Perhaps some of you might be interested how Medivia will look like within a few months, so we have created a short clip showing you the city of Arak with bunch of sounds:
Nowadays Medivia sound engine is based on fmod which is used in a lot of AAA games. Certain sound sources (e.g. a torch as seen on the video) are fully localized in 3D space of the game. Besides that a Doppler effect is calculated as well. This can be fully heard when running towards or from the torch. Doppler effect will apply to missiles as well which does change the sound a lot depending where is the effect being shown and what velocity it has (it may vary).
Keep in mind that adding a lot of sound effects is quite easy, but obviously we do not wish to be overwhelmed with sound in general otherwise it would turn out to be a painful experience.
