Music and Sound effects

For my trailer, when finding music , I used certain effects from iMovie, and builded upon these sound effects to create more of a suspenseful sound. At first I choose one sound track to use for the first part of the trailer, however I then added other more dramatic effects, at the parts in the trailer, as seen in the screenshot










After the introduction of the trailer, I used a 'thunder clap' sound effect, to set a dark atmosphere. by adding a black screen background at this point also shows the audience that something else is about to happen, making them feel like they she continue watching, as they would be drawn in by the first few shots of Spencer. 

Throughout my whole trailer, I decided to add one piece of music, which I found from a channel on YouTube. I picked this music because it fitted in perfectly with my trailer, as they music started of soft and calm, and the atmosphere built up gradually, the same way the excitement in the trailer grows. I added a second piece of music, but cropped it down, to use only where I wanted extra suspense and tension to be created.
For my voiceovers, I used a professional microphone to record the voiceovers to add in certain parts of the trailer. When I planned the voiceover, I wanted them to be very confusing but to add tension too, which is seen in the trailer.
When adding the voiceovers to my trailer, I lowered the music in the background, so that the voice is heard clearly. I left the music running in the background as a settling effect.
