It would be for off-camera audio (voice over, music etc.) that don't have any relation to the camera position/rotation. Imagine a video with an on-camera actor (dialog), a voice over and a music track. You would want the on-camera dialog to match the video position (so counter-rotate) , but the VO and music track will not rotate. > > if you absolutely have to do it, the only way is to deliver two streams, > one head-tracked and counter-rotated, the other not. which means you'd > have to have control over the listener's player software.
