MVRsimulation VRSG's sound generation support enables you to add sounds to events and entities in a virtual world. The 3D sound support uses the DirectSound and DirectSound3D API (part of the Microsoft DirectX SDK ) to achieve an integrated visual and audio capability on a personal computer. DirectSound and DirectSound3D provide low-latency sound mixing, hardware acceleration, and direct access to the sound device in a hardware independent manner.

The close coupling of Direct3D and DirectSound provide 3D sound in VRSG with a minimum reduction in frame rate. DirectSound and Direct3D achieve an integrated visual and audio capability on a Windows-based personal computer.

DirectSound supports the following features that are supported by a large number of PC sound card providers:

  • Perception of sound positions
  • Listeners
  • Sound cones
  • Minimum and maximum distances
  • Position versus velocity
  • Integration with Direct3D
  • Units of measure and distance factors
  • Mono and stereo sources

You can easily add sounds to a virtual world by using sound sampling software (standard with most sound cards) to record the sound required to be associated with a particular event. Many commercial sound libraries exist that will provide inexpensive audio CDs for any sound you could imagine. You then add the resulting *.WAV file to a VRSG Windows configuration file and associate with a DIS enumeration event.
