Oasis Rose the composition - real-time DSP with AudioMulch

Oasis Rose is a composition incorporating live instrumentalists and real-time signal processing. The work makes use of algorithmically controlled non-linear signal processing techniques while attempting to maintain the “signal processing as extension of instrument ” aesthetic. Real-time signal processing is implemented using the authors AudioMulch interactive music environment for Windows 95/NT™. This paper discusses the algorithms utilised in Oasis Rose, and documents the authors experiences in bringing traditionally “studio ” or “non real-time ” signal processing techniques to the stage. Since my earliest experiences with audio effects and digital signal processing, I have been fascinated by their ability to transform and augment the sound of acoustic and electronic instruments. For electric guitarists and classic knob-box synthesists, the application of effects has been an integral part of musical performance for over three decades. While the use of “live electronics ” in performance has an established history, the use o
