Stream Studio One to your iPhone

Set it up in Studio One

1. 01

   Install and rescan

   Run the free MixOutpost installer and choose the Audio Unit (and the VST3 if you like). Studio One scans for new plugins when it starts, so restart it if MixOutpost doesn't show in the browser.

2. 02

   Insert it last on the Main out

   In the Console, add MixOutpost to the bottom of the Main out's insert rack, after your limiter and any metering, so the phone hears what your monitors hear.

3. 03

   Start Sharing and pair

   Press Start Sharing in the plugin window and scan the QR code with the MixOutpost app or the iPhone Camera. One pairing covers every instance on the Mac.

4. 04

   Play and tap Listen

   Start the song. It plays on the phone, and keeps playing with the screen locked.

Tips for Studio One users

• Save it in your default song template: if you always check on the phone, keep MixOutpost on the Main out of your template. Sharing never starts on its own when a song opens; you still press Start Sharing.
• Let the band listen: during a playback break, band members can pair their own phones and hear the rough mix with their own volume and AirPods. See multiple listeners.
• Buses as sources: add a second instance to a vocal bus or a drum bus. It appears as its own source on the phone, and Compare switches between the full mix and the bus, with click-free switching and a volume per source for matching levels.
• Mastering chain first: if you master in the song itself, keep MixOutpost after the whole chain so loudness readings on the phone reflect the finished level.
• Mixdowns are safe: the plugin passes audio through unchanged and skips offline exports.

What you can check from the phone

With the song on your iPhone, the useful checks before release are loudness (integrated LUFS and true peak against targets like Spotify, Apple Music and YouTube), mono compatibility, and how the low end holds up on a phone speaker with the diagnostic EQ. You can record a bit-exact WAV on the phone, too, so you have a reference without exporting.

Sample rate and quality

The stream to the phone is 48 kHz. If your song is set to 48 kHz, the phone gets a bit-exact copy of the Main out, and the connection info in the app says so. Songs at 44.1, 88.2 or 96 kHz are converted to 48 kHz with high-quality sample-rate conversion on the way to the phone. Studio One's own output isn't touched either way. Audio is encrypted with TLS 1.3 and only paired phones can listen.

Why not just export and AirDrop?

Exporting works, but every change means another export. Streaming lets you move a fader and hear the result on the phone a moment later. The trade-offs are covered in MixOutpost vs bounce and AirDrop.
