I started by importing an MP4 of the final scene of the film and dragging it into Ableton. I decided to use the field recording of the tumble dryer and reverse it. I found reversing it, and then transposing it down, added a layer of creepiness and discomfort. The field recording runs through the entire track, which I feel gives it a building tension as it carries on as the track gets busier.
Midway through the piece, as the scene continues to get tenser, I decided to add an 808 kick pattern. I did this to add more tension as it slowly speeds up and then goes back to its original speed, which creates more anxiety in the viewer. The kick is mixed quieter than most of the track but can still be heard, not overwhelming the rest of the sounds and acting as a heartbeat underscoring the piece.
At the same point as the 808 started, I used an Ableton synth from their Drone Lab pack called Parsec Breach. What I like about Parsec Breach is that it is a synth drone, but instead of being a low synth it has screeching highs that fit well in a horror movie. If the whole piece is just a low droning note it can get muddy and boring. It is important to explore all the pitch and frequency ranges you can to make the piece more interesting and dynamic. I mixed Parsec Breach so it gradually gets louder throughout the scene, so it gets more intense until it is unbearably loud.
Near the end of the scene I used a machine ambience I found on Ableton. I thought this sounded interesting and industrial which was exactly what I was looking for. I used an Ableton plug in called Drone Maker which transforms any sounds into a Drone. This gave the sound more ambience.
