Software: Wavelet Software Toolbox from Aware

Aware's WaveTool, An Interactive Tool
for Wavelet and Multirate Filter Design

Cambridge, MA....March 1, 1995.... Aware announces WaveTool 1.1, a general
wavelet and multirate software toolbox for signal processing and scientific
applications. WaveTool enables the user to quickly and easily apply wavelet
methods to a wide range of applications from data compression to
telecommunications, from feature extraction to numerical analysis.
WaveTool is an interactive system for exploring this innovative new
approach. The software is available in two versions, WaveTool Filter
Design and WaveTool Signal Analysis. Features of WaveTool Filter Design
Interactive design of wavelet and multirate filter banks, from
2 to 4096 channels
Point-and-click graphical user interface
A library of predesigned wavelet (orthogonal and biorthogonal) and
cosine-modulated filter banks
The ability to set filter performance parameters such as:
- stopband attenuation
- transition bandwidth
- flatness (vanishing of wavelet moments)
Interactive graphical display, featuring:
-time and frequency domain plotting
-the ability to measure perfect reconstruction error
-display of wavelet scaling functions
The capability of saving filters in ASCII and MATLAB formats.
Log files recording user actions for editing, playback, and software
WaveTool Signal Analysis includes all the features of WaveTool Filter Design
plus extensive algorithm prototyping functions, including:
Interactive creation of arbitrary tree structures of filter banks
(such as Mallat's wavelet tree)
Graphical display of filter bank responses at any node of the tree
Multirate analysis and synthesis operations on user data
Choice of boundary handling methods
Choice of subband analyzer or transmultiplexer modes. Graphical
display of subband outputs.
The ability to read and write transform data to ASCII and MATLAB files
The capability to invoke these algorithms via MATLAB-callable
functions for inclusion in larger simulations.
With Wavetool's easy-to-use GUI and MATLAB compatibility, the user doesn't
have to learn a new language or make a big investment.

WaveTool is available for Sun O/S, Solaris and IRIX (SGI) systems. A
graphical demonstration of the software is available on Aware's World Wide Web
site, For more information, or to order a copy, contact
