## What is Eos 2?

**Description:**

Eos 2 is Audio Damage's studio-quality algorithmic reverb, now with five custom reverb algorithms designed in collaboration with Sean Costello of Valhalla DSP. Available as an AUv3 App Extension for hosts like AUM, AudioBus, GarageBand, Cubasis, and Auria Pro, and as a standalone application.

Five algorithms give you a broad palette of reverb for any production context. Three plate algorithms cover everything from tight, dark vintage plates to wide stereo ambience. The new Random Plate algorithm produces organic, evolving reflections that never quite repeat, and is beautiful on pads, keys, and vocals. SuperHall delivers the incredibly long, densely modulated hall sounds that Eos has always been known for: Eno-style ambience that simply isn't possible with convolution reverbs.

The streamlined interface makes it easy to dial in exactly the sound you need, from a short, dense room on your drum bus to an infinite wash of sound on a synthesizer pad.

**Features**

- Five reverb algorithms: Mono Plate, Stereo Plate 1, Stereo Plate 2, Random Plate, and SuperHall

- Full control over pre-delay, room size, decay time, attack, and diffusion

- Rate and depth modulation for lively, animated reverb tails

- Three-band EQ with adjustable crossover points to sculpt the tonal character of the reverb

- Infinite mode for drones and sustained textures

- Mix lock preserves your wet/dry balance when browsing presets

- Resizable interface with real-time waveform display

- Factory presets included, with full cross-platform user preset management

- AUv3 App Extension and standalone application

- Note: Eos 2 is a dense, heavily modulated algorithmic reverb. For best results on older devices, use a single instance as a send effect.

## Key features

- Five custom reverb algorithms

### 5/5 — Character verb

*2024-09-09*

Has its own distinctive feel, silky, somewhat 90s hardware vibe

### 1/5 — crash on launch

*2024-09-03*

crash on launch on ios 17 and ipad os :(

### 5/5 — Beautiful lush reverb

*2023-11-17*

Great for quickly dialing in bottomless, lush reverb sounds, and a great deal.

### 5/5 — Stopped working on iPad with last update

*2023-11-13*

This is a truly beautiful reverb and used on most my projects! A couple hundred just on my iPad for both production and live use. Thank you for fixing the issues so it could work on our earlier devices again. In my case the projects couldn’t even be opened. Balance has been restored 🙏🏼

### 1/5 — Stopped working on iPad with last update

*2023-10-31*

Was a beautiful reverb and used on most my projects. I hope it can be fixed to continue to work with mine and seemingly other people’s devices. Will gladly update review if it starts working again!

### 3/5 — stopped working on my old ipad

*2023-10-06*

all the sudden is not working, it is saying that the helper app can’t be found... idk why? can it be fixed? tried to uninstall and reinstall, didn’t help

### 2/5 — User presets not saving

*2023-06-20*

Love the reverb however when I try to save my adjusted and renamed settings, the app does not save them under User presets or factory. This is on iPad. 

On the iPhone, I can’t even open the app by itself. Have to use a host app - AUM. 
Please fix both of these issues.

### 5/5 — Really is Studio Quality

*2023-03-28*

Wow, I have many different reverbs which I use in Cubasis 3, but Eos 2 is on another level.  The L—-O—-N—-G tails are so smooth and haunting, I absolutely love it. 
This is my go-to reverb from now on👌more than worth the cost.

### 5/5 — A fantastic reverb plug-in

*2023-03-20, version 2.1*

Excellent work here, audio damage is one of the greats bringing pro audio apps to iOS

### 5/5 — One of the best

*2022-10-17*

Tried the fab, have the BLEASS, have toneboosters…. Did I need this one? Yep.  It’s awesome.  I’m a commercial keyboardist.  If you are willing to pay for apps, just buy it.

### 2.3.1 — 2023-09-29

### 2.1 — 2019-08-14

We are very pleased to bring you this major update to one of our flagship products. 

1. NEW USER INTERFACE. For Eos’ 10th birthday, we have given it a facelift, and brought It up to date and more in line with our younger products.

2. COMPLETE REFACTORING. Internally, we have replaced most of what we call the “old framework” (which is to say code from before we made iOS products) with our current cross-platform parameter management and support code. This results in a future-proofed Eos that is built to all current plugin standards, and which uses all the latest SDKs and APIs. 

3. BETTER CROSS-PLATFORM COMPATIBILITY. The original iOS version of Eos was a separate build process from the desktop Eos. Now, they are identical in all respects, built from the same code-base.
