I have been uploading 360 videos to the 360 Videos folder on the Samsung Gear VR micro SD card for some time now. All these videos have been with stereo sound. I am now ready to upload videos with 360 binaural sound, which will respond the motion of the head and stay in sync with the changing video. How can I do this? I see that the Strangers Patrick Watson video has separate sound files. Is this the way to go?
