Adaptive Signal Models: Theory, Algorithms, and Audio by Michael M. Goodwin

By Michael M. Goodwin

Adaptive sign versions: thought, Algorithms and Audio Applications provides equipment for deriving mathematical types of common signs. The advent covers the basics of analysis-synthesis platforms and sign representations. a few of the subject matters within the creation contain ideal 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 themes come up through the booklet as do a few different themes reminiscent of clear out banks and multiresolution.
the second one bankruptcy offers a close improvement of the sinusoidal version as a parametric extension of the short-time Fourier rework. This ends up in multiresolution sinusoidal modeling options in bankruptcy 3, the place wavelet-like techniques are merged with the sinusoidal version to yield more advantageous versions. In bankruptcy 4, the analysis-synthesis residual is taken into account; for lifelike synthesis, the residual has to be individually modeled after coherent parts (such as sinusoids) are got rid of. The residual modeling procedure relies on psychoacoustically prompted nonuniform clear out banks. bankruptcy 5 offers with pitch-synchronous models of either the wavelet and the Fourier rework; those enable for compact versions of pseudo-periodic indications. bankruptcy Six discusses contemporary algorithms for deriving sign representations in line with time-frequency atoms; essentially, the matching pursuit set of rules is reviewed and prolonged.
The sign types mentioned within the ebook are compact, adaptive, parametric, time-frequency representations which are beneficial for research, coding, amendment, and synthesis of ordinary indications similar to audio. The types are all interpreted as equipment 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: thought, Algorithms and Audio Applications serves as a superb reference for researchers of sign processing and will be used as a textual content for complicated classes at the topic.

Sample text

This approach is presented as an evolution of the nonparametric short-time Fourier transform into the the parametric sinusoidal model; the chapter includes detailed treatments of the STFT and analysis-synthesis methods for the sinusoidal model. Chapter 3 provides an interpretation of the sinusoidal model in terms of time-frequency atoms, which motivates the consideration of multiresolution extensions of the model for accurately representing localized signal behavior. Chapter 4 discusses the sinusoidal analysis-synthesis residual and presents a perceptually motivated model for this residual.

Primarily, the book deals with the interpretation of filter banks as analysis-synthesis structures for signal modeling. The connection between multirate filter banks and multiresolution signal modeling is explored. Signal-adaptive representations. Each of the signal models or representations discussed in this book exhibits signal adaptivity. In the sinusoidal and pitch-synchronous models, the decompositions are signal-adaptive in that the expansion functions are generated based on data extracted from the signal.

Given that a signal may have energy anywhere in the time-frequency plane, the objective of adaptive modeling is to decide where to place tiles to capture the signal energy. Tile-based interpretations of various time-frequency signal models are discussed in the next section. 24 ADAPTIVE SIGNAL MODELS Translation ..... //········0 Scaling '--___--'I ...... 8. Modification of time-frequency tiles: translation, modulation, and scaling. 2 Tilings of the Time-Frequency Plane Signal expansions can be interpreted in terms of time-frequency tiles.
