Embedding native audio-processing in a score following system with quasi sample accuracy

ICMC 2016 - 42th International Computer Music Conference, Sep 2016, Utrecht, Netherlands

This paper reports on the experimental native embedding of audio processing into the Antescofo system, to leverage timing precision both at the program and system level, to accommodate time-driven (audio processing) and event-driven (control) computations, and to preserve system behaviour on multiple hardware platforms. Here native embedding means that audio computations can be specified using dedicated DSLs (e.g., Faust) compiled on-the-fly and driven by the A... read_more

This paper reports on the experimental native embedding of audio processing into the Antescofo system, to leverage timing precision both at the program and system level, to accommodate time-driven (audio processing) and event-driven (control) computations, and to preserve system behaviour on multiple hardware platforms. Here native embedding means that audio computations can be specified using dedicated DSLs (e.g., Faust) compiled on-the-fly and driven by the Antescofo scheduler. We showcase results through an example of an interactive piece by composer Pierre Boulez, Anthèmes 2 for violin and live electronics.

An Efficient Scheduling Algorithm for Real-Time Musical Systems

International Computer Music Conference, 1990, Glasgow, United Kingdom. pp.194-198

Scheduling problems hold an important place in most real-time musical systems. We here present an algorithm allowing to solve these problems efficiently and ensuring a bounded low scheduling cost per event in any circumstances. Its principle is to maintain events all the better sorted out as their running time gets closer.
