It appears that spatialized sound sources go completely silent when your back is to them (unnatural). You can hear them panning left right as you turn away but from, say 11-1 O’Clock they are silent (if sound source is at 6 O’clock behind you).
Of course even with your back to the sound you should still hear it, and I imagine to fake a rear (but both ears) sound it would simply need to be attenuated a little and have some low pass filtering applied automatically to dull it a bit and simulate a rear sound. Also generally and especially with headphones on the sound panning is rather sharp/severe and unnatural when turning, I think perhaps a gentler panning law used here would help (less attenuation in the channels as you turn). Maybe on a TV or something far away that sharpness is needed to hear clearly the position but sounds very fake on headphones. Lots of people use headphones (esp in VR which I’m working with).
I have since added reverb volumes and these work correctly (you can hear a little of the reverberated sound source but still not the original so it sounds weird!)
As always, if I’ve missed some setting or the fault lies with me please let me know and feel free to mark as a non issue!
Even better than fixing this with a kind of sound hack, I would like to assume that with Oculus having licensed RealSpace 3D audio (as announced at connect) that this will find it’s way into UE4 at some point? If so that will be the problem well and truly solved I guess (as the above method I mentioned is hardly ideal but better than silence).
Hi there- sorry to hear you’re having problems with audio. This is an unusual problem; my first impression of the problem is that the audio system is set to Surround, but your listening environment is set to Stereo. That would explain the lack of sound at 180 degrees from the origin of the sound. Maybe can you check that? The UE4 audio system will use whatever the Windows/OSX audio channel count is set to.
Best-
Zak
Well well, thank you! Sure enough it was that, and I never even use surround (I am a musician who uses my external firewire interface for recording and it’s always been set to stereo) however recently the driver for it kept crashing and it appears that during some auto-reinstall it had set it to 5.1! I have just set it back to stereo and confirm it works.
Sorry for entering it as a bug when the fault lies at my end, but thanks for the help and ‘fix’.
