Add desktop audio as a source

note

If you do not need to stream audio from your workstation, you can skip this step.

An additional audio driver is required to capture desktop audio on macOS. The two options available to capture system audio are and Loopback ($119 one-time purchase, with a free trial) and Blackhole (free). Whilst Loopback is a paid option, it does provide finer control over how system your audio is captured, routed and monitored and is what we recommend for best performance.

View steps
  • Download and install Loopback here
  • Open Loopback and click the + icon in the bottom left to add a new virtual audio device
  • Turn off Pass-Thru in the Sources list
  • Click the + icon next to Sources and select the application that you require audio from. You can add multiple applications if required
  • In LBS, click the + icon at the bottom of the Sources panel and select Audio Input Capture
  • In the Device dropdown, select Loopback Audio and click OK
  • In order to hear the audio, navigate to the Audio Mixer panel and select your desired audio output device (ie. your speakers or headphones) in the Monitoring Device dropdown
  • Click the headphones icon to enable audio monitoring

note

Adjusting your Mac's volume when using Loopback will not affect your stream's audio level.


Blackhole​

View steps
caution

If you are using Blackhole to capture desktop sound on macOS and video / voice chat is enabled in your Louper room, it is strongly recommended to join your Louper room from a separate device to avoid audio echo between you and your guests.

  • Download the Blackhole audio driver here
  • Double-click the downloaded package and follow the prompts to install Blackhole
  • Click the volume icon in the menu bar of your Mac and select Blackhole 2ch as the audio output device
  • In LBS, click the + icon at the bottom of the Sources panel and select Audio Input Capture
  • In the Device dropdown, select Blackhole 2ch and click OK
  • In order to hear the audio, audio monitoring must be enabled in LBS. Navigate to the Audio Mixer panel and select your desired audio output device (ie. your speakers or headphones) in the Monitoring Device dropdown
  • Click the headphones icon to enable audio monitoring
note

Adjusting your Mac's volume when using Blackhole will affect your stream's audio level. For example, muting the volume on your Mac will also mute your stream's audio for your participants.
