Audio transport over any network, peer-to-peer and low-latency.
Send and receive up to 128 channels of low-latency audio between your Macs — across the open internet or on a local network. Works with any Core Audio device,
including Dante Virtual Soundcard.
- macOS 14+ · Apple Silicon & Intel
- Audio is direct — never relayed
- No connection limit
Direct audio between your Macs.
OD Link connects your Macs directly over IP. Every connection runs both ways, and one Mac can hold many connections at once — route audio between rooms, machines, and sessions however you need. On each Mac, pick a capture and a playback device, patch your channels, and it flows straight between them over UDP. No extra hardware, no cloud to trust, no monthly bill. Built for studios, live sound, broadcast, and remote sessions.
Your whole patch in one window.
Pick your audio device, then map inputs to the link — auto-patch 1:1 or set crosspoints by hand. Live input meters, with per-connection latency and mode, all in one view.
Engineered for professional audio.

Three steps to a live connection.
Install on every Mac
Download OD Link and open it on each Mac. On first launch, allow Microphone (to capture audio) and Local Network access when macOS asks.
Connect
On each Mac, add a connection to the other and enter its IP — or, with a Pro or Performance license, turn on UDP Match to connect by name, with no IP to exchange.
Patch & play
Pick your capture and playback devices, patch the channels (auto or by hand), and the audio flows straight between your Macs.
One app. Pick your scale.
Every paid license is perpetual — pay once, own it. Prices in USD.

Built for people who can't afford a dropout.
Direct, never relayed
Audio is pure peer-to-peer UDP. It never touches any servers — lower latency, and your sound stays between your machines.
Pay once, own it
A perpetual license, not a subscription. No monthly fee, no cloud login.
Rides out packet loss
Error correction, retransmission, and an adaptive receive buffer absorb the hiccups any real network throws — so a lost packet doesn't become a dropout.
Fits your rig
Works with any Core Audio device — your interface, an aggregate, or Dante Virtual Soundcard — up to 128 channels.
The Demo is the whole app.
Run the full OD Link with 32 channels, free, with no signup. From time to time it briefly mutes the audio with a watermark — just enough to hear the real thing before you buy your license.
