Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Exporting Ambisonic Audio

Hi Guys,

So after I finished my VR project I wanted to create a 360 video of it to display to others without a Oculus Rift/ HTC Vive headset. Using the Stereo Panoramic Movie Capture plugin by Kite & Lightning I've got together a great PNG sequence for left and right eye that I've put through After Effects and everything works perfectly. However, audio has become a major problem. I have exported the audio as a stereo .wav by recording internally, but after much research I've been discovering ambisonic audio and all it's complexities. I've attempted to recreate the audio from the VR experience but it's impossible to make the sound source dynamic and moveable, rendering the method useless. What I'm looking for is a method of getting the audio from the engine straight into a 4 channel ambisonic track. If anyone else has faced this issue please share how you overcame it. Thanks!

Product Version: UE 4.18

Hi, did you find out any way to record ambisonic audio from Unreal Engine?

Unfortunately not, I ended up just using the stereo track. My best guess would be that you would require a piece of hardware capable of recording 4 tracks (i.e. mixing desk) and internally record the audio using software such as Adobe Audition onto a AmbiX track. Then use metadata injection to track the ambiX ANC/SN3D file to the video
