1. How you think the sound in your chosen example has been produced (production techniques)
I believe the soundtrack was produced by using Live audio recording of a live orchestra. The orchestra is predominantly the violin but other instruments are included too.
The sounds that are made when, for example, the player jumps on a tiled roof. These sounds are recorded as are all the environmental sounds that are used in this game footage. Whereas the voices of the civilians and guards in this clip are studio recorded by real people just saying the script which is assigned to a civilian in the game.
2. What post-production techniques have been used to create the soundtrack (using subject specific terminology)
I believe that the soundtrack has used a mixer to combine the live environmental audio recordings and the voice recordings. The most predominant effect used is an air effect that features to give the effect that the live audio recordings are outside and when the player jumps on to the rooftop the wind sound increases slightly.
3. How the sound design of your chosen examples might enhance the gaming experience for audiences.
This Soundtrack is soft and melodised which complements the sneaky mischievous content which the player has to do. This is used as they would in the movie industry to emphasise a note of mischievousness within the viewer while playing/watching.
When player is engaged in a fight or in some form of combat then the music volume and intensity increases to give the player an adrenalin rush as you would in a real situation.
