\section{Concatenator}
The concatenator project aims to provide a Python framework and
command-line tool for concatenative synthesis.
The concatenator project was designed as a Python framework and
command-line tool for easy access to CS. The project aimed to provide an
open source set of tools that would allow composers to generate a variety
of CS driven realisations. In addition, the project aimed to provide an
intuitive API that Python programmers could use as fundamental building
blocks to build further concatenative synthesis applications on.
Why Python?

Offline processing to allow for large databases to be used - disadvantage: loss of feedback between performer and system, as described in PA's paper.
