Moving Sounds in DirectX DirectSound

I want to create a sound that starts in the left ear and ends in the right ear. I would prefer to set the parameters and have the sound move. I don't want to put a sound in at one point and have it looping and then move its position. Think of a bullet getting shot and the sound going from the left to the right. The sounds I am using are short and so it would move quickly from one ear to the other. Thanks for your help.

You can use something they put together in direct sound (3d sound) but dont forget you can actually manually make it too and fake all the speaker interaction and doppler shift... sorry i cant be any more help than that.
