Abstract
Sinusoidal+Residual analysis/synthesis models have been developed for music
applications. They have been very successful and are already found in commercial
and experimental tools used by musicians as well as researchers. In this paper, we
present the principles of this now classical model. However, the standard version
of the model suffers from limitations in various cases. We discuss some
improvements of the standard method designed in order to overcome these
difficulties. We then present and compare other analysis techniques which use
Elementary Waveforms, i.e. waveforms localised both on the frequency and the
time axis. In particular, the High Resolution Matching Pursuit algorithm is
proposed as a potentially successful new direction of research.
