Un estratto da un brano di Philippe Manoury<\/a> (En \u00e9cho, 1993-1994, testo di Emmanuel Hocquart) in cui il computer genera suoni in tempo reale seguendo l\u2019esecuzione del soprano. In pratica il computer \u00e8 in grado di ascoltare l\u2019interprete e a fronte della partitura, riesce a seguirlo nonostante eventuali rallentando o accelerando.<\/p>\n

In questo caso tutto \u00e8 reso pi\u00f9 semplice dal fatto che l\u2019esecutore \u00e8 un solista e non un ensemble, quindi si deve seguire una sola voce, ma anche cos\u00ec non si tratta di una faccenda banale.<\/p>\n

Written in collaboration with programmer Miller Puckette, \u201cEn Echo\u201d uses real time score-following software which responds to the singer\u2019s voice. In Emille Hocquart\u2019s text, a young woman recollects a heated affair.<\/p>\n

\u201cThe computer is automatically following the voice,\u201d Mr. Manoury explained. \u201cIt functions as what we call a \u2018score-follower.\u2019 The singer sings in tempo, or with an acceleration, and the computer synchronizes to make synthetic sounds that are deduced from alterations in the voice \u2014 not precalculated, but produced in real time. If the voice modifies the vowels, for example, it modifies the electronics.\u201d Messrs. Manoury and Puckette have worked since the latter moved from the Massachusetts Institute of Technology in 1989 and joined Mr. Manoury at the famous studios at IRCAM (l\u2019Institut de Recherche et de Coordination Acoustique\/Musique), which Pierre Boulez founded in Paris.<\/p>\n
