Presentation
Chorus digitalis is the first choir in the world composed of synthetic voices controlled in real time by graphic tablet. The synthetic voice instrument is called Cantor Digitalis/ /* REMOVE THIS LINE TO UNCOMMENT /. Resulting from research on the gestural control of voice synthesis initiated in 2005 by Christophe d'Alessandro, Chorus digitalis has publically performed for the first time in March 2011 in Vancouver with its designers, Sylvain Le Beux, Boris Doval, Lionel Feugère and Christophe d'Alessandro. The current project is led by Lionel Feugère and Olivier Perrotin. Controlling a voice using hand gestures is surprisingly easy: it is an intuitive control, which takes advantage of the skill acquired by writing. Learning is rather fast compared to that of other musical instruments. Chironomy, i.e. connecting hand, gesture and music, is our beautiful research topic. Synthetic voice is computed from a source-filter model, which reproduces the operation of the vocal apparatus. The source simulates changes in air flow at the glottis, and the filter simulates the filtering effect of the vocal tract. The parameters of this model are controlled by a stylus on a graphics tablet, the pressure and position in the two spatial dimensions can define the strength of voice, pitch and vocalic color. The synthesizer produces sung vowels, carefully setted to make traditional voice types: baritone, tenor, alto, soprano. Unusual voice types are also available, playing on the glottal source. Voice synthesis as realistic as possible, but which can get ridd off its model, here is a theme of research already old, but still new. Virtual voice lends itself to all kinds of music games, written or improvised, from the accompagning chorus to complex polyphony, through the solo voice singing in the style of North India, baroque Opera or contemporary music. The ensemble was started with the European project (FEDER) OrJo and is now funded by the ANR projectChaNTeR. It is part of the research of the LIMSI's Analyse & Synthèse Audio sub-team and transversal research axis VIDA.
