to keep the dynamics of a softer sound, but dampen the louder sounds, the side chain would effect the threshold knob instead of the gain knob. If the bass was more dynamic, and included quieter elements, along with louder elements, that worked with the kick, then a more typical compression would be used. This means no matter how loud the bass is, it’s signal will be lowered by the kick drum. This form of compression applied to the bass synth is constant across it’s audio level, unlike most compression. Listening to the bass, you can hear how the sound seems to pulse with the kick, when usually the bass line would sound like a constant tone. On the right side of the compressor, you can see the gain knob ducking in sync with the kick hitting. Below is the compressor, affecting the bass synth. In the preview above, the top module is listening to the kick drum, displaying it’s volume over time. Sidechain compression in Length of a Moment (Feat.
When the kick drum hits, the compression starts, and the affected bass synth is dampened, allowing the kick to sound large and full of bass. In my mix, the input is almost always the kick drum. The input sound decides how much compression will be applied to the affected sound. Sidechain compression takes one sound as an input and one sound as the effector. In this album, all bass heavy synths have sidechain compression applied, to let the drums push through the mix. Overall, sounds are all filtered through the master limiting compressor, but individual elements are first affected by their own compression. Sidechain Compression in the Dreaming City This shifts all sounds into a loudness zone, where nothing goes quieter than the threshold and nothing louder than the ceiling. The other parameter is the “Threshold”, which enables gain compensation to boost sound that is quieter than the specified level. The limiting compressor used in the song Length of a Moment (Feat. The goal is to compress the sound so it’s not to go louder than the ceiling. Everything past that level is heavily compressed, and is said to be “Limited”. With a Limiting Compressor, sound begins compressing if the volume reaches a certain level, called the “Ceiling”. Two pieces of music or sound may mesh when their notes are in the same key, but also when their effected by processing in the same way. These sounds aren’t necessarily cohesive when played together, but when pushed through the same compressors, the sounds begin to mesh. Songs throughout the Dreaming City contain many samples, ambient noises and trippy reverberations. Taking inspiration from electronic music group Justice, compression is the glue of the album. Compression is used heavily throughout the Dreaming City album.
