The standalone version of the popular Crysis singleplayer modification Wreckage is available for download. Wreckage offers an action-oriented presentation, professional execution, complete dubbing and Crysis-level graphics. Developed by the team who brought you "Rainy Days".
To show them like in the original Crysis we have to write a special code for each of the sentences with the description of all sound effects that should put on the dialogue. For example there are typical radio or background effects like weapons and explosions.
So he wrote this programm where you could select the speaker character, the volume of the voice and it's effects.
The "background fading" controls how quiet all other sounds will be if this dialogue is spoken and the "character function" controls the colour of the subtile.
