Antescofo is a program developed by Arshia Cont in 2007 at IRCAM in collaboration with composer Marco Stroppa to aid with the synchronization of electronics in live performances.
Even if the trigger is synchronized at the beginning, there may still be a temporal discrepancy between both after a certain duration due to the natural inflection of time on the part of the human performer.
Antescofo is able to recognize adjustment in tempo in real time through audio stream from live performers and detect its position in an input score, thus allowing synchronization.
Some features also exist in NoteAbility Pro, a notation program developed by Keith Hamel, to export information specifically for Antescofo.
[3] Antescofo is equipped with a dedicated real-time synchronous language as an aid to compose mixed pieces as association of live performers and computers.
