To use Sonia and SoniaHelper for sound input, download Processing - soundlibs.zip. Create a folder called “libraries” inside your sketchbook folder and put the contents of the archive inside it. When you restart Processing you should see the new libraries under the “Sketch > Import library” menu”.

On Mac you need to install the JSyn plugin in order to get Sonia to work.
