## What is AltiSpace 2?

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.

### 5/5 — Parfait

*2026-06-18*

J’ai trouvé ma reverb.
Large catalogue d’IR de mythiques reverbs avec un bel historique fourni.
Suffit de charger et ça sonne.

### 5/5 — Fantastic IR Based Reverb

*2025-12-25*

Standalone or as plugin. Only downside is that the UI is really small on iPhone.

### 4/5 — Love it but it disappeared?

*2025-11-18*

As of last week this app will not show up any more…. I can’t even find it…. I uninstall it and reinstalled it but still nothing…. Please fix.

### 2/5 — Confused

*2024-07-01*

Using Logic Pro for iPad it seems as though the app just doesn’t seem to work? Tried dropping it into audio and midi tracks as well as thru various sends and it just mutes the audio??

### 1/5 — Bad color choice

*2024-06-14*

this is hands down the badest color choice ive ever seen for a plugin. 
on a iphone its almost not useable. 
second, strange convolution engine where you can't change the ir lenght. 
strange concept.

### 3/5 — Logic pro send fx bug

*2024-04-04*

Does not work in logic pro (ipad) as send effect via bus. Effect just mutes the output. I fixed this by toggling the project from 48k to 44k then back to 48k. Bug??  It worked as an insert fx right away @ 48khz but not as a send until I messed with the project sample rate in logic pro. I discovered this fix through the previous change log that detailed another 48k fix, related?  Logic pro ipad defaults to 48khz projects.

Otherwise this is a great sounding plugin (but I don’t like the GUI !).

### 5/5 — Just WOW!

*2024-02-10*

IMO, the Holy Grail of reverbs… This app offers SO much at an unbelievable price! I’ve compared it to a handful of others and am blown away by this one! Just WOW! Thanks! (Note to Dev: I made my decision to look into this app after watching Doug Woods’ review from 2 hrs ago. -It takes me a while to watch all his reviews…😉😆) Keep up the great work! ✌🏻😎🎹🌴🌞

### 4/5 — Sounds great

*2023-08-05*

But the User Interface is not good

### 4/5 — Great tweakable IR reverb. UI is teeny tiny on iPhone tho

*2023-03-03, version 1.4*

If only the text was bigger on iPhone!

### 5/5 — A world of spaces

*2022-12-09*

This app’s presets emulate those of classic reverb devices from the late 70s onward rather than directly sampled identified locations (so far as I can tell). The developer’s site, however, links to free downloads of professionally sampled impulses from Britain and elsewhere. I loaded York Minster, a 10-second sample of this largest of medieval cathedrals created by firing a starter pistol. I found it necessary to smooth out the onset by importing the .wav file into audacity and deleting a few milliseconds of silence prior to the shot. The end result sounds amazing in AltiSpace. The parameters offered to nuance the effect are thoughtfully implemented.
