Sibilla is a DSP digital stereo oscillator that aims to translate into music the beauty and harshness of a semi-barren mountain. Its sound is sculpted by various sawtooth and sine waves running through intricate delay networks, altered by LFOs and white noise, creating constructive and destructive interferences.

Both stereo channels are the output stages of two feedback audio loops.

Each loop consists of a main sub-sinusoidal wave oscillator and two sawtooth and sine waves with frequencies affected by the generation of harmonics (right channel) and subharmonics (left channel). All waves have different phases whose offset is constantly influenced by minor variations created by two pairs of grains randomly fluctuating within the wave amplitude spectrum and sampled at a certain speed.

Waves then converge at a common point, along with two white noise sources, creating constructive and destructive interferences constantly influenced by two LFO movements.

Interferences are then passed through a resonant low-pass filter and distributed to four different delay lines, from which they are fed back into the audio loops at different time intervals depending on the grains' movements.
