In this video we see how to use sound speakers in a 3D scene, to get sounds that are spatialized around the active camera. We see also how to delay the sounds and replay a same sound with a single sound speaker. Finally how to render separately sound and picture to merge then in video editing.
This video is english spoken. As english is not my mother tongue I hope it will be understandable... if some parts are not clear, do not hesitate to add a comment and I will edit subtitles. ^^
