Livestream Studio’s built-in audio mixer can be found in the lower left corner of the interface under the Audio tab.
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 also has two 1/4-inch XLR combo inputs built in).
We have successfully tested Onyx and M-Audio mixers with Livestream Studio. Generally speaking, any device your operating system--Windows or Mac--supports will work with Livestream Studio, although we recommend using audio devices that do not require drivers to be installed.
Studio does not support virtual audio sources such as Virtual Audio Cable or similar software. As a workaround, if your sound is coming from your computer, consider enabling screencapturing with the audio source enabled in the mixer.
To add these sources, navigate to Inputs > Add Input > Audio Only. Choose your source from the menu that pops open. You can add up to eight (8) Audio Only sources.
If your device is not recognized, check to see if it needs to have drivers installed.
Livestream Studio will automatically label the source (e.g., AUDIO1). Hover your cursor over the name and then select the pencil icon that appears to edit it if you wish.
This source can also be assigned to a track on Studio Surface if you have one connected.
You should now see your audio source included with your other sources in the Audio Mixer.
