Loopback routes multiple audio sources out to your radio station. Whether you’re using iTunes, Spotify, or a microphone, easily organise and send them to places like Skype or a broadcaster like BUTT on your Mac.

Loopback Setup

Download Loopback. Open the zip and add it your Mac’s Applications folder. When you open Loopback, the home menu appears.

Loopback home screen.

Select the + New Virtual Device button - “Loopback Audio” appears (you can change it to another name later on if you want).

Above your inputs click on the + button, then choose the applications or devices you want to capture audio from. For instance, Spotify, Google Chrome, a microphone, etc.

You can delete any device or application, just select it and click on the Delete button at the bottom of the screen.

Next, go to the Sound Settings on your Mac; select Loopback Audio (or whatever you named it) so it's now your input device.

Broadcast to Radio.co

Send out your routed audio to your radio station online. For Loopback to work with Radio.co, you need a broadcasting tool such as BUTT which you can download here.

Within BUTT, add your Radio.co broadcasting details. You can find these within your Radio.co Dashboard.

Once BUTT is open, set it up!

  • Select Settings, then under Server Settings click ADD.

  • Enter your live broadcasting details then click ADD.

  • Next click Save.
