Maybe you are calculating the velocity as m/frame instead of m/s?
Or you transformed the m/frame

At least I've found the reason for this
Thanks to the help of Tim I am now really close to properly aligned,
positioned and orientated sounds.
Now for the bad part, except for Tower View and Fly-By View the
orientation (and relative position) seem to have no effect?

Hi Tim and John,
First, thanks for looking at this, it has really given me headaches.

Hm that's an oversight, it should not be in Cartesian spa

Not really, I need a (normalized) 3d v

At this time I've tried about everything to get the listener orientation
aligned properly. What's needed it converting the ViewOrientation matrix
(quaternation) and/or ViewOrientationOffset matrix (quaternation) to
align with OpenGL and get the look-at and look-up vector from it.
