REAL TIME SPECTRAL EXPANSION FOR CREATIVE AND REMEDIAL SOUND TRANSFORMATION
Jeremy J. Wells, Damian Murphy · 2003
In this paper we describe the implementation, use and applications of WaveThresh, a real time Fourier\\wavelet spectral expander. Expansion and reverse-expansion of spectral components is offered. In order that analysis methods can be better adapted to the signal we offer a combined wavelet\\Fourier mode. This mode separates sinusoids from the rest of the signal (residual) and applies Fourier analysis to the sinusoids and wavelet analysis to the residual. 1.
