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.

IMPORTANT: Circa is an AUv3 plugin. It requires an AUv3 host such as AUM (recommended), Garageband, Logic, or Cubase. It will not run on its own. Circa is a six-layer stereo looping instrument for iPad, built for players and producers who want a looper that does more than loop. Each layer is independent, fully modulatable, and deeply controllable, with a touch-first interface designed for live performance and studio exploration alike.Inspired by modern loopers like the BOSS RC-505 and MLRE on the Monome Norns, Circa pairs the playability of a hardware looper with the routing and modulation of a serious production tool. Capture a spontaneous take, carve it up with slices, pitch it, scrub it, route it through built-in effects, and let gesture recorders play your UI back like a second instrument. SIX LAYERS Six independent stereo loop layers, each with its own transport, sync mode, trigger mode, filter, and effect sends. Layers can sync to the host, sync to a master loop, or run free. Triggers can fire on sync, on audio input, or freely. Record from the stereo input or self-record through an internal buss for feedback loops and generative behavior. TOUCH-FIRST PERFORMANCE Dedicated pages for Speeds and Positions let you perform loops with your hands. The position strip can be divided into slices for chopped playback. Speed, position, filter, and sends are all continuous and playable. Damper, scrub, and slice controls are built for tactile manipulation, not mouse input. GESTURE RECORDERS Six UI loopers that record and play back your actual control movements. Almost every parameter in Circa can be captured as a gesture, then looped or played as a one-shot. Trim silence from the front, toggle loop mode, or fire gestures from MIDI. Build evolving performances without touching the interface twice. MODULATION Deep modulation across the plugin. Continuous targets include layer delay and reverb sends, output levels, A/B selectors, play position, and more. Momentary targets cover mute, solo, and toggle states. Assign multiple modulators to any target and build performances that develop on their own. FULL MIDI CONTROL A complete MIDI controller system with continuous, momentary, and hold assignments. Use any controller to drive most of Circa's functions. MIDI modulation assignments light up briefly when triggered, so you can see your rig working at a glance. BUILT-IN EFFECTS Studio-grade reverb, delay, parametric EQ, and compressor drawn from Audio Damage's effect library. Send any layer to reverb and delay independently, then route through the stereo bus EQ and compressor on the way out. SEVEN OUTPUTS Six assignable stereo outputs plus a dedicated cue output. Send any layer to any output. Solo, record, and edit through the cue bus without the audience hearing. CROSS-PLATFORM PRESETS Circa's user presets are XML-based and cross-platform. A preset made on iOS opens on macOS, Windows, or Linux, and vice versa. Sessions built in GarageBand or Logic on iOS open on desktop if you have a license to the desktop version. WHAT'S INCLUDED Six independent stereo loop layers Slice-based position playback Gesture recorders for UI automation Continuous and momentary modulation system Full MIDI controller mapping Built-in reverb, delay, EQ, and compressor Six assignable stereo outputs plus cue Cross-platform XML preset format AUv3 plugin for iPad Also available as a desktop plugin for macOS, Windows, and Linux in VST3, AU, AAX, and CLAP formats at audiodamage.com.
