Free · Mac, Windows & Linux
Play it on one computer. Hear it on all the others.
lanaudio sends sound from one machine to any number of others on the same network. Each one sees it as a normal input for OBS, Zoom or your DAW. No cables, no audio interfaces, no IP addresses. And when everyone should hear it, go live: anyone with your link listens in a browser.
Also for Windows and Linux. Version 0.4.0.
New: a station of your own, free with an account.

Built for
The studio Mac in one room, the stream in another.
Your mix stays where it is. Every other computer on the network just picks it up.
Three steps.
Then you forget it's there.
Install it on every computer that needs to send or hear audio. That's the whole setup.
Install once
The app adds a virtual sound device called lanaudio. On a Mac you type your password one time. Linux needs one click, and Windows needs nothing.
Send
Point your DAW or system output at lanaudio and press Start sending. Other computers see you by name.
Listen
On the other computer, click the sender's name. In OBS, add Audio Input Capture and pick lanaudio.
No app? No problem.
Listen in a browser.
Switch on one setting before you press Start sending. Listeners press play and hear you about a second behind live.
Scan and play
Phones and laptops on the same network scan the QR code in the app, or open its address, and press play. Nothing to install.
Share one link
Turn on Go live and anyone with your link can listen, from anywhere. The link belongs to your computer and stays the same.
It's a radio stream
The stream is plain MP3 at 192 kbps, so VLC and most radio apps play it too.
A station of your own.
Free, with an account.
You don't need an account to send, listen or go live: each computer has its own link. An account gives you a station that's yours, with one name and one link, that any of your computers can go live on.
Name your station
Make a free account, then pick your station's name and its link, like …/kofi-fm. The link never changes, so you share it once.
Link your computers
In the app, choose your station. It shows a code, and you approve it on your dashboard. Unlink a computer any time.
Go live from any of them
The studio Mac today, the laptop on the road tomorrow. Listeners use the same link every time, in a browser or any radio app.
Free: one station, up to 50 listeners at once.
Linking a computer from the app arrives with the next app update. Make your account and station now.
Spec sheet

Platforms
Questions people ask
Is it free?
Yes. Sending, listening and going live need no account and no subscription. A free account adds a station of your own.
What's an account for?
A station that's yours: a name and a link that never change, which any computer you link can go live on. Your dashboard has the links to share and the computers that can go live. Free: one station, up to 50 listeners at once.
macOS says it can't check the app for malware.
Apple shows that for developers outside its paid program. Approve it once in System Settings → Privacy & Security → Open Anyway.
Windows says it protected my PC.
That's SmartScreen meeting a new app. Click More info, then Run anyway. You do it once.
How much delay should I expect?
About 20–40 ms on a wired network. On a busy Wi-Fi it can climb to 100–200 ms, then drops back once the network settles.
Wi-Fi or Ethernet?
Both work. A cable on the sending computer helps the most. On Wi-Fi, 5 GHz beats 2.4 GHz.
Can I send over the internet?
For listening, yes: Go live gives you a link anyone can open in a browser, anywhere. Sending into another computer's OBS or DAW over the internet is still on the roadmap.
What is the virtual device?
A small virtual sound card. On Mac it's built on the open-source BlackHole driver (GPL-3.0); on Linux your sound system makes it. You can remove it any time.
