I am just getting into sound within Java3d and throught I would ask a few questions.
1. We have regions which we want to attach ambient sounds to. (Regions are arbitrary polygon bounded areas on the landscape) As you approach a new region we want to ambient sound of the current region to decrease and the ambient sound in the new region to increase. I understand you can have to background sounds which can be mixed. Should we have behaviors which manage the gain on the various background sound nodes to handle this? We can't use a point sound because it really isn't a point. 2. It has been remarked that sound causes performance degregation, but I am not sure to what extent. Assuming we have at least one background sound and 3-4 point sounds with an occasional cone sound what sort of degregation would we be likely to have? Is this a CPU / Thread thrashing problem? Has anyone checked to see if j3d 1.3 has improvements on this? 3. In some cases we have thin regions running through bigger regions. In these conditions we would have both regions operating within hearing. An example would be a stream running through a forest. There is the sound of the stream and the sound of the forest. Is this a condition where we should set the priority of the sounds? Is the priority only there in case there are not enough channels to handle the number of sounds which need to be mixed? 4. If we want to attach different soundscape leafs within our scenegraph, is it enough that the leaf exist within the sub-scene that has the sound nodes? So for example if someone walks from a sandy beach into a cave, and we have the soundscape leaf for more reverberation in the sub-scene that has the cave will that guarentee that point sounds change properly. So for example if the point sound was footsteps do we need to detatch the sound from the "outside" scene and place it in the "inside" scene for the effect to work? Or is the design that it is hierarchical, with the outside (with its soundscape leaf) being "higher" than the interior subgraph?
