This article presents new tools developed in the FAUST language to create musical interactions using electrophysiological signals as input. The tools developed are centered around signal processing and simulation of electrophysiological signals. These techniques are used to clean and process biosignals and subsequently provide real-time interactions to feed the control of sonic processes. The system provides modules that are musically expressive especially in the domain of spatial sound. These tools also allow to set up a testing environment by replacing the need of electrophysiological capture devices. The findings of this research provide a better understanding of how the FAUST language can be used in conjunction with physiological signals and brings to light interesting opportunities to explore further possibilities in music creation in an open source environment with the possibility of multitarget compilation, allowing our modules to be used either in such softwares as Max[10] or embedded in microcontrollers.
