L’intérêt pour ces applications est de disposer ainsi d’une chaîne de compilation complète, permettant de traduire les traitements synchrones, écrites en Faust, en code binaire exécutable fonctionnant donc à vitesse native. En s’appuyant sur la technologie LLVM cette chaîne de compilation est totalement autonome et ne dépend d’aucun outil de développement extérieur. Ceci facilite grandement le déploiement auprès d’utilisateurs non informaticiens. Elle est en outre très rapide, rendant ainsi dans de nombreux cas la phase de compilation transparente pour l’utilisateur. Le rapport présente la libraire libfaust, l’infrastructure de compilation LLVM, et trois applications de cette technologie : faustgen ̃ un plugin Max/MSP permettant d’éditer, de compiler et d’exécuter du code Faust depuis Max, FaustNode, une extension de la WebAudio API permettant de compiler et d’exécuter du code Faust depuis un navigateur Web et faustcsound, un ensemble de quatre opcodes pour intégrer Faust dans le langage Csound.}, keywords = {audio, Domain Specific Language, DSP, FAUST, real-time}, pubstate = {published}, tppubtype = {techreport} } Faust est un langage de programmation de type fonctionnel synchrone conçu spécifiquement pour la synthèse et le traitement du signal audio-numérique en temps-réel.
