Stream Final Cut Pro to your iPhone
Final Cut Pro applies effects to clips, and it has no master bus to put a plugin on. The simplest way to hear a whole timeline on your iPhone is the free MixOutpost Mac app, which shares everything your Mac plays.
Why the Mac app, not the plugin
MixOutpost's plugin belongs at the end of a master output, and Final Cut Pro doesn't have one: audio effects go on clips (or on a compound clip of the whole timeline, which gets awkward fast). The Mac app sidesteps that by capturing what the Mac plays.
Set it up
- 01
Install the Mac app
Run the free MixOutpost installer and choose the app.
- 02
Share Mac audio

- 03
Start Sharing and pair
Click Start Sharing and Pair phone…, then scan the QR code with the MixOutpost iPhone app.
- 04
Play the timeline, tap Listen
Play in Final Cut and tap Listen on the phone.
Picture and phone aren't in sync
The phone plays about 60 to 200 ms behind your Mac's speakers, depending on the buffer and the Wi-Fi. That's fine for checking a mix, levels and loudness, but you'll notice it if you watch the picture on the Mac while listening for lip sync on the phone. Judge sync on your main monitors, and use the phone for translation and loudness.
What you can check from the phone
The same checks as in any host: mono and side-only listening, loudness with integrated LUFS and true peak, delivery targets like EBU R128, ATSC A/85 and Netflix, a diagnostic EQ, and recording to the phone. Up to eight phones can listen at once, so a director or client can hear it too (multiple listeners).
Status
Final Cut Pro: use the Mac app, which works today and is verified on real hardware for sharing Mac audio. MixOutpost runs on macOS, with the iPhone app on the App Store.
Questions
Is there a MixOutpost plugin for Final Cut Pro?
Final Cut loads Audio Units, but only on clips, roles inside compound clips and similar; there's no master output to insert a plugin on. Use the MixOutpost Mac app to share the whole timeline.
How do I hear Final Cut on my iPhone?
Install the MixOutpost Mac app, choose Mac audio (all apps), click Start Sharing and pair your phone. Everything the Mac plays, Final Cut included, comes through lossless and encrypted.
Do I need a loopback driver?
No. The Mac app uses a macOS system audio tap (macOS 14.2 or later), so there's nothing to install or route.
Will the phone be in sync with the picture?
No. The phone plays about 60 to 200 ms behind the Mac. Use it for translation and loudness, and judge lip sync on your main monitors.
Will other sounds come through too?
Yes. The Mac app shares everything the Mac plays, so silence notifications and other apps while you listen.
