A long-time studio standard, now finally available for iOS! This is a direct 1:1 port of Audio Damage's Eos 2 desktop plug-in, identical in every way to the Eos you know and love. This download includes an AUv3 App Extension for use in AUv3-savvy hosts like AUM, AudioBus, GarageBand, Cubasis, and Auria Pro. Also included is a stand-alone application with Inter-App Audio.

Eos 2 consists of four high-quality custom-designed reverb algorithms, made with the modern production environment in mind. Three different plate simulators and our own Superhall algorithm give you a broad palette of reverb, and the easy-to-understand interface makes adjusting the algorithms to suit your track incredibly simple.

Want a traditional dark plate reverb? Eos 2 can do that. How about a short, dense room sound for your drum buss? Not a problem. But where Eos 2 really comes in to its own is when you drop Superhall on your piano or synthesizer tracks. The incredibly long modulated hall sounds of Eno-style ambience are where Eos 2 thrives, something that is not possible with convolution 'verbs.


> Four reverb algorithms designed for Audio Damage by ValhallaDSP, including three separate plate algorithms and our own unique SuperHall, a rich, densely modulated, extra-long hall algorithm designed for ambient and synthesizer music.

> Full control over the reverb early reflections and tail, with modulation and equalization control, to sculpt the density and tonal characteristics to your needs.

> All presets from the desktop version included, and you can even share presets among all versions of Eos 2 using the copy/paste mechanism.

> AUv3 and IAA standard.

> Note that Eos 2 is a dense, heavily modulated algorithmic reverb, and as such may be somewhat heavy on the CPU, especially on older devices. For best results, use a single instance as a send.

What's New

Version 2.0.203

All-new and much improved preset manager, with a common folder that the standalone and AUv3 share, named preset saving in the AUv3, font size increase for easier readability on small devices, and some minor internal bug fixes.

The reverb it generates is phenomenal - it has a lot of issues with GarageBand. 5 stars though because this could be GB’s side of things. And maybe the app is too large for my iPhone 6. It crashes the audio playback every now and then. Anytime GB “optimizes performance” the app shuts down and your forced to reload and reset the settings. Rather frustrating however the reverbs generated from it it is the best I’ve heard on iOS.


Awesome and massive

This makes a day and night difference. However, in the preset drop down, while scrolling, it is selecting and changing the preset. It should only select the preset when tapped on it - not while scrolling. Currently, the only way to scroll is by using the scroll bar.

Also, to the user who said it occupies only a 3rd of the screen, this is correctly implemented - it is inserted as an AU plugin into other apps and it needs to be no more than half the screen height in the host app.


Excellent sound needs better GUI

I'm using this patched into my eurorack synth using an Endorphins "cockpit" mixer module that has TTRS channels to use with iOS devices. I love the sounds of the plate reverbs and other fx. The problem for me is the GUI. The knobs are very small and text minuscule. I wish I could zoom into sections of the interface to make the controls easier to see.
