Co-designed with Berlin-based electronic musician Hainbach, Gauss brings the oldschool tape-looping art form to mobile devices. This creative field looper works both standalone and as an Audio Unit effect plugin and puts the possibilities of using looped tapes in your hands. Without the need for scissors. Like real tape loops Gauss takes you off the grid of your DAW: you can adjust tape speed and direction, even during recording. The flow of your loops will drift organically as the tape follows its own cyclical timeline.  Use overdub, or even multiple instances of the Audio Unit plugin, to create multi-layered ever changing sonic palettes. We want this app to be a celebration of digital audio technology, so when audio quality is degraded it will do so in a pleasingly crunchy digital way. For example, recording on low tape speeds will give you longer recording time, but at the cost (or pleasure) of a distinctively lower recording quality. So Gauss mimics the behaviour - not the sound - of magnetic tape. Set the length of the tape, record and overdub your audio, play around with tape speeds; Gauss captures the essence of two ends of tape stuck together in all its unsynchronised, free-running glory. There's even a unique built-in 4-step polyrhythmic sequencer for sequencing tape-speed changes. - designed as a standalone field recorder and an Audio Unit effect plugin (AUv3) in one package - universal app: plugin and standalone work on all iDevices, iOS11 and higher - variable tape speed; seamlessly change direction and speed during playback or recording - 4-step sequencer lets you trigger (polyrhythmic) tape-speed changes in sync with your host tempo - variable inertia for the tape drive motors (from instant to very slow speed changes) - built-in multi-mode filter with LFO modulation - delay effect with optional host-sync mode - “1989” mode uses a special 8 bit/11KHz tape head for a last-century vintage digital sound - 45 seconds maximum loop size at 1x speed, proportionally longer at lower speeds (.e.g 90 seconds at half speed, etc.) - overdub at any speed or tape direction - plugin supports global cross-host preset handling (requires iOS13+, compatible AUv3 host) Find the user manual at ruismaker.com

Read full description

Loop-based mangler effect to create slowly changing rhythmic sound structures in deep reverb space from any external sources or samples. Great for experimenting and designing ambient and noise backgrounds with rhythmic elements. The principle of the application is quite simple. It is based on a loop recorder with two loops. When one loop is recorded, the second is played back. When the loop recording stops, there is a smooth transition between them. Three separate outputs can playback the recorded loop with different pitches (speeds), each with its own effects and two automation generators. The mix of these outputs is fed to the convolution reverb. The reverb is packed with a set of long and deep sound spaces that create a blurry and ambient sound. But the main feature of this application is its well designed parameters that make it easy to experiment with a huge number of sound options using any source material from live instruments to synthesized sound. With just two parameters you can add complex rhythmic structures based on Euclidean rhythms, and easy-to-use automation generators with a randomize option to add variations to the sound, allowing you to modify parameters like an LFO or based on a given rhythm. The convolution reverb has advanced options with which you can change and extend the original reverb spaces. Even using the randomization options, in almost every case, you will get interesting and various soundscapes and textures. With these options it is very easy to create the basis for new unique presets. It only takes a little tweaking of some parameters to get impressive results. The loop recorder can be started and stopped manually or by input signal, can use fixed length or overwrite the loop while recording, and has the option for crossfade between the end and the beginning of the loop. All this makes it convenient for live use as well as when processing recorded material. As an extended option, you can use a special mode in which the application works as a direct effect, without the loop recorder. The special mode sampler is designed for quickly load samples and easy control of the application when used it live. This panel contains the input and output controls, essential controls of the loop recorder, and a large area with a recording counter, which is also used to start/stop the recorder. You can assign up to nine samples for fast loading into the loop, as well as save a recorded loop as a sample and to an external file. SpaceFields 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). SpaceFields works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, with supports Audiobus host app. On MacOS, SpaceFields 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), audio unit parameters and importing samples from any directory on device. SpaceFields has a built-in detailed description of all parameters also available as PDF file on the application site.
