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.

Circa runs as a standalone app, or as an AUv3 plugin in hosts such as GarageBand, Logic, AUM and Cubase. Equal parts workhorse and abstract creative tool, Circa is a six track multi-layer looping environment that can do most of the things your popular floor pedal looper can while also paying homage to the serendipitous world of ambient looping. Each layer can sync to the host, a master loop, or free run, and can be triggered in sync, with an audio signal, or freely. Circa has seven stereo outputs (including a dedicated cue output for monitoring) and built-in reverb and delay. Add in a complete MIDI control and LFO modulation system and Circa is a full looping workstation. Features -- Multi-Layered Looping Circa has six layers that can operate independently or in sync with each other and/or the host. Circa can record from the stereo input, or self-record via an internal buss for interesting feedback possibilities. -- Standalone Or Plugin As a standalone app, Circa has its own audio and MIDI settings: choose your audio interface, sample rate and buffer size, pick the input pair, send each of Circa's seven outputs to any output pair on your interface, and select a MIDI input. Sync to incoming MIDI clock, or let Circa set the tempo from your first loop. As an AUv3 plugin, it lives inside your host and syncs to its transport. -- Designed To Be Touched And Played Circa's user interface is made for tactile manipulation, with touch strips for speed and position (including dedicated pages). The position strip can be further subdivided with slices. All this works together to turn a looping effect into a playable instrument. -- Easy To Get Along With Circa's layers each have an undo for destructive edits like recording, overdubbing, and erasing. -- Controllability And Modulation Circa has 30 modulation slots. Each one can map a MIDI controller to any of Circa's looping functions, or run an LFO: seven shapes, free-running or tempo-synced, with rate, phase and level, modulating speed, start and end position, level, panning, delay and reverb sends, filter frequency and resonance, or the slice the play head is on. LFOs swing around wherever each control is set, so the knobs stay in charge. -- Self-Contained Circa has a full internal mixer, filtering on each layer, and studio-quality send reverb, send delay, parametric EQ and compressor taken directly from Audio Damage's extensive effect library. -- Expandable And Performance-Ready Circa has 7 outputs in all: six assignable stereo outputs and a cue output for monitoring. Send any layer to any of the six stereo outputs, while keeping the cue for soloing, recording, and editing, unheard by the audience. In the standalone app, each output can go to its own pair of outputs on your audio interface. -- Ecosystem-Aware Circa's user presets are cross-platform compatible, and work on any instance of Circa, whether on macOS, Windows, Linux, or iOS. In addition, sessions created in GarageBand or Logic on iOS will open in the desktop version on macOS if you have purchased a license to that version.
