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