squaresweep4-labchirp.wav
Both operators were set to "Square". This sound is mostly common in soundfonts as the "square lead" preset, and has this electrical sci-fi esque mystical sound in the background as a depth effect. As with the other sweep sounds from me created using LabChirp, this sound consists of two operators at either the same or different frequencies. Operator 1 is always set to 57.7 in frequency, while Operator 2 is set to 57.8.
Created using LabChirp, a program that simulates a 6-operator additive synthesis technology.
