Get Adaptive Signal Models: Theory, Algorithms, and Audio PDF

By Michael M. Goodwin

Adaptive sign types: idea, Algorithms and Audio Applications offers tools for deriving mathematical versions of normal signs. The advent covers the basics of analysis-synthesis platforms and sign representations. a few of the themes within the creation contain excellent and near-perfect reconstruction, the excellence among parametric and nonparametric tools, the position of compaction in sign modeling, uncomplicated and overcomplete sign expansions, and time-frequency solution matters. those subject matters come up in the course of the publication as do a couple of different themes corresponding to filter out banks and multiresolution.
the second one bankruptcy provides an in depth improvement of the sinusoidal version as a parametric extension of the short-time Fourier rework. This results in multiresolution sinusoidal modeling options in bankruptcy 3, the place wavelet-like ways are merged with the sinusoidal version to yield stronger versions. In bankruptcy 4, the analysis-synthesis residual is taken into account; for lifelike synthesis, the residual needs to be individually modeled after coherent parts (such as sinusoids) are got rid of. The residual modeling procedure relies on psychoacoustically influenced nonuniform filter out banks. bankruptcy 5 offers with pitch-synchronous types of either the wavelet and the Fourier remodel; those permit for compact types of pseudo-periodic signs. bankruptcy Six discusses contemporary algorithms for deriving sign representations according to time-frequency atoms; essentially, the matching pursuit set of rules is reviewed and prolonged.
The sign versions mentioned within the ebook are compact, adaptive, parametric, time-frequency representations which are worthy for research, coding, amendment, and synthesis of average indications such as audio. The types are all interpreted as tools for decomposing a sign when it comes to basic time-frequency atoms; those interpretations, in addition to the adaptive and parametric natures of the versions, serve to hyperlink a few of the tools handled within the textual content.
Adaptive sign versions: concept, Algorithms and Audio Applications serves as a good reference for researchers of sign processing and will be used as a textual content for complicated classes on the topic.
