Unfiltered Audio TAILS

Unfiltered Audio TAILS is a creative reverb plugin developed in collaboration with producer and technologist BT. It takes a different approach to reverb by using a polytonal, dual-buffer design with intelligent auto-ducking that keeps your reverb tails pristinely clean, even on busy mixes. If standard reverbs feel cluttered or muddy to you, TAILS was built to solve that exact problem.

How It Works

TAILS constantly analyzes incoming audio, listening for transients and note changes. When a transient hits, the plugin ducks the reverb and seamlessly switches to an empty reverb buffer that blooms rapidly. The result is a tail that never accumulates mud from overlapping notes. It can even pre-duck incoming transients before they enter the reverb, keeping the tail unusually smooth. This dual-buffer approach means you get lush, sustained reverb without the buildup that plagues traditional algorithms.

Four Algorithms and Shimmer

The plugin includes four distinct reverb algorithms: DEEP for rich, cavernous spaces, RENOUN for classic reverb character, SPATIAL for wide stereo imaging, and SHIMMER for octave-shifted, crystalline tails. The shimmer mode is particularly well-implemented, producing musical pitch-shifted trails that stay consonant rather than devolving into metallic artifacts. Each algorithm responds to the ducking system, so even the most ethereal shimmer stays controlled and usable.

MIDI Control and Performance

TAILS offers advanced MIDI integration that sets it apart from most reverbs. You can use MIDI note messages to mute the buffer for rhythmic gating effects, and map the mod and pitch wheels to create expressive, performable reverb. CPU usage is remarkably low at under 1% on Apple Silicon, so you can freely stack instances across your session. The plugin supports AAX, AU, VST2, and VST3 formats on both macOS and Windows.

Who Is This For?

• Ambient and electronic producers who want endlessly clean, shimmering reverb tails
• Mix engineers tired of reverb mud and transient buildup on vocal and instrument buses
• Sound designers looking for a performable reverb with MIDI control and rhythmic possibilities
• Film and game composers who need lush, evolving spaces that stay out of the way of the source material

TAILS is typically priced around - but frequently goes on sale through Plugin Alliance for significantly less. At any price, it is a genuinely unique reverb that solves a real problem. If you have ever wished your reverb tails were cleaner and more musical, TAILS delivers exactly that.
