Trope, designed by ambient pioneer Brian Eno and musician / software designer Peter Chilvers, expands further on the ideas introduced by Bloom, their acclaimed iPhone application. Darker in tone, Trope immerses users in endlessly evolving soundscapes created by tracing abstract shapes onto the screen, varying the tone with each movement. Recommended for headphones and external speakers. "Trope is a different emotional experience from Bloom - more introspective, more atmospheric. It shows that generative music, as one of the newest forms of sonema, can draw on a broad palette of moods." - Brian Eno

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.
