Professional Granular Synthesis for Dark Ambient Soundscapes
Occult Audio Engine is a granular synthesis application for creating evolving pads, drones, and ambient textures. It transforms audio samples into continuous soundscapes.
The library includes:
•Troath singing: deep and dark troath singing records
•Chants layers: layered vocal textures for depth and brightness, as well melody modulations instead of static drones
•Instruments layers: bowed strings, jaw harps, horns, bells, rattles and didgeridoo
•Miscellaneous: experimental and atmospheric elements divided into low freq drones and mid-hight freq textures
In addiction, you can load your own samples into any of the three layers to build complex, evolving textures.
Three independent layers, each with:
•Independent sample loading: load different samples per layer
•Granular synthesis controls: grain size, overlap, stretch, rate, and pitch
•Layer-specific filters: per-layer cutoff and resonance
•Saturation: adjustable warmth and harmonic enhancement
•Independent dry/wet reverb control: blend dry and wet per layer
•Stereo width: per-layer panning control
•Reverse playback: per-layer direction control
Layer samples together to create dense, evolving textures. Each layer can use different samples, parameters, and effects.
Advanced Grain Processing
•Window functions: Harmonic (smooth exponential) and Blackman (spectral shaping)
•High overlap (90%+): seamless blending
•Organic variation: subtle jitter, timing drift, micro-pitch, and grain size variation to reduce repetitive patterns
•Seamless looping: buffer wrapping for continuous playback
