Antescofo

Antescofo (main developper Arshia Cont) is a polyphonic Score Following system for mixed music live performance (involving computers and analog instruments).

This system allows for real-time automatic recognition of the position in a music score and the tempo, from an audio stream coming from performer(s) (artificial listening module), and for synchronization of pre-written computer realized elements to this instrumental performance (player module). Both the computer-played elements and the instrumental score, as well as instruction for their synchronization, must be written in a Domain Specific Language (DSL) and given in input to the system.

In the context of Inria’s team Mutant at Ircam, I have collaborated to the developpement of this Interactive Music System between 2012 and 1017, with contributions in particular to Antescofo’s parser and standalone system, and supervision of the development of timed-testing procedures.

Antescofo has been initially released as a patch for the real-time music environement Max, and distributed via Ircam’s Forum. A standalone version and an
editor for the DSL of input music scores have been developped later in team Mutant.

This software was finally transferred to the startup Metronaut by whom it is distributed it as a mobile application.
