Incudine is a music/DSP programming environment for Common Lisp. It's released under the GNU General Public License (GPL) version 2 or later.

Incudine is useful to design software synthesizers or sound plugins from scratch, exploiting the expressive power of Common Lisp, without the constraint to use pre-built unit generators. It is also a compositional tool that allows to produce high quality sounds controllable at the sample level, defining and redefining the digital signal processors and the musical structures on-the-fly.

Incudine introduces the Virtual UGen (VUG), a new mechanism for defining primitive unit generators by writing concise and reusable code. The definition of a VUG contains lisp code and/or other nested VUGs, and it is re-arranged and compiled efficiently during the creation of a DSP.


Incudine works with SBCL, an implementation of ANSI Common Lisp with a high-performance native compiler.
