At this time I don't have any formal documentation written for the
encoder package, so here's a quick howto:
=====================================================================
******** E N C O D E R S ********************************************
=====================================================================
There are 2 encoders in each package, one for mono files, the other
for stereo.
Licenced version:
=================
wav2znd.exe is the mono version.
wav2znds.exe is the stereo version.
Evaluation version:
===================
w2zmfree.exe is the mono version.
w2zsfree.exe is the stereo version.
They are DOS programs that take command line arguments to operate.
The wav files must be 16 bit signed (mono or stereo depending on which
encoder you are using) format.
There are 9 quality levels, each with different bandwidth requirements.
speed code sampling rate name description
=====================================================================
0 5500hz mono 14.4low poor music good voice
1 7333hz mono 14.4high acceptable music
2 11025hz mono 28.8low good music
3 14666hz mono 28.8high very good music
4 22050hz mono ISDN nearly perfect music
5 5500hz stereo 28.8low poor music
6 7333hz stereo 28.8high acceptable music
7 11025hz stereo ISDNlow good music
8 14666hz stereo ISDNhigh very good music
If you run wav2znd or wav2znds with no command line, it will give you
a short help screen on how to use it.
The basic format is:
wav2znd filename speed_code
Not that filename does not get the .wav extension. It already knows to
look for a wav file.

To create a drop file, there is a utility called makezdt.exe .
The command line for makezdt is:
makezdt your.ip.add.ress /path/to/file/filename.znd
This will create a file called renameme.zdt . You will need to rename it
with as filename.zdt .
Example:
You have a .ZND file called singing.znd. You put the file in a directory
on your web site called sounds. The command line you would run is:
makezdt 111.222.111.111 /sounds/singing.znd
then
rename renameme.zdt singing.zdt
After that put singing.zdt and singing.znd in /sounds on your server.
The link on your HTML document would be something like:
<a href="http://www.mysite.com/sounds/singing.zdt">Girl Singing</a><br>
When someone clicks on "Girl Singing" they will get the zdt file which
the player reads, connects to your site and plays singing.znd .
Sounds terrible, but it works <grin>.
One thing you will need to have setup on the server is the MIME type for the
zdt files. The MIME type we use is /application webzound-drop for file
extensions zdt and zdat. If you are on a leased server, you may have to get
the admin to add that for you.
In some rare cases a server will need to be told that the ZND files are
binary. This is also done with a MIME type (/application webzound-znd).
You can spot this with every playback erroring out with a decompression
error (the server stripped 8 bits down to 7).

GOLDWAVE is a wav editor which I suggest be used because of its excellent
quality. Also since I use it myself, I can help you with it if you have
problems.
You can download GOLDWAVE from our website. The URL to reach the download
page is:

Disclaimer requested by the Author of GOLDWAVE:
The GOLDWAVE package is not a part of WebZound. This is a functional
evaluation version. See the documentation for more information.
