Hi Dan,

I set the velocity of the listener and sources to their proper velocity
(keeping the positions at 0,0,0) and there were no artifacts.

I am using metres as my unit for everything - I assume I don't need to set
AL_METERS_PER_UNIT in that case?

I don't set any special AL settings - everything is default except
AL_REFERENCE_DISTANCE which i set to 5.0 (although i'm not sure why to be
honest! :)).  I also change the pitch and gain as i go through the revs.

I thought it may have been the order i set the listener / source positions,
but it doesn't seem to make a difference.

Thanks for your help
All the best,
Ash
