These are some videos I found interesting as part of my research into Sound Design.
Caoimhe Doyle of Ardmore Studios who has also worked on Game Of Thrones shows Newstalk's award winning science show Futureproof how to make sound effects for movies
Ben Burtt talks about creating the sounds for the lightsabers in Star Wars. As he worked on "A New Hope", Burtt probably wasn't aware that he was inventing modern sound design.
