In any Hollywood blockbuster there’ll be layer upon layer of sound effects ranging from huge explosions to tiny footsteps and they all help add to the magic of cinema. When you’re creating your own personal movies, making use of different sound effects is a great way to make them much more professional. GarageBand has some great built-in effects, but making your own from other sources can be a great remedy to sounding like everyone else. There’s a lot of trial and error involved, but we’ve got a few handy tips to make the whole process a lot easier. Once you’ve mastered the techniques in this tutorial you can use the process to make changes to imported sounds and loops and create your very own library of cool effects for future iMovie projects. A few hours spent creating sounds will certainly pay dividends.
