HollowTone vs FIELD KIT Playback Engine

HollowTone is a place to explore sound as atmosphere - a quiet world of shifting textures, deep pulses, fluid motion, digital flicker, and soft human-shaped warmth. It isn't a traditional synthesizer or a simple ambient player. It's a procedural audio instrument that lets you shape entire environments with just a few gestures, creating spaces that feel alive, mysterious, and gently immersive. Each layer inside HollowTone behaves like its own living entity, generated entirely in real time without samples. Blend them together and new forms emerge: fog-like air, cavernous resonance, flowing noise, glitchy sparks, or distant vocal presence. These sound worlds work beautifully as meditative backgrounds, relaxation environments, dreamlike spaces, or darker atmospheres for games, videos, and creative projects. Despite the complexity beneath the surface, HollowTone is easy to navigate. The nine macro parameters let you shift the entire soundscape with subtle, expressive control, while the built-in randomizer offers quick ways to discover new ideas - from gentle variations to completely unexpected worlds. Whether you're seeking calm, tension, inspiration, or a place to wander, HollowTone invites you to explore sound intuitively. No rules, no fixed paths - just a quiet landscape waiting to be shaped. HollowTone is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac M1 and later. HollowTone works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On MacOS, HollowTone can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. HollowTone has a built-in detailed description of all parameters also available as PDF file on the application site.

FIELD KIT is an audio playback instrument built for turning recorded sound into evolving texture, rhythm, and atmosphere. Load an audio file and create up to four independent playback windows across the recording. Each window can move through a different section of the source with its own playback speed, direction, crossfade, drive, filtering, level, and pan. Use FIELD KIT to pull overlapping textures from long field recordings, transform environmental sound into ambient beds, create asynchronous loops, or find entirely new material hidden inside a recording. Three modulation sources can be routed independently across the playback windows, allowing parameters to drift, pulse, and evolve over time. Features include: - Up to four independent playback windows - Forward, reverse, and ping-pong playback - Variable playback speed - Adjustable loop crossfade - Drive and filtering per window - Independent level and pan controls - Three routable modulation sources - SPLICE for working with multiple audio sources - Save and recall .fieldkit files to share across platforms - Internal recording in Standalone mode - Standalone app and AUv3 Audio Unit - Host transport support in compatible AUv3 hosts FIELD KIT was designed around a simple idea: a recording doesn't have to be played from beginning to end. It can be a place to explore.
