**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.
Velvet Machine
This audio effect plugin generates unique sonic textures by blurring and stretching sounds. It can create reverb-like qualities, act as a delay, and offers extensive control over its volume envelope and timing. Requires a compatible host app and a relatively modern device for optimal performance.
- Real-time convolution with enveloped velvet noise
- Sound stretching and blurring up to 10 seconds
- Reverb-like textures with flexible volume envelope
- Variable density random multi-tap delay
- Host tempo sync for time and predelay
- High cut and low cut filters
- Adjustable dry/wet mix

Sonic texture generator / blur / non-linear reverb *** WARNING *** Velvet Machine is an Audio Unit v3 plugin and requires a compatible host such as GarageBand, AUM, Cubasis, Audiobus etc. The provided standalone app does NOT support the currently deprecated Inter-App Audio. *** Velvet Machine is a CPU-intensive effect at high settings. A *minimum* of 5th Gen iPad, iPhone 6s or 1st Gen iPhone SE is required to run a single instance at maximum settings. However, shorter times and/or lower densities use much less CPU. *** Velvet Machine is a unique audio effect based on real-time convolution with enveloped velvet noise. It's designed to: - Stretch and blur out even short sounds to lengths of up to 10 seconds - Produce reverb-like textures with flexible volume envelope (including reverse, fading in and out, pulsating etc.) - Work as a variable density random multi-tap delay (bordering on granular-like sounds) PDF manual and video demos are available on developer website. Features: - Flexible volume envelope with arbitrary number of segments and curvature - Effect time ranging from 50 ms to 10 s - Response density adjustable from 1 to 2000 repeats per second - Predelay up to 1 s - Host tempo sync for time and predelay parameters - High cut and low cut filters for the effected signal - Mix adjustable from 100% dry to 100% wet - Mix Lock to switch presets while keeping the dry/wet mix constant
