Broadcast Live Radio With Multiple Presenters

Do you want to broadcast live radio with multiple presenters? Invite fellow presenters and guests to liven up your shows. Here's everything you need to know to get up and running.

This guide focuses on a Mac setup. If you have a Windows or Linux machine then contact support for advice.

Setting Up Your Computer's Audio

Download Soundflower. It's a Mac OS application that allows you to pass audio to other applications. It essentially grabs your computer's audio and sends it elsewhere.

Once installed, restart your Mac. Open up Audio MIDI Setup by searching for it in spotlight (command + spacebar).

Searching Audio MIDI - Broadcast Live Radio with Multiple Presenters

Audio devices shows all your input and output devices like microphones, mixers, and headphones. Click the + button and select Create Multi-Output Device, then update the new output device settings.

  • Sample Rate: 44.1 kHz
  • Audio Devices: Soundflower (2ch) and your headphones/earphones (in this case, Bluedio F2)

Download LineIn. It enables play thru of audio from physical input devices, such as a microphone or mixer.

Once open, in the input dropdown select your microphone (in this case we're using the Rode Podcaster). In the output drop-down select Soundflower (2ch), then click Play Thru. LineIn will send your input device's audio to Soundflower, which is grouped together in your multichannel output.

LineIn Multiple Presenters

Open up your sound settings in System Preferences > Sound. In Input, select Soundflower (2ch).

Use the Input Volume to control your computer's master volume level that goes out to your radio station. In Output, select Multi-Output Device.

Inviting Guests Using Cleanfeed

Cleanfeed is a free audio streaming service for group chats. The idea is to use it as a group chat to talk with your fellow presenters or guests. Connect two or more people from Mac, Windows, Linux, or Android.

Cleanfeed uses your default microphone. Change this if you want to set it to an external mic by clicking the video camera icon in your URL bar, then choose Manage Media Settings.

Invite guests by selecting Connect and filling out your presenter's details.
