The trip back from Taiwan was slightly brutal – I always have a harder time going east than west. I’m not sure why. But I was smart, and I charged up all four batteries for the trip. One of the things I was able to get done when I wasn’t sleeping was to write the last in the DirectSound tutorial series. You can find it here. It talks about how to add listener-relative positioning and velocity, which gives you control over things like Doppler shift.
I think after this I’ll go back to writing the Direct3D series. There seems to be more interest in it, and since I did a bunch of reading while waiting for various conversations in Chinese to complete, I have some more knowledge of the areas I’d like to explore.
