AltiSpace review – New convolution reverb app from Igor Vasiliev

In my most recent post, I talked about my five favorite developers of iOS music apps. In a nice bit of timing, one of those developers, Igor Vasiliev, has just released a new app, AltiSpace. As with his other apps, it is brilliant, and highly recommended.

If you're like me, you more than likely already have one (or more) reverb effects apps. I'm a huge fan of AUFX: Space by Kymatica, which can give you enormous reverb (Infinite Space, anyone?), and fits very well in my workflow when creating some large, ambient synth and drone pieces. There is also a lot of praise for AudioReverb by Virsyn.

But what sets AltiSpace apart from existing reverb apps is that it is a stand-alone convolution reverb app. Convolution reverb has previously only been available on desktops, or within the Auria DAW. This type of reverb is different from the existing algorithmic reverb apps, and is quite a welcome entry to iOS.

I'm going to let Wikipedia describe exactly what convolution reverb is, and how it works:

In audio signal processing, convolution reverb is a process used for digitally simulating the reverberation of a physical or virtual space. It is based on the mathematical convolution operation, and uses a pre-recorded audio sample of the impulse response of the space being modeled. To apply the reverberation effect, the impulse-response recording is first stored in a digital signal-processing system. This is then convolved with the incoming audio signal to be processed. The process of convolution multiplies each sample of the audio to be processed (reverberated) with the samples in the impulse response file

AltiSpace ships with over 200 presets, from some of the most famous devices used. Some options, as can be heard in the Soundcloud demo below, are the Lexicon 480L, Klark-Teknik DN780, and the EMT140. Admittedly, I am not a reverb historian, but when I heard that the EMT140 was the only reverb unit on Pink Floyd's Dark Side of the Moon, say no more, I'm sold.

If 200 presets weren't enough, AltiSpace also allows you to import your own IR's into the app, and very easily I might add. You can import your .wav files through iTunes sharing, or simply copy/paste or opening in apps like Audioshare. There are a lot of great impulse response files available for free on the 'net, including from Voxengo, and some "classic" and "King Tubby" style IR's from Dubbhism.

If you've purchased any of Igor Vasiliev's previous apps, the interface will look very familiar, as it retains the same look and feel. Almost everything you need will be on one page, and is very easy to use. After selecting your preset, the IR will appear graphically in the box at the bottom of the screen. This will give you a representation of what the IR looks like. An option here is to reverse the IR, which will give you some great reverse reverb. This is a ton of fun, to bring in a great "swell" reverb sound.

Above this, in a larger box, is the equalizer, where you can adjust the EQ as well as a simple low-pass and high-pass filter. You can save eight presets in hotkeys at the top of the screen, which is nice if you've got some "go-to" reverbs. On the right side of the screen you will find the presets, organized nicely by either "group" (i.e. spring, plate, halls) or by device (i.e. EMT140, M5000, etc.). Sliders for adjusting volume, reverb amount and stereo and modulation are found below, alongside the input and output monitors.

I had a lot of fun using AltiSpace on a variety of apps. Sending DM-1 through AltiSpace in Audiobus, I was able to get some huge John Bonham "When the Levee Breaks" reverb. And just for kicks, I loaded up Bebot and ran through some presets. I'm not kidding when I say that AltiSpace breathes new life into Bebot, really thickening up some of the sounds.

AltiSpace is Audiobus compatible, and I had no issues with it working as it should. It is also IAA-compatible, and as a nice surprise, is also a universal app.

I've got nothing but good things to say about AltiSpace. You won't find any of the "out there" reverbs here that you can find in algorithmic reverb apps. The reverbs here are very subtle, and very organic sounding. And with 200+ presets, and the ability to add your own IR's, I'm betting you'll find that reverb that you are looking for. This app is an easy recommend.
