UE 4.19 native spatialization, how to use?

Also, while you’re checking out the UVOIPTalker stuff, I should also mention that you can create a blueprint child class of UVOIPTalker, and in doing so get events for when the registered talker starts and stops speaking:

For example, here I’m just playing a sound when someone starts and stops talking to create a sort of “walkie talkie” effect. If the person speaking is on Windows, this will also take silence detection into account, so you will get Begin Talking events when someone actually starts speaking and End Talking events when they stop, even if you’re not using push to talk or if someone is keeping their push to talk button held down.

Let me know what kind of rad stuff you use the VOIPTalker for!

@Ethan.Geller, could you please elaborate on this? We’ve created a blueprint child class of UVOIPTalker and have put the nodes in there as per your screenshot, however how does this blueprint get loaded in the game? Does it get spawned by the character bp on beginplay? We want to use it to play beeps and clicks to simulate a military radio.

Also, would you be able to point us in the right direction on how to use source effects chains to make VOIP sound like military radio? I’ve found some guides on youtube for other audio programs but I couldn’t find anything for UE4. I know that vaguely we want to use high/low pass filters but I don’t know what settings to have them at.

Lastly, is there any way we can reduce the latency of the VOIP chat? Our users are typically playing in the same room (over LAN) which makes the latency quite noticeable.
