Hear the difference between what spacial audio can bring. Ambisonics can be a powerful tool in creating a soundscape. Unreal Engine has the power to make these Ambisonic recordings be used to their fullest.
I show you a small example of an in depth collection of drag ’n drop, professional Ambisonic, and HD Stereo recordings. Every audio asset you need to create ambient forests vibrant and alive. Good for VR, games, documentaries, video, background ambience and more.

Hi David, thanks for the video! Do you think it works properly also with a binaural .wav file (2 channels), or in order to achieve this results you may need a 4 channel ambisonic file? thx
this is great - are there any applications for ambisonic music or would you say its main strength is in environment sounds?
I’ve thought about that specifically for the game world: depending on how the game is set up, having an interactive score that even changes more by focusing on different instrumentation depending on character placement. Looking to the right focuses more on the instrumentation that’s placed in that 3d area. The character looks up, then the music fades in more to a different set of instruments. There would have to be a lot of forethought in how the arrangement is and a series of other factors, but I think that concept is cool, and when I have time (hahaha) I want to dive into making a concept for 3D musical arrangements in game play
Hey! great stuff, would you please share how you setup ambisonics in ue4? I can't seem to figure out how to do the setup. Thanks :)
Thank you for the reply!
as long as the file name ends in .fuma or .ambix, unreal automatically assigns it as "is ambisonic" when looking at the wave info. Here's more info: docs.unrealengine.com/4.27/en-US/WorkingWithAudio/Nativesoundfield/
One thing to note is that Unreal Documentation has it wrong when explaining the ordering of channels: FuMa is in fact W,X,Y,Z and ambiX is W,Y,Z,X.
I use FuMa in my projects as it sounds more natural and closer to what I've recorded.
Here's more info I've written in a "fairly" easier way to understand ambisonics: ambisonicspaces.org/blog/f/using-ambisonics
Great video! How would you achieve binaural in UE? Do you just record with an ambi mic for every sound effect or do you process the stereo files. If so, how do you go about it?
Thank you! If I understand you correctly, wav files imported into UE are already encoded into Ambisonic. As far as I know, I don’t think UE can decode those wavs into a binaural render. However, there are many tools like Ambisonic Tool Kit for daws like reaper that can decode those Ambisonic files into binaural renders. Ambisonic 1st order is a 4 channel file, binaural renders of ambisonics make a 2 channel track (stereo). The engine does a great job of managing ambisonics and stereo together as long as you configure everything correctly. Hope that helps :)
@@davidwoje2044 Sure did, thanks!
Hi, thank you for your video: is it possible to make a Google resonance audio source simulation with simple stereo tracks? I'd like to make a violinist play in an accurate 3D but I don't have the ambisonic track. Or is there a way to convert it?
Thank you for watching🙏. There are plugins that can encode stereo to polyphonic tracks. plugins.iem.at/ I personally haven’t used them yet (as I thankfully have the ability to record ambisonics) please share what you create 🙂
great, thank you, do you have any lead how to use 8 channel ambisonics in Unreal?
The last time I checked Unreal documentation, the engine supports 1st Order ambiX and FuMa. So only 4 channel.
@@davidwoje2044 I thought about custom plugin or code. I'll check that
Hi David,
is there a way to get your sounds out of UE? I've rendered a 360/vr presentation and want to bring your ambisonic sounds now in Adobe Premiere.
Hey there! Right click the asset, go to > Asset Actions > Export! That should do the trick.
@@davidwoje2044 I don't know why RUclips keeps me from posting comments in here? #notabadguy :D. This is now my third comment, if this gets through and the others will also be released afterwards...sorry for the confusion, David. I get it now _fl (front left), _fr (front right)...etc..
