  • The outer reaches of the human voice

    Explore the outer reaches of the human voice with this incredibly unique world of cutting-edge textures, rhythms and evolving drones. Curated and produced by composer and sound artist Lea Bertucci, this powerful tool captures the radical visceral vocalisations of herself and three renowned pioneers of the avant-garde — Audrey Chen, Cansu Tanrikulu & Phil Minton. From earth-shaking bass drones to window-shattering sound effects, whispers, rhythmic clicks and glissandi to haunting multiphonic choirs; these alien-like instruments will hum, hiss, heckle and haunt to create immediate tension, atmosphere, horror and beauty — a wealth of delights and terrors for any experimental producer, beatmaker or film composer. 

    The plugin’s radically transformative processed signal and in-built controls take the organic sounds to new sonic realms to create complex otherworldly synth textures, rhythms and sound effects beyond your wildest dreams — designed to inspire and breathe new life into your compositions.
