**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.

"LO‑FI‑AF is a very capable lo‑fi toolkit capable of surgically targeted destruction and it could easily find applications in just about any musical genre" -SoundOnSound Unfiltered Audio's lo-fi-af is now available on iOS as a Standalone app or AUv3 plugin! lo-fi-af takes your sound on a journey of artifacts and noise throughout recorded history, from tape warbles and vinyl noise to MP3 chirps and cell phone speaker chatter. lo-fi-af's many sections and versatile algorithms can place your sound in a different decade, or give it a thoroughly modern spin through compound processing. The first section is a convolution reverb preloaded with impulse responses from broken microphones, toy speakers, cell phones, and more. With this section alone, you can place your sound into an entirely different space. The Spectral section then splits your sound into thousands of frequencies before reconstructing it with a twist. Here you can reproduce the sound of a pirated MP3 or pitch shift your signal with clean perfection. Your signal then takes a trip through the digital section. All sorts of hazards are present here, from a skipping CD stutter effect to a multimode bitcrusher. Finally, the rich, colorful analog section adds that vibe that you crave. A maximizer, a tape saturator, a noise generator, an analog-style filter, a pitch warbler, and a radio demodulator all work together in harmony to toss your sound into the past. But wait! That's only one possible signal chain. The Convolution, Spectral, Digital, and Analog sections can be completely rearranged in any order. Dozens of presets will get your started on your sound warping adventure. As an AUv3 plugin, lo-fi-af has been tested to work perfectly with Garageband, Drambo, AUM, Cubasis, Beatmaker, Nanostudio, apeMatrix, Loopy Pro, and more! Additionally, with its clear layout and smart resizing, lo-fi-af can be used on tablets and phones with ease. (Note for Drambo users: Drambo does not yet have automatic Plugin Delay Compensation for managing plugins with latency. As a result, tracks with lo-fi-af will not line up properly with other tracks. An upcoming patch for Drambo will add this feature in.)
