Read full description

NoiseSpace is an experimental sound generator based on simplex noise, which is then used in a granular synthesis algorithm. This design allows for the creation of a vast array of diverse waveforms rich in harmonics with a rich low-frequency spectrum. The generator is controlled by just a few simple parameters. Despite its somewhat chaotic and atonal nature, it is great for creating rich noise, gritty textures, complex patterns and deep, dark, mesmerizing and tense backgrounds. It is especially suitable for creating ambient compositions, as well as sci-fi, industrial, post-apocalyptic and horror atmospheres. This app also serves as a powerful tool for noise art and sound design, offering users the ability to craft intricate and captivating sonic structures. With its focus on deep, hypnotic, and tension-filled soundscapes, NoiseSpace is an essential tool for musicians, sound designers, and artists exploring experimental and textural audio creation. Starting with NoiseSpace is remarkably easy. The application features a dedicated "Create" button that generates unique and interesting presets ready for immediate use, requiring only minimal adjustment to suit the user's needs or ideas. Additionally, it includes options for generating sequences and patterns, and for simple tone and modulation creation for each generator, making the application user-friendly and ready for immediate exploration right from the start. Key Features: Five Sound Generators: Utilizes simplex noise and granular synthesis to create diverse sound textures. Versatile Sound Options: Offers a vast range of sound variations with just a few parameters. Advanced Filters: Includes both classic and complex filters for each generator. Low-Frequency Modulators: Each generator is equipped with three LFOs that can control most parameters. Dual Output System: Each generator has a main output and a special output for background sound. Layered Sound Design: Generator outputs are combined to create two layers - main sound and background. Pattern and Texture Creation: Features an internal sequencer / binary counter for managing generators. NoiseSpace is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). NoiseSpace works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On MacOS, NoiseSpace can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. NoiseSpace has a built-in detailed description of all parameters also available as PDF file on the application site.

GRFX is a powerful and creative granular effects processor that turns ordinary audio into extraordinary sonic landscapes. Slice your sound into grains and reshape them into evolving textures, shimmering chords, rhythmic glitches, haunting drones, and more. At the heart of GRFX is the Harmonic Triangle – an intuitive 3-way pitch controller that lets you morph simple tones into lush pads, arpeggiated patterns, or abstract gestures. Whether you’re aiming for organic soundscapes or synchronized stutters, GRFX gives you precise control over the flow of grains and modulation. Build complexity with four self-modulating LFOs, a multi-effect chain with probabilistic routing, and an elegant drag-and-drop modulation system. Shape your sound, modulate nearly every parameter, and sculpt immersive audio transformations in real time. Key Features: - Granular engine for creating textures, rhythms, chords, glitches, drones, ambiences, and more - Harmonic Triangle for 3-way pitch control, detuning, and microtonality - Built-in Chord Selector with 32 triads for instant harmonic richness - Grain envelope shaping for plucky, smooth, or abrupt grains - Buffer size, division, sync, and freeze controls - Rhythmic synchronization for tempo-synced effects and patterns - 4 LFOs with self-modulation and drag-and-drop assignment - Modulation panel & view mode for streamlined modulation management - 2 Multi-Effect slots (Filter, Distortion, Delay, Peak EQ, Chorus, Phaser, Bitcrusher, Reverb) with probability-based routing - Dedicated Send FX with Delay and Reverb in series or parallel mode - Flexible mixer section for sculpting wet/dry balance and routing AUv3 Audio Unit plugin – requires an AUv3-compatible host app such as Logic Pro, GarageBand, AUM, or Cubasis. Standalone version included.
