Environmental Utilities from TOGA Projects to start with ENVSOUND.
TOGA Projects has announced it will release ENVSOUND, one of their new line of ENV products for Prepar3D and FSX. The ENVSOUND utility will replace the default sounds and make them more realistic. Some of the sound which will be replaced include coastal ambiance, city ambiance, and weather ambiance. At release, over 80,000 locations will include these sounds and more will be added as the utility is updated.
You may look for it at simMarket soon, and the price will be very reasonable. Their announcement was made through our friends at FSElite and you can read all about it here, including a feature list.
