Abstract
This paper describes methods for the removal and/or separation
of amplitude and frequency modulation of individual components
within a Fourier spectrum. The first proposed method has a
relatively low cost and works under assumptions about the behaviour
of both the local and non-local magnitude and phase of
sinusoidal components for these two forms of component nonstationarity.
The second method is more expensive and resynthesizes
components either in the Fourier or time domain following
a parameter estimation stage. Typical applications are the
adjustment of expressive parameters in music signals and conditioning
of signals prior to cross-synthesis.
