Phil Burke's Jsyn http://www.softsynth.com/jsyn/ JSyn allows you to develop interactive computer music programs in Java. You can run them as stand-alone applications, or as Applets in a web page using the JSyn Plugin. JSyn uses native methods written in 'C' to provide real-time audio synthesis for Java programmers. JSyn can be used to generate sound effects, audio environments, or music. JSyn is based on the traditional model of unit generators which can be connected together to form complex sounds. For example, you could create a wind sound by connecting a white noise generator to a low pass filter that is modulated by a random contour generator. check all the fine examples http://www.softsynth.com/jsyn/examples/ I guess this could a nice use of Jython too enjoy ./Jason
