A next-generation reverb that’s creative and clean

Unfiltered Audio joins forces with superstar producer BT to create a reverb that provides unparalleled sound expansion and consonance. Thanks to its “polytonal dual buffer” and auto-ducking capabilities, TAILS automatically removes dissonances and transients from your reverb tails, keeping your decays as clean and impressive as possible.

Unique filter capabilities

TAILS analyzes incoming audio, listening for major transients and note changes. Whenever its threshold is met, the reverb instantly ducks and switches over to an empty reverb buffer, which blooms rapidly. This results in a clean reverb decay that is free of discord from metallic hits and out-of-key notes. It can even pre-duck incoming transients to keep them from ever cluttering up your reverb, to begin with, providing a tail that’s unusually smooth.

Four reverb engines in one

TAILS features multiple reverb engines for even more creative choices, including the beautiful new SHIMMER mode, tuned to BT’s exacting tastes. Also on board are the classic DEEP and RENOUN modes found in BYOME, and the surreal SPATIAL mode from SILO.

Powerful & CPU efficient enough

Even with all of these wild features, TAILS is the perfect workhorse reverb. With less than 1% CPU usage on an M1 Macbook Air, you'll be able to add Tails to any track without worrying about it. Advanced MIDI integration allows you to use note messages to mute the buffer for rhythmic interest and precise editing, and to create unique performance opportunities with the Mod and Pitch Wheels.
