This paper presents real-time musical applications using the IRCAM Signal ProcessingWorkstation which make use of FFT/IFFT-based resynthesis for timbral transformation in acompositional context. An intuitive and straightforward user interface, intended for use bymusicians, has been developed by the authors in the Max programming environment. Techniques for filtering, cross-synthesis, noise reduction, and dynamic spectral shaping are presented alongwith control structures that allow for both fine timbral modification and control of complex soundtransformations using few parameters
