Hi Dan,

I am updating the listener position / orientation rapidly (as the car
moves), I thought I had got it right as when I use look left / look right,
the engine sound pans correctly.  LookAt functions always confuse me heavily
so I could have made a mistake, i'll take another look.

Here is a sample recording if it will offer any clues, taken "in-car"

Thanks for your help!
All the best,
Ash
