Many-to-one buses vs visual graphs
- BlackHole: combine aggregate devices in Audio MIDI Setup — powerful, slightly more homework.
- Loopback: drag cables between nodes — faster onboarding for occasional volunteers.
Lock 48 kHz everywhere when WebRTC is downstream
Mismatched 44.1 vs 48 kHz invites hidden resampling — tighten CoreAudio, DAW project rate, and OBS before you blame the network.

Can I use both on one machine?
Possible but confusing — standardize on one virtual device per show to limit feedback loops.
Does macOS Ventura break drivers?
Check current release notes before tour season; keep a tested OS image.
What about Soundflower successors?
BlackHole is the common modern replacement path for many teams.
Will this fix Zoom-quality audio by itself?
Routing is half the battle — you still need gain staging and a WebRTC-first destination.
