Languages for music audio processing typically offer a
large assortment of unit generators. There is great duplication
among different language implementations, as each
language must implement many of the same (or nearly the
same) unit generators. Csound has a large library of unit
generators and could be a useful source of reusable unit
generators for other languages or for direct use in applications.
In this study, we consider how Csound unit generators
can be exposed to direct access by other audio processing
languages. Using Aura as an example, we modified
Csound to allow efficient, dynamic allocation of individual
unit generators without using the Csound compiler or
writing Csound instruments. We then extended Aura using
automatic code generation so that Csound unit generators
can be accessed in the normal way from within Aura. In
this scheme, Csound details are completely hidden from
Aura users. We suggest that these techniques might eliminate
most of the effort of building unit generator libraries
and could help with the implementation of embedded audio
systems where unit generators are needed but a full
embedded Csound engine is not required.
