BeatCutter is a playground for anyone who loves experimenting with sound. It’s an innovative multi-channel tool that slices, reshapes, and recombines audio based on rhythm, letting you build evolving textures, chaotic patterns, and completely unexpected musical structures. At the heart of the app is a flexible matrix of sample cells with fluid routing for recording, playback, and control. Whether you’re working with long audio files, live instruments, or sound from other apps, BeatCutter turns any source into raw material for creative exploration. Craft immersive sound worlds With BeatCutter, you can sculpt everything from cyberpunk atmospheres and industrial drones to alien jungles and meditative soundscapes. The type of source audio doesn’t matter - the magic comes from how you transform it. Your settings and your imagination define the final result, which can range from futuristic IDM to abstract ambient textures. Designed for experimentation BeatCutter doesn’t rely on fixed presets. Instead, it gives you a powerful set of parameters that encourage hands‑on discovery. To help you get started, the app includes a template editor where each number represents a group of settings. Tweak the numbers, listen, randomize, refine, and save your favorite states as presets. Explore evolving sonic feedback One of BeatCutter’s most unique features is its experimental feedback mode. This isn’t traditional analog feedback - it behaves more like a living fractal, constantly reshaping itself. The result is a self-evolving sound structure capable of generating rich, abstract audio without any external input. It’s a perfect tool for deep experimentation and unexpected inspiration. BeatCutter is for artists, sound designers, and curious creators who want to push beyond the ordinary and discover new sonic territories. BeatCutter 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). BeatCutter works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On MacOS, BeatCutter can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. All application features are available on iOS and macOS, including MIDI support (with a MIDI learn option) and audio unit parameters. BeatCutter has a built-in detailed description of all parameters also available as PDF file on the application site.
