Hello everyone,
How is it possible to make a sound look like coming from behind the player?
What I want to do is to put something like an external talking voice which come from behind, I have tried usine Play Sound Location in Blueprint, setting the Location as the Player Location + Another Vector which i set up, but it doesn’t change anything.
Thank you,
Amus
Hello,
I may be reading more into what you are asking, but are you talking like a Narration that follows a player around? Or are you simply asking to have a sound play at a location which is relative to the player’s location (meaning if the character turns around, the sound is behind him; if the character turns to the right of the sound, it emits from the characters left, etc.)

In order to make audio appear to come from behind, you’ll need to use something like HRTF ( Head-related transfer function - Wikipedia ) filtering on the original audio. This would be done in an external application prior to importing the final wav-file into UE4. If you have an audio editor that supports VST (should be most of them) you could experiment with, for example, this one: http://www.savioursofsoul.de/Christian/se-modules/dsp-modules/ (scroll down to HRTF 3D).
Once tweaked to perfection, you would probably use the wav in UE4 as a non-directional source to ensure that there is no additional spatialization done by the engine.
