This by far has been the best project in Audio Arts to date, well at least for me it has. Although towards the end i was a bit over the Asset creation and tired of constantly coming up with new ideas, the process is still interesting. Actually playing the game with your sounds is the best part of the whole project. Testing to see if it is actually 'believable' for the game, trying to make them better than the original sounds. My favourite sound was one of the easiest ones to make. This was the weapon change sound. It was a recording of stuffing things into a bag and it sounded just like many other FPS weapon swap sounds, and i think it was better than the original 'swoosh' sound. This is certainly a field I'll think about experimenting with in the future.
