Sporth (short for SoundPipe fORTH), is a small stack-based musical language, roughly inspired by stack languages like Forth and PostScript.


  • Stack oriented paradigm
  • Written entirely in C
  • 100+ unit generators to choose from
  • Powered by the Soundpipe DSP library
  • Unix-Friendly
  • Small codebase
  • Powerful C API
  • Easily extendable
  • Easily embeddable


In order to compile Sporth, SoundPipe needs to be installed.


  1. make
  2. sudo make install

#Quick start

To see Sporth in action, run this command from the inside the project directory:

sporth -d 5s -o dialtone.wav examples/dialtone.sp

This will generate a 5 second audio clip of sound.

More information on Sporth can be found here.


Several examples demonstrating specific ugens can be found in the examples folder of the repository. More musical examples can be found on the Sporthlings page.
