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.

They are in j3daudio.jar:
$ jar -tf
j3daudio.jar | grep
Headspace
com/sun/j3d/audioengines/headspace/HeadspaceMixer.class
com/sun/j3d/audioengines/headspace/HeadspaceParams.class

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!
