Motivation for Wavelets and Some Simple Examples,in contrast to most sound, where the characteristics change over time. Secondly, we have seen that even if a sound has a simple trigonometric representation on two different time intervals, the representation as a whole may not be simple. In particular this is the case if the function is nonzero only on a very small time interval.

Digital Sound and Discrete Fourier Analysis,en by integrals that in most cases cannot be evaluated exactly, so some kind of numerical integration technique needs to be applied. Transformation to the ., where meaningful operations on sound easily can be constructed, amounts to a linear transformation called the .. We will start by defining this, and see how it can be implemented efficiently.

Constructing Interesting Wavelets,tiresolution analysis? An answer to this question certainly could transfer much theory between wavelets and filters. Also, it may be easier to construct good filter bank transforms than good wavelet bases.
