The main goal of the work here described is the DSP implementation of innovative algorithms for real-time voice transformation. This work represents part of the procedure (developed in the framework of the RACINE-S European Project) conceived for reconstructing voice and dialogue in audio tracks of old and highly damaged film movies.
In this paper we describe the experience of researchers and artists involved in the activities of the “computer ART lab” (cART lab) of the italian National Council of Research (C.N.R.) in Pisa, regarding the “wireless technology” developed for controlling in real-time and giving expression to interactive multimedia performances.

This paper presents a new hardware implementation of additive synthesis for high quality musical sound generation. The single-chip configuration is capable of performing 1,200 sinusoid real-time synthesis; the system is expandable to 13,200 partials by series connecting 11 chips. Each sinusoid is generated by a marginally stable second order IIR filter, and… (More)
This paper describes a set of procedures, named Toolbox, for spectral data reduction to be used in additive synthesis system based on sinusoidal model. The Toolbox has been developed in MATLAB with the specific aim to support the realization of a very large scale additive synthesis system (AddSynth) based on special purpose VLSI chips. Test signals and… (More)
