AltiSpace is a convolution reverb app with advanced controls that provides realistic sounding natural acoustic space or the most famous reverb devices for any track or mix. A convolution reverb takes a captured sample (called an impulse response) from a real-world space or hardware and uses this to digitally simulate the reverberation of that space or device down to the last detail and nuance. Because it is sampled, not synthesized, convolution reverb is known for its stunning realism, and it is widely considered to be the best type of reverb. However, unlike the more common algorithmic reverbs, convolution reverbs usually does not have much control over the reverberation process. But AltiSpace, in addition to the ability to load your own impulse response files and a built-in library of real reverb device presets, has advanced settings such as EQ, gate, ducking, modulation and more. You can change the original impulse response parameters to something completely new and then save it as a new preset. This app has an easy-to-use user interface, where all the main controls are located on the single screen, and it is ready to use right out of the box, even without additional settings. And at the same time, you can easily change the parameters of the impulse responses from the built-in library to create your own sound. App features: Ability to import your own impulse response files. A large built-in library of presets from the most famous hardware reverbs. Convenient preset manager with the ability to group and search presets. Presets can be marked as favorites for display in the favorites group. Supports MIDI controllers (also Bluetooth) with learn or manually assign mode. Reverb can work with a stereo or mono input and convert it to stereo. Add dynamic noise before reverb for a more natural sound. The gate allows you to turn on the reverb when the threshold is exceeded. The ducking allows you to turn off the reverb when the threshold is exceeded. Sets the minimum reverb level for Gate and Ducking modes. Equalizer with high and low cut filters in chain before or after reverb. Changing the time (length) of the current impulse response. Possibility to set a fade out point for a smooth end of the impulse response. Sets the pre-delay time of the signal before reverb. Experimental feature to change the pitch of the impulse response. Amplifying early or late reflections. Adjusts the stereo image before the reverb. Haas effect for adding stereo space to a mono signal. Sets the depth and frequency of modulation the signal before reverb. Mixing dry / wet signal and adjusting the output level. Four-channel mode for better stereo ambience. Input and output level meters. Indicators of possible input clipping for standalone. Prevents any output clipping for standalone. Built-in full description of all controls.

About

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.

Highlights
  • 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 call

The clearest difference is update cadence: AltiSpace 2 at monthly against Replicant 3's every 18 months. AltiSpace 2 also leads on chart position (#138 vs unranked) and review sentiment (78% vs 67%). Replicant 3's advantage is price ($4.99 vs $7.99). On ads, in-app purchases, monetization model and iOS requirement there is nothing between them.
