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

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

Thanks for the hints and links John, I really appreciate it.
It covers various ways of representing rotations, including
product-of-vectors i.e. Clifford algebra i.e.

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.

Erik,
I'm not good at this stuff at all, but I just remembered that the mpmap
code recovers yaw, pitch and roll from the quaternion passed in the
multiplayer message... Is that what you need? Or is that where you
started from?
Not really, I need a (normalized) 3d vector

I suspect there still is a positioning or orientation problem hiding
somewhere that's causing it. My speed lessons in quaternations don't pay
