AltiSpace 2

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.

This app has such an amazing algorithm that it isn’t just reverb. Of course, it’s “convolution” reverb, and the description given by the developer is as good as any. Beyond that, this is the layman’s version: This thing can take synth sounds and insert this “convolution” -into- them, almost as though it occupies your preexisting sound. This can be attenuated, so it’s not out of control. This alone is what makes AltiSpace a synthesizer in and of itself and why I think it deserves more recognition on iOS. The recently added iOS optimization is a huge deal for how powerful this thing is. I’ve never experienced any kind of crashing with this thing, even though reverbs tend to have complex algorithms that lend to CPU hogging and therefore crashing. I’ve only scratched the surface of what this thing can do. But the combination of SynthMaster 2 and AltiSpace alone can replace Jerry-rigging a bunch of apps together to try and achieve the same effect. It’s an FX machine just as much as it is a “space machine”. Slap five stars on it 👍🏻

EXACTLY what I was looking for! It sounds amazing, is easy to use, comes with a ton of impulses, is very easy to load your own wav file impulse responses, and is light on CPU on my iPad Air 4. Browsing patches is also very organized. I HIGHLY recommend this. It’s super fun to use on drums or just about anything else. Can make reverb type sounds, delay type sounds, and even phaser or flanger, but can get weirder and more interesting than any of those plain effects alone. It also can add interesting reflections and some harmonics if used with the right IR files, try one captured from a metal can or a grain silo. :) There are also controls for shaping the sound that other convolvers don’t have. Combine this with a saturator and you can really get into some sound design fun. I’m using it for ambient, dark ambient, industrial, techno, industrial metal, horror soundtracks and experimental electronic, but it’s super useful for many genres. Check out convolution sound design, you can do a lot with your own impulse files, but this app is also really complete if you only use the built in impulses. Kudos to the developer. I’m really excited about the sound territory this auv3 gives me access to on iPad, and with great performance as well.
