Dark Curse

How it's made

Source

a ritual spell in three layers. A reversed swell (dark noise whose band opens and level grows until it is cut at the moment of casting), a cluster of dissonant bowed-like tones, and a sub-bass heartbeat.

Body

the tone cluster is a root, a minor-second partner (beating at 5-15 Hz) and a tritone partner, built from saw and triangle oscillators under a low-pass that closes from 2.4 kHz to 400 Hz while the pitch sinks by an octave. The throb is a 48-70 Hz sine with a faint 2nd harmonic, gently saturated so that it reads on small speakers; a slow vibrato makes the cluster waver.

Envelope

the swell rises over the first ~40% of the length on an exponential ramp and drops in ~15 ms (the reverse of a decay). Tones start at the cast, fall in pitch on an exponential curve and fade out. The throb pulses at about 2.5 Hz with a slow decay and ends with the tones.

Variation

`rng` shifts tuning by up to 1%, the vibrato phase and the noise streams; macros set length, pitch, dissonance, darkness and throb weight; presets range from a quick hex to a long, heavy doom.
