@GrobiThee This should happen when the audio team embraces Microsoft’s new Spatial Sound API (UE 5.0?). Sadly until this is done even if you have a Dolby Atmos system with ‘height’ speakers you will not be able accurately position “audio actors” to duplicate this. I know, I have tried it doing some testing with creating an export of a multiple channel (max 8 channels still) WAV as I found using a virtual audio device with 12 channels which are labeled to act like Windows new Spatial Audio API. The way I have been able to accomplish ‘Z’ for creating Ambisonic 1st & 2nd order Ambisonic audio and Dolby Atmos is to just roll (X axis) 90 degrees and run a second pass in a sequencer event. I am finishing up tutorial on how to do this, this week in using my latest video teaser for my Mar’s Perseverance & Ingenuity Drone simulator. However I found the 7.1, which is suppose to add two side audio channels, does not work correctly in Unreal. Having created a virtual geodesic frame that I mounted my ‘Audio Clients’ to with neat little animated effect to show which speaker is running, I noticed no audio coming out of my side speakers, which is confirmed in reviewing the 8-channel WAV file. In fact the best way is to just use 5.1 audio device and which does seem to mix properly between front and back to give you side. Also, even though ± 30 degrees offset for front and back is great for speaker placement, It would be nice have them at 45 degrees, which would give equal power at proper cosine power points. Not a big problem for me because I can use my Amisonic VST encoder in my DAW or LRE to place the points with reasonable positioning achieved. You may ask why I am going through the trouble of doing this in Unreal instead of just building the soundfield in a DAW? Frankly it seems like wasted time and it does not sound the same – especially now that you can do so much more in Unreal like the inclusion of doppler, reverb, convolution audio that to duplicate it in a DAW seems redundant and time wasting. Plus, I like knowing when I put a sound actor in 3D space in Unreal, I get pretty facsimile of that sound’s location. Something I have not seen any DAW do well unless you pay for expensive “3D” visualization plugin. Even Facebook’s Spatial Workstation plugins leave a lot to be desired even though you can don a VR headset and get pseudo 3-axis positioning.
There is Wwise solution that some AAA developers are using, but it requires you add their plugin and even do a little recompiling to recognize Dolby Atmos. Plus it cost money.
