About Tails - Dual Reverb
Unfiltered Audio's Tails is now available on iOS as a Standalone app or AUv3 plugin!
Unfiltered Audio joined forces with electronic music superstar BT to create Tails, the world's most harmonic reverb.
Tails utilizes a novel double-buffered technology to create two separate reverbs in parallel. The twist comes with special threshold swapping: Whenever Tails detects a major change in amplitude or tone, it can smoothly swap between the two reverbs. Additionally, Tails can auto-duck on its inputs and outputs.
This keeps your reverb as clean as possible. With auto-ducking on attacks, you can keep the metallic noise of percussive hits out of your reverbs. Alternatively, you can keep passing tones and blue notes out of your melodic echoes so that your reverb is free of dissonance.
Even without its innovative ducking and swapping, Tails is the most flexible reverb in your arsenal. Two of Unfiltered Audio's classic BYOME reverb algorithms (Renoun and Deep) are available with a Spatial mode inspired by Silo and a brand new Shimmer mode designed to BT's exacting specifications. In true Unfiltered Audio fashion, a global Sample Rate knob affects the sampling rate of the entire DSP algorithm, stretching your reverb tails out into crispy, lo-fi oblivion.
Finally, Tails is built to be performed. Your MIDI keyboard's Pitch and Mod wheels can be assigned quickly to a selection of key parameters, while Note messages can be used to manually duck or mute the reverb.
As an AUv3 plugin, Tails 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, Tails 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 Tails will not line up properly with other tracks. An upcoming patch for Drambo will add this feature in.)

Latest updates
1.2.0
1.2.0:
Tails now has import and export of User Presets!
- Exporting will create a .zip file of all User Presets. You can save this .zip file to Files or iCloud for easily transferring presets saved on iOS back to your other computers.
- Presets can be imported as single .uap files or as a .zip. Importing a .zip will extract the contents of the file directly to your User Presets folder.
Additional patches:
- The Reverb Swap Speed parameter now responds more intelligently when typing in values. Typing a value like "0.6" will assume seconds, while a larger value like "600" will assume milliseconds.
- Versions 1.07 through 1.1.0 were not released on iOS, as they did not feature any changes/fixes for iOS.
