VirSyn is no newcomer to high quality music software development, yet I was still caught by surprise when I saw they released a new stand alone Reverb effects app. Interesting timing. We just saw two others very recently.
Audio Reverb is very different. Most reverbs are algorithmic types that emulate various spaces and whatnot. In this case we have an Impulse Response type that is from real recordings of natural acoustic reverberations. Additionally classical algorithms are included to recreate their acoustical properties.
The combination makes for some of the most amazing and most natural-sounding reverberation effects. This is currently the very best sounding of the stand alone reverb app types.
Audio Reverb is packed with a well designed collection of the most important adjustable parameters allowing massive design potential. VirSyn understands the importance of “Early Reflection” and full user control. Our ears perceive these early reflections and basically translate to our brain what sort of room is being heard. Is it big or small, or made of wood or concrete etc.
From those room sizes, and how frequencies are absorbed, to even discerning the materials in the walls of said rooms.
This is pretty dang important and if done right (as I believe VirSyn has here) is what separates good from great to the spectacular Reverb units.
How you adjust the “Early Reflection” parameters will have a big effect on the overall sound being recreated, and with much variety.
It can be complex stuff, and even subtle adjustments can impact what’s heard. With the quality of this app’s design, there are numerous possibilities to stumble upon, or seek out specifically. As complex as this is, don’t sweat it this app has hundreds of very carefully crafted presets to suit most any need ready for you.
In addition to thoughtful attention to early reflection parameter details, Audio Reverb also contains a sophisticated Tail Equalizer. The “Tail Equalizer” controls frequencies contained in the early reflections and the reverberation tail. This is where you set “color” or “temperature” to a room. It does not filter the direct signal.
With the Hi/Lo shelving filters, and the LoMid & HiMid frequency peaking filters, including gain and resonance controls you can have any “color” or “temperature” you like. These types of filters are relatively common among reverb units, but there is something special about what VirSyn has given us in this app. It makes a difference you can really hear.
It all comes together and becomes cohesive with the “Room Parameter” section of controls.
Often other iOS reverbs ignore things found in this section. In order to define the reverberation effect best, a well made selection of parameters to basically recreate a room or space is needed.
Tail Delay is directly related to the room size being simulated.
Room Size essentially moves the walls of the room in or outward. Setting the distance between the walls.
The Diffusion parameter controls the density of echos from the reverberated sound and the adjustable range is very effective.
The higher the setting, the more dense the echo is, and will lend to a more natural sound.
The often forgotten Absorption parameter is very welcome. It simulates the surface and air absorption of high frequencies. More absorption affects high frequencies making them shorter than low frequencies. A higher sound will die out faster as this is increased.
Tail Stereo and Reverb Time set the tail stereo width, and the overall length of decay from the initial sound entering the simulated room. An astonishing 100 seconds is the maximum time setting. Sometimes its like the sound just keeps going on and on further and further away. It doesn’t just end (unless you want it to and set a short time) or suddenly peter out in a coarse halt. Its super smooth, and natural. It is as if the sound continues infinitely beyond what you can hear. It’s a quality that adds a feeling of the sound being timeless, figuratively speaking. Really this sounds the most natural of all stand alone reverb options by a wide margin.
Audio Reverb is of course Audiobus supported at the FX and Output slots. You can record directly to the app through your device mic or iRig Mic (any compatible mic), and is also complete with AudioCopy/Paste. iTunes File Share (Just being a little sarcastic)is also supported for some reason. Furthermore recordings can be uploaded straight to your SoundCloud.
Another cool feature of Audio Reverb is you can play your own music from your iTunes Library. Add some reverb effect to any song. Try Pink Floyd’s “GoodBye Blue Sky” with a cathedral setting. Nice!
After spending a solid amount of time with this and all other iOS reverbs, and testing extensively, I have found Audio Reverb to have the very best sound quality overall. It is flexible, reliable, and has no strange anomalies. This is exactly the kind of reverb we’ve been missing. It’s better than Auria’s Classic Reverb Pro by miles.
The added waveform graphic is not just colorful and appealing, but useful for a visual queue of what’s going on with the sound.
Instead of sounding like an effect laying on top of the sound (which of course is exactly what is happening), it seamlessly blends with it as if it were always a part of it. That’s the good stuff!
As great as this is, there’s some pretty big things missing. Notably there is no MIDI integration to be found as seen in the likes of AD480 Pro or AUFX:Space. That may present a problem to some. On the other hand if like me, you’re focused more on audio and using this through Audiobus, then no problem.
Another missing feature that I was really hoping to find upon first opening this app was no chorus or swirl type modulation. Maybe I am asking for too much, but I’d love to see something added at some point.
It could also benefit from a email option to share user presets.
Its been very stable in all my tests with iPads 3 & 4 through Audiobus, and with other demanding synth apps. This is a powerful reverb that doesn’t get in your face demanding power. I’m sure there is a way to over do it, but in regular to heavy use its not been a problem for me.
If you want a big, natural sounding reverb, don’t mind the lack of MIDI, and have $10 then you should probably get this.
I wish I had Audio Reverb a couple years ago.
