Introducing MacWavelets v2.00
MacWavelets v2.00 is an inexpensive, simple, standalone, Macintosh program for
performing 1d and 2d discrete wavelet transforms and associated analyses.
Version 2.00 of the MacWavelets software includes the 2-d discrete wavelet
transform, its inverse, and all associated compression, denoising, and other
functions. With MacWavelets v2.00 you can:
- 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.
- Sort, truncate, and unsort coefficients.
- Compress and expand data.
- Remove noise from data.
- Extract and insert data subsets.
- 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
MacWavelets v2.00 is currently available for downloading.
On-line User's Manual
The complete MacWavelets v2.00 User's Manual is available on-line. Browse
through this manual to get an idea of the capabilities of this program, and its
ease of operation, before you download the software.
Download the MacWavelets v2.00 Software
Click to download any of the following files:
These files are binhex-encoded self-extracting archives. Once downloaded,
decode the .hqx file (I use Stuffit) and then
double-click on the .sea archive to expand it.
For some reason, you may need to copy the .sea file from
one folder to another before it will open as a double-clickable application.
Don't ask me why, just try this if you get the "Can't open this document etc..."
message from the Finder.
Unfortunately, this site is limited to 200 Mb of downloading per day. You
may get a message saying that the site has exceeded its limit for the day. If
you get this message, or cannot access the file, please try downloading again
License the Software
The initially downloaded MacWavelets v2.00 software is for individual evaluation
purposes only. It cannot save files, print, or export data, as these features
are disabled. To unlock these features, you must license the software. You can
purchase a single-user license and unlocking code for the v2.00 software for $25
(includes free upgrade to v2.10 license). See section
1.5 Security and Licensing
of the on-line User's Manual for more information.
Internet Mailing List
There is an Internet mailing list which is devoted to the MacWavelets
software and its users. To receive updates concerning the software, to ask
questions about the software, and to share information and examples with other
users, you can subscribe to this mailing list.

Please make sure your mailing program doesn't insert additional lines (e.g. siglines)
after this line. You will be sent a comfirmation message, to which you must reply,
before you will receive posts on this list.
