if you need the raw audiodata for every channel I think you have to use a custom audio device. I'm not familar with that but it is possible to write own audio devices for J3D. The specification for Java 3D 1.2.x contains detailled information about how to do that (more than the JavaDocs from 1.3.x ;-)

Hi,
Thank you so much Michael for your comments.
Actually what I need to do is to duplicate a sound stream in 2 audio streams, and then apply a specific digital filter to each of them. Then one audio stream will be sent to the left ear of the headphones and the other one to the right ear. The audio spatialization effect is done by the filters, each filter having particular coefficients. Clearly I need to provide binaural audio from my application that is using the Java Media Framework API.
Is that more clear to you Mickael?
Cheers. :)

Hi,
I'm not sure what you mean with "spatial" - a real 3D-sound which not only comes from left and right but also from front and back or a "simple" stereosound. The second one can be realized easy. When you attach Sound-Nodes to other objects or to several positions within your scene and move and rotate between them, Java 3D does everything for you. You only have to initialize the AudioDevice e.g. with
AudioDevice auDev=simpleUniverse.createAudioDevice(); auDev.setAudioPlaybackType(AudioDevice.HEADPHONES);
and then add Pointsound- and Conesound-objects in the same way as you'd do it with other Nodes.
For real spatial sound effects with headphones I afraid you have to go deeper inside and write your own audio device which calculates some kind of virtual surround out of the three-dimensional positions of the sound sources. But that would be an really advanced algorithm.

Hi everybody,
I wish you first a very happy new year. :)
I am very keen to provide spatial audio with the headphones of my computer.
Does anyone know how to control the left and right audio channels of the headphones with the help of the Java 3D API? Examples?
Cheers. :)
