We decided to stick with our original sound. we used the pen tool to adjust the volume so that we could bring ti in and out. We found while watching back our thrille rthat the sound began to feel repetitive and we don't want the audience losing intrest now would we?!.
So our best solution was to make some of the sound low in volume and some high and keep a nice level and mixture of sound throughout. We only made slight changes, as we didn't wasn't the sound to seem messy and out of place. It fits in well with our opening and we hope that the audience enjoy it as much as we do :)
