I think people have thought about this, not only for poser, but for many other applications. The entire 3d sound is more like a game engine implementation than anything else, so I don't know how it would work in Poser. On the other hand, the reason people don't put these features inside applications is because they assume users will render out the still images (frames) and then use a NLE application to edit, add sound, music, etc.
