[SUPPORT] AudioAnalyzer

You need to select the input audio device using “Set Default Device Loopback Audio” node instead of the system default for an instance of the AudioAnalyzerManager.

You can use “Get Output Audio Devices” node to retrieve a list of found devices, and see if the interface is in that list, use this name as input of “Set Default Device Loopback Audio” node.

WINAPI takes the audio output pipeline of the selected device and I feed that data to the analyzer using a buffer, if your device appears in the list of audio devices in the windows audio settings then is must be available to be captured by the plugin.

Also, if you have any log of UE4 using your device with the plugin we can check if an error has occurred for that especific device.

Well, I’m just using your loopback demo to test all this out atm and that node is already there. Right?

I “think” the main issue while I can specify my device I have no way to specify which port to use. I have 28 in and 28 out on my interface. Now, here’s the thing. After facerolling for a bit I figured out that if I have OBS on and I have monitor enabled NOW I am getting audio in UE4.

It’s just really weird because I believe it’s doing a double loopback here. External audio device > interface > loopback internally in the interface > windows > obs > windows loopback > UE4 this might need explaining.

My CDJ’s are outputting XLR to my interface.
My interface routes that audio to multiple hardware outputs. It also does a loopback on any channel I specify.
The interface does a loopback taking channel 1-2 into windows.
Now windows can hear the interface audio which means OBS can hear it. At this point UE4 does not hear the audio.
Within OBS I can set the audio to monitor and output to stream. If I have output only, no sound in UE4. If I enable monitor I get sound in UE4. This is the secondary loopback.

I feel like something in UE4 is missing atm as OBS is able to hear the audio but not UE4, until I loopback into Windows again.

Right now it is working but this is a bandaid so I would really like to get to the bottom of the main issue to prevent further headache down the road.

Thanks for your reply!

Edit: Quick edit here, I was doing more testing just now and in the other demo it allows me to select mic which is taking the same audio that OBS was taking. But OBS is off. I went back inito the loopback demo to test with OBS off and same results, did not work. Went back to the demo level (A_StarterProject_424) and it is still working. So whatever Mic is pulling in, is getting the loopback from the interface.
