java3d 1.3, and 3 different betas from 1.3.1, all of which
contain the HeadSpaceMixer class in j3daudio.jar.

Thank you for the information. But I can not find the headspace/HeadspaceMixer.class in my package. There is only a com/sun/j3d/audioengine.class. Why? What version of J3D are you using? Or do I need to downloaded a seperate 3D audio?
Best, G.B.

- Hi:
- In your code, there is an import:
- import com.sun.j3d.audioengines.headspace.HeadspaceMixer;
- Please tell me where to find headspace.HeadspaceMixer?
- Thank you!
