Questions regarding 3D Sounds

[ykykyk]

Hello, I am currently using Vizard 4.0 for a school project. (that is the version installed in the lab).
I would like to know what functionality of DirectSound (or which version) is supported in Vizard 4.0. And to be sure, is sound3d.dx.algorithm supported in Vizard 4.0?

When I was searching from the DirectSound API, there are several parameters that wasn't documented from your side.
For instance,
Rolloff factor

Or other HRTF related parameters
https://msdn.microsoft.com/en-us/library/windows/desktop/mt186604(v=vs.85).aspx
If I am in the correct version of DirectSound API, can you inform me what "default" parameters are used?

I'll have to check with a developer about what the default parameters are. All available commands are listed in the 3D sounds section here (http://docs.worldviz.com/vizard/#Sound_&_Video_Command_Table.htm). The sound3d.dx.algorithm option is supported in Vizard 4. See the global settings page in the Vizard help for more information.
