JACKPilot

​Free software

To download the software use the link below:​
https://jackaudio.org/downloads/

And choose to download JACK2 binaries:

After restarting your computer when the installation is finished, open the app JackPilot.
 
The “Preferences” window should show up when you open the app for the first time. If not, open it by clicking on the JackPilot/Preferences in the upper right corner.
 
In the Preferences window choose leave the “Built-in Microphone” and “Built-in Output” in the devices settings. Set the Sample Rate to 48000 and set the number of Virtual Input and Output channels to 4. Click Save.

Then, press the “Start" button.

Now go to OBS and specify the amount of input channels to 4 and select the JackRouter as an input device (Mic/Auxillary Audio).

 Click OK to save the settings. You might have to restart the OBS.
 
Then, open the Reaper project called “ZM-1 FOA Streaming via JackPilot.RPP”. If you haven’t connected your ZYLIA microphone array already, do it now. Go to preferences and select ZYLIA as an Input Device and JackRouter as an Output Device. You have to tick the box marked in the image below to allow use of different input and output devices.

After choosing the right settings click OK. Now there should be some signal coming from the ZYLIA array.

Then head back to JackPilot. Now press the “Routing” button.

“Connections Manager” window should appear.

In the Connections Manager window click on the two triangles highlighted in the image below. The Send Ports/REAPER list shows the output channels from Reaper, and the Receive Ports/obs list shows the input channels in OBS. There should be 4 channels per each list. Remember, that first you have to choose JackRouter as an Input Device in OBS and as an Output Device in Reaper for the channels show up in the JackPilot’s Connections Manager window.

Then, click on the “out1” item on the “Send Ports” list. ​

With the “out1” item selected, double click on the “in1” item on the “Receive Ports” list. It should change the colour to red. This means, that output channel 1 from Reaper is routed to input 1 in OBS.

Now do the same with the rest of the channels:​

Out1 -> in1
Out2 -> in2
Out3 -> in3
Out4 -> in4

Now everything is set up and you should be able to stream first order ambisonics captured with your Zylia!
