1. General Information
Welcome to MacWavelets v2.00! This program is a simple toolkit for performing
discrete wavelet transform analysis of 1d and 2d datasets. With this program you
- Import and export 1d and 2d datasets in text and binary format.
- Generate a variety of test datasets.
- Plot data in graphical and tabular form.
- Perform discrete wavelet transforms and inverse transforms using several
built-in filters, as well as custom imported filters.
- Display wavelet coefficients as 1d and 2d plots, as Scale Density images
(absolute value of coefficients in each dyad), and as Scalegrams (average squared
coefficient values in each dyad).
- Manipulate datasets with simple math and subset operations.
- Sort, truncate, and unsort coefficients.
- Compress and expand data.
- Remove noise from data.
- Find peaks in data.
- Display data statistics.
All program operations are available from the standard Macintosh user
interface, including windows, menus, and dialogs. No programming or scripting is

1.3 System Requirements
This software should run on any Macintosh which is running System 7 or later.
This software is written using MC68000 instructions and does not make direct FPU
calls. Although color is not required, it is recommended (you won't be able to
see SDP's or images without color or gray scale, however). The program should
work fine with 256 colors, but more are better. The program requires less than
500K on disk, and comes with its memory partition set to 8Mb. This (or much
less) should be sufficient to analyze modest datasets. Larger datasets will, of
course, require more memory, as will the use of more 2d image windows. Look at
the "About this Macintosh..." item under the Apple menu of the Finder to see how
much memory the program is using while it is running. If you are not using large
datasets or many 2d images, you may find that 4Mb or 2Mb are sufficient memory to
perform most analyses.
1.4 Software Installation
To install the software, simply drag the program icon to your hard disk. No
special installation or setup is required. To install the User's Manual, simply
drag the manual folder to your hard disk. The manual is in HTML format, which
can be viewed with Netscape 1.1 (e.g.) or later.
1.5 Security and Licensing
This software is distributed in a complete, but unlicensed, form. This means
that you can use the software as-is for non-profit, non-commercial, individual
evaluation purposes only. In addition, several features of the software have
been locked (disabled), including:
When you launch the software, you will see a screen containing a randomly chosen
security keyword and a password prompt:
- Saving a document
- Exporting data and plots
- Copying data and plots
- Printing data and plots
To permanently unlock the disabled features listed above, you must enter the
correct password for the keyword displayed. You may also ignore this password and
continue to use the software in its locked form. All features other than those
listed above will be available.
To receive the correct password for your keyword, you must purchase a single-user
license for the software, at a price of $25 (US) for version 2.00. This license
entitles you to use the full features of the software for individual commercial
or non-commercial purposes which do not violate the copyright or trademerk of the

purchasing a license. Therefore, the purchase price of a license is
Free MacWavelets Version 2.10
In addition to the full use of the current software, the purchase of a v2.00
license will also entitle you to a free single-user license/password to version
2.10 of the software, expected to be released in the summer of 1996. Otherwise,
the first-time purchase of a v2.10 license is expected to cost more than $25.
This offer will expire when the v2.10 software is released.
