Computational Audiovisual Composition Using Lua

We describe extensions to the Lua programming language constituting a novel platform to support practice and investigation in computational audiovisual composition. Significantly, these extensions enable the tight real-time integration of computation, time, sound and space, and follow a modus operandi of development going back to immanent properties of the domain.

Closures in Lua

First-class functions are a very powerful language construct and a fundamental feature in functional languages. However, few procedural languages support this feature, due to their stack-based implementation. In this paper we discuss a new algorithm for the implementation of first-class functions used in the implementation of Lua 5.x. Unlike previous techniques, our algorithm does not need stat...
