Stream Pro Tools to your iPhone

Where the Pro Tools plugin stands

Pro Tools on the Mac loads AAX plugins only, not Audio Units or VST3. MixOutpost's first release is AU and VST3, which covers most other Mac DAWs. The AAX version is compiled from the same code, but Pro Tools only loads AAX plugins that have been signed through PACE, and ours hasn't been signed yet. So it's not in the installer, and we won't claim it works in Pro Tools until we've tested it there.

When it ships, the AAX plugin will work the way it does in Logic Pro: an insert at the end of your main output that sends only that signal, with offline bounces skipped.

Today: use the MixOutpost Mac app

You don't have to wait. The free MixOutpost Mac app captures everything your Mac plays through a macOS system audio tap and sends it to your iPhone. There's no loopback driver to install and no virtual device to route through. Details are on Mac audio to iPhone.

1. 01

   Install the Mac app

   Run the free MixOutpost installer and choose the app. It's signed and notarized, and it runs on Apple Silicon and Intel Macs.

2. 02

   Share Mac audio

   In the app, choose Mac audio (all apps) as the source rather than an input device. Capturing Mac audio needs macOS 14.2 or later. It shares whatever the Mac plays, so Pro Tools comes along with everything else.

3. 03

   Start Sharing and pair

   Press Start Sharing and scan the QR code with the MixOutpost iPhone app or the iPhone Camera. You only pair once per Mac.

4. 04

   Play the session, tap Listen

   Hit play in Pro Tools. The mix comes through on the phone and keeps playing with the screen locked.

Tips for Pro Tools users

• Check the session rate: the stream is 48 kHz. A 48 kHz session is the cleanest match; other rates are converted to 48 kHz for the phone.
• Client in the room: up to eight phones can listen at once, each with its own volume and output. The artist can listen on AirPods while you keep working. See multiple listeners.
• Mute on the phone, not the Mac: each phone has Dim and Mute of its own, so a listener can step out without changing what you hear.
• Post-production checks: the loudness meter includes delivery targets like EBU R128, ATSC A/85 and Netflix, alongside the music services.

What you can check from the phone

Whether the audio comes from the app or, later, the plugin, the checks on the phone are the same: mono and side-only listening, loudness with integrated LUFS and true peak, a diagnostic EQ, and recording to the phone. Keep in mind that with the Mac app, the meters measure everything the Mac plays, so a stray alert will show up in the integrated reading.
