Sound modelling is an important part of the analysis-synthesis process since it combines sound processing and algorithmic synthesis within the same formalism . Its aim is to make sound simulators by synthesis methods based on signal models or physical models , the parameters of which are directly extracted from the analysis of natural sounds . In this article the successive steps for making such systems are described . These are numerical synthesis and sound generation methods , analysis of natural sounds , particularly time-frequency and time-scale ( wavelet ) representations , extraction of pertinent parameters , and the determination of the correspondence between these parameters and those corresponding to the synthesis models . Additive synthesis , nonlinear synthesis , and waveguide synthesis are discussed .
