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
Replicant 3
This real-time audio effect processor captures, loops, and mangles audio on the fly. It offers advanced sequencing with per-step probability and direction, alongside four distinct slice effects for creative sound design. Control dynamics with envelope crossfading and trigger slices manually or via MIDI.
- Real-time audio slicing and mangling
- Advanced step sequencer (3-16 steps)
- Four distinct slice effects (Stutter, Delay, Redukt, Ring Mod)
- Envelope crossfading for dynamic control
- Manual and MIDI triggering
- Intuitive visual step sequencer interface
- AUv3 compatible

Replicant 3 is a real-time audio slicing and mangling effect, the third generation of the plugin that started the genre in 2007. Feed it any audio and Replicant's sequencer captures, loops, reverses, and re-slices it on the fly, layering in delay, filtering, panning, ring modulation, and bit-crushing to turn predictable tracks into something unpredictable. Version 3 is a ground-up rebuild with an all-new sequencer engine, expanded effects, and a redesigned interface that makes programming complex slice patterns fast and intuitive. SEQUENCER ENGINE Program 3 to 16 steps per measure with multiple step-size modes, from dotted notes through nontuplets. Build rhythmic patterns that go well beyond straight time. Per-step probability, direction (forward or reverse), and effect routing let you create patterns that evolve and surprise. FOUR SLICE EFFECTS The original Stutter capture-and-repeat is joined by three new modes. Delay adds rhythmic echoes to sliced audio. Redukt applies bit-crushing and sample-rate reduction for lo-fi destruction. Ring Mod adds metallic, inharmonic tonal coloring to any slice event. ENVELOPE CROSSFADING Smooth transitions or hard-gated rhythmic chops on every slice event. Control the attack and release shape of each captured buffer for precise dynamic control. MANUAL AND MIDI TRIGGER Bypass the sequencer entirely and fire slices on demand. Manual trigger mode works with touchscreens for live performance. MIDI trigger lets you drive Replicant from a controller, keyboard, or DAW automation. REDESIGNED INTERFACE A visual step sequencer puts your entire pattern on screen at once. Edit steps, assign effects, set probabilities, and adjust parameters without menu-diving. CROSS-PLATFORM PRESETS XML-based preset manager with presets compatible across all Audio Damage plugin formats and operating systems. SOUND DESIGN IDEAS Sequence stuttering vocal chops with per-step filter sweeps. Build glitched-out drum fills by randomizing slice direction and bit-crushing depth. Layer ring modulation on sustained pads for metallic, evolving textures. Use MIDI trigger mode to fire slices manually in a live set. Program polyrhythmic slice patterns with odd step counts against 4/4 time. Run full mixes through Replicant on a bus for controlled chaos breakdowns. AUv3 compatible. Runs standalone or hosted in AUM, ApeMatrix, Audiobus, Cubasis, GarageBand, and other AUv3 hosts on iOS 11 or newer. From Audio Damage, making creative software for discerning musicians since 2002.

Verdict
The clearest difference is rating: Gauss Field Looper at 4.7 against Replicant 3's 4.0. Gauss Field Looper also leads on update cadence (every 4 months vs every 18 months) and ratings volume (115 vs 4). Replicant 3's advantage is price ($4.99 vs $6.99). On ads, in-app purchases, monetization model and iOS requirement there is nothing between them.
