On a Mac, setting up for streaming is a bit easier than it is on Windows. This is because of the way Windows and Mac handle ASIO and audio. On a Mac you can create an aggregate device, which is like a virtual device; but, on Windows, this concept does not exist in the OS. However, there are a couple of ways to get Studio One audio to a livestream application such as OBS. Here they are:
- You need an audio interface that has loopback capability (our Studio Series of interfaces has this and is available in Universal Control. Other non-PreSonus devices will vary and have different functionality)
- In Universal Control Set the loopback box to Virtual
- In Studio One, in the I/O via song setup or the I/O button in the mixer, create a new stereo input. Call it Virtual 1&2 and assign it to the virtual 1 & 2 at the end of the matrix.
- In OBS go to Settings > Audio and set your mic input to the line in your interface that your mic is plugged into and set the Aux as Virtual 1&2
- In OBS create a scene and in the audio mixer You should see your two audio sources. Name the one that has the Line in as its input "Mic" and the other one "DAW". Click the cog for the "Mic". Adjust the gain so it is louder than your DAW audio a bit and also check the mono box.
If your interface does not support loopback, you will need to use the following method. To complete this method, you will need either a secondary interface or you can use the soundcard built into your computer if it has one:
The Two Interface Method
- Route the outputs of your main interface to the inputs of a 2nd interface. Take a pair of TRS cables and connect them to the outputs of your main interface and the inputs of your secondary interface
- In OBS set this 2nd interface as your Mic input.
