'Synopsis Seriation, ' Hecker's latest release with Editions Mego, draws upon current research in machine listening and music information retrieval, where the 'ghosts in the machine' are unsupervised, engineered operators designed to extract auditory features from a signal. The album advances a general research programme Hecker initiated through various projects. In 'A Script for Machine Synthesis' (EMEGO 226, 2017), the third chapter in the trilogy of text-sound pieces in collaboration with Reza Negarestani, both a resynthesized and a computer-generated voice modelled after the narrators voice, reflect on systems of language, automatons and chimerized synthesis. 'Articulação Sintetico' (EMEGO 180C, 2017) - a complete resynthesis of 'Articulação' (EMEGO 180, 2014) - features synthetic voice models of Joan La Barbara, Sugata Bose and Anna Kohler. Central to 'Inspection II' (EMEGO 268 / UF047, 2019) is a bespoke computer-generated voice, reciting Robin Mackay's libretto - by means of deep neural networks and machine listening computation, perpetually crossing formal anticipations of sound analysis to the unexpected artefacts of synthesis*.
