**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.
