Ian has been a professional sound designer for nearly 20 years, the purpose of sound design is to either ehance what’s there, so flapping jackets about to get the sound for a flag or sampled and slowed down for birds etc etc, to recording the beep of
a checkout till while the checkout chick looks at me very suspiciously while i’m stood there holding a microphone and DAT recorder. Or create a sound for something that doesn’t exist such as for a cockroach, tiny pattering feet and very high pitched clicky sounds. or a cave of ants partying in their underground sports bar beneath the football pitch where the world cup is taking place. Very often it’s multiple layers of sounds, pitched and filtered in such a way so that it becomes ONE believable sound that’s on the screen.
