a mp3 streamer for the www
Description
m3w is a streamer to stream live audio data to the world-wide-web.
It uses LAME to convert data to mp3 format and can login to an
icecast server to realize an internet radio station. m3w runs under
windows95 or later. m3w is free software.
General News
M3w got a companion program: wimp3, an mp3 player based on a
newly developed mp3 decoder mp32pcm. The later piece of software
is described in great detail in my new book
Understanding MP3 - Syntax, Semantics, Mathematics, and Algorithms
with its own homepage.
Download
The latest version of m3w can be downloaded from the
download page.
M3W Online Manual
Thanks to Adam Hyde, there is a great online manual available
for m3w under
http://www.flossmanuals.net/M3W
.
News for Version 2.3
m3w now supports a UDP streaming mode and can handle input with 48kHz
sample frequency.
News for Version 2.2
This is mostly a bug-fix version. In addition, the handling of output files
was slightly improved. You can now just press the record button, and m3w will
do what you expect it to do.
News for Version 2.1
WARNING: The file setup.exe containing version 2.1
that was posted here between Monday, May 8, 2006, 17:30 GMT
and Thursday, May 11, 2006, 15:25 GMT
contained a serious memory leak. The version that is posted here now
does not contain this bug.
The buffer management has been rewritten.
A autoname feature was added, to generate automatic filenames
from date and time. A bug in the options code was fixed, which
caused trouble in the japanese version. The output file is now
written in shared read mode so that you can read and play the output file
while it is still written.
News for Version 2.0 JA
A Japanese version of m3w was provided by
Kotaro
Thanks a lot. Unfortunately, I do not know any Japanese and I am unable to
fully appreciate the translation.
It can be found on the
download page.
News for Version 2.0 FR
A Translation of m3w to French was provided by
Pierre-Emmanuel Muller.
Merci!
Here are the differences:
- Texts in m3w are translated into French.
- An "Uninstall" link was added in the M3W program folder in the startup menu.
- HTTP is now the default authentification process
as it is the one used by Icecast2.
- If you wonder about Pierre-Emmanuel Muller, who did
the translation, you find hints in the licence file and in the "About" box.
The French version can be found on the
download page.

History of Previous Versions
News for Version 1.7
- The RECORD button was a bit dangerous: You press it and your outputfile is
truncated to zero (removing all these precious bits from your harddisk), unless
of course the append box was checked. Now, the appened box is checked by default
and you will get a warning message with the option to press OK, if you really
want to ..., or CANCEL otherwise.
- Your can store the setting of your append box in the configuration file.
- Storing your average-, variable-, constant-bitrate configuration, did not
work with 1.6. Now there is a new option: --bitmode (short -M), that will do it.
The options cbr, abr and pre do no longer exist (sorry).
News for Version 1.6
- The list of command line and configuration file options was completed.
Now you can set any internal parameter using a command line switch or a
configuration file.
- The help file was updated.
- Installing m3w, will create a file association: The program m3w will be
associated with files having the extension m3w, assuming these are configuration
files. If such a file is opend using the context menu or just by double clicking
on it, m3w ist started, the configuration file is passed to it as a command
line argument, causing m3w to load this configuration. That is: You can start
m3w in your favorite configuration just by doubleclicking on the configuration
file.
- Not really new: You can drop a configuration file on m3w using Drag and
Drop, and this will cause m3w to read the configuration file.
News for Version 1.5
- The Peak level meter for the sound input got a new clipping indicator.
- The help file was not found the first time help was invoked. Now
WinHelp gets a little hint where to look for.
- The Help file got updated. (not too many people seem to read it, but
believe me, its quite good).
News for Version 1.4
- Major Bug fixed in Buffer allocation code for output buffers.
- Default size of output buffers increased to 20s due to tests
with several providers of dial-up connections.
News for Version 1.3
- Some bugs fixed concerning the encoder parameters
in Average Bitrate Mode and with Presets.
News for Version 1.2
- can write ID3 version 1.1 tags.
- more robust defaults (minimum and maximum bitrate).
- comes with Lame version 3.91 encoding library
