Works fine with YouTube. Simple but useful tool! Thanks again!!! ### 1/5 — For what ? *2026-09-23* Apple Music doesnt work. Youtube doesnt work. All Music Streaming Apps doesnt work. The next problem is, that porthole doesnt cut the system audio during capturing. original audio is hearable and the capture audio is hearable with delay together. i dont understand the application of porthole. **Developer response:** Hi! YouTube does work with Porthole. Apple Music, Netflix, and some other apps restrict audio capture during screen recording, including through Porthole. Feel free to email me at porthole@fer.as. I’d be happy to hear how you’d like to use Porthole and see how I can help. ## Frequently asked questions about Porthole Audio ### What can Porthole Audio do?
