Livestream Studio’s built-in audio mixer can be found in the lower left corner of the interface.
Each input source will have a corresponding audio source that you can monitor and adjust.
You may have a separate audio mixer or a microphone can connect to your system directly via USB or line-in (the HD550 has two 1/8-inch & XLR combo inputs built in). You use the 'Audio In' tab in settings to control the audio.
Press the ‘+’ button at the bottom of the window to add an audio source.
Under ‘Audio Source,’ click the dropdown menu to select your source.
Note: If your device is not recognized, check to see if it needs drivers installed.
Livestream Studio will automatically label the source (e.g., ‘AUDIO1’). Click on the name if you wish to change it.
This source can also be assigned to a track on Studio Surface if you have one connected. Otherwise, ‘None’ will be the only option available.
Click ‘Save’ in settings. You should now see your audio source included with your other sources in the Audio Mixer.
