS 14.2 implemented something like this in Core Audio, but it is not user facing (and also documented extremely poorly). You can create a "Tap" that can capture audio from a particular application, or subset of applications, or an output device. This can then be added to a private or public Aggregate Device (depending on the Tap being private or public).

Sweet! Thanks for sharing, I will keep my eyes on this.

As a Linux user I'm lacking some context here. Does the default in macOS have too high latency? Or how is BlackHole different from it?

macOS doesn’t have a loopback device by default
