Maplay 1.2+ for Win32

Web Site

Last modified: December 16, 1997

Newest version released: 1.A

Latest News:

FINALLY!!! Version 1.A is now available for Win32, which has much better playlist support. Playlist items can have lyrics or images associated with them, and they can be moved from one computer to another without any difficulty. You can now create these playlists using the player itself. Also there are a lots of other features that have been added. See the file whatsnew.txt for a complete description of the changes.

I will try to finish the DLL, but no promises.

I'll be working in Japan hopefully, but I'll continue work on maplay.

Version 1.81 has been ported to Linux, Macintosh (on PowerPC), OS/2, BeOS, HP-UX, and FreeBSD successfully. For the newest source files and information on these ports, check the ports section.

Alas, I have found out that the console version does not work with Windows 3.1. Sorry for the inconvenience.

The layer III decoder of maplay is highly optimized from the original public c source, but still is quite CPU intensive. If you are interested in making optimizations (and getting a share of the glory) please don't bother with the following functions, which I've already gotten optimizations for:

Optimizations for any other functions are welcomed. Send them to!

What is maplay 1.2?

Maplay 1.2 is a program written for UNIX systems by Tobias Bading. What it does is decodes MPEG Audio Layer I and II files, which are factor of 6-12 times smaller than uncompressed audio (like Windows PCM WAVE, Sun AU, or Apple AIFF files). Despite the huge compression, there is no audible signal loss! Using MPEG Audio Layer III, you can retain CD-quality sound at compression ratios around 1:11 (112 kbit/s). Unfortunately, decoding MPEG audio streams is a very CPU intensive process. And until now, there have been no fully-featured decoders available for Windows.

What is maplay 1.2+ for Win32?

Thanks to Bading's hard work in maintaining portability in maplay, I was able to re-target maplay to run on the Windows 95 and Windows NT operating systems. I also added a few features such as WAV playing, pausing, stopping, and repeating MPEG audio playback. It took about 4 weeks, since I had no prior Windows programming experience. Now after a year of work, maplay 1.2+ for Win32 also has support for layer III MPEG-1 audio streams.

What do I need to run maplay 1.2+ for Win32?

Maplay 1.2+ for Win32 requires the following hardware and software to run:

What about the competition?

Alhough it was the first freeware player for Win32 and many other platforms,  maplay 1.2+ has been becoming less popular nowadays. There are several reasons for this. Many other players are faster. WinAmp has a nice graphical equalizer display. However, with version 1.A, the player has, in my humble opinion, the best features out of any other player out there. Some things maplay 1.2+ does that most other players do not :

What kind of interface does the program have?

Cool. Where can I get maplay for Win32, and how do I install it?

Maplay for Win32, version 1.A, is available here (on my shell account on cory, a Berkeley EECS server) in following four flavors:
486  Pentium 
InstallShield Setup 
No Installshield 
A few notes on installing: These are the NEWEST versions (1.A), last modified on December 16, 1997. See the "whatsnew.txt" file for details on the changes.

The console version (1.90) is also available here in two flavors:

486  Pentium 
These command-line versions (about 83 KB) do not include source code; for the source, please download one the GUI versions. Please see the above note for non-Intel CPU's.

How do I use maplay for Win32?

Maplay for Win32 supports command-line playback, so you can associate MP2, MP3, or MPG files with maplay in the File Manager of Windows Explorer. Actually, this will now be partially done by the installation program, so you don't have to do anything yourself. Just select the MP2 (MPEG-1 Layer II Audio Stream) or LST (playlist) file in Explorer, and double-click! If you want to associate MP3 files to maplay, you will have to do this manually. Just delete whatever association you had before, and double-click on the MP3 file. Use maplay to open the file from now on.You can also use it as a viewer in Netscape. The MIME type is "audio", and the subtype is "x-mpeg". Finally, you can use as a stand-alone program, as there is a menu item to open files. Feel free to e-mail me if you need further instructions.

You can use the playlist editor in maplay 1.2+ to create, edit, and save playlists. You can also associate images and lyrics with each item using the Properties... button in the playlist editor.

How much does maplay for Win32 cost?

Nothing. Well, almost nothing. Of course you still have to pay for the access time and the long distance charges to download it! However, your generous donations are welcomed but not required. To donate, please send a check or money order to:

I'm an extremely poor college student, so anything I receive will go towards my college education. I do also take donations of the form of interesting CD's, anime CD's, videos, posters, cels, etc., or pretty much anything else. If you're not sure I want it, just e-mail me before you send it. Thanks.

Also, if you would like some publicity for your company (a link on this web page and in the About box of the application, something to the effect of "Developed with ... courtesy of ..."), I'd be glad to accept :

I'm also open to donations of other types of hardware or software. In any case, if you are interested in making a donation, please e-mail me. Thank you!

Are there any bugs in maplay 1.2+ for Win32?

Well, as I said before, I'm new at Windows programming, so I'm sure there are. But the following are the only bugs I know about: I'll work on getting rid of these bugs, and if you find any others, please e-mail me.

Where can I get MPEG audio files?

Check out my list of MPEG Audio links.

How do encode my own MPEG audio files?

You can use Cool Edit 96 (with the MPEG audio extensions) or AMPEG 4.3, which is a DOS program, but considerably faster. (AMPEG now decodes Layer III files) Also required is the the source that contains the tables. Remember, before WAV files are encoded, they must be saved in 16-bit format, with a 32 kHz or above sampling frequency. 

How do I obtain or port maplay 1.2+ for other platforms?

The source is much more portable, so it should be relatively easy to compile. The rows of this table that have links indicate that maplay has already been ported, and you can obtain an executable. The rows that are marked "N/A" are ports that haven't been done yet, but should be relatively straightforward (all the code is already written -- the only things left to do are compiling and linking).

I don't want to take away from the authors of SoundApp for the Macintosh and maplay for Linux and OS/2; SoundApp supports a ton of audio formats besides MPEG Audio. maplay3 for Linux and OS/2 have playlist functionality, which the pure command-line version lacks.

The source code for the non-Win32 versions is in the file which doesn't have those nasty ^M characters. Thanks to Gyorgy Kenez for his conversion utility.

Please see my porting notes for information on how to port to these and other platforms.


Want to contribute? Right now, I need a man page for the UNIX versions, a HLP file for the Win32 GUI versions, and some interface code to display characters and numbers nicely (not using fonts). If I use your stuff, I'll be sure to mention you!

I wish to thank the following donators, whose contributions make developing maplay worth the effort:

The Future

New playlist capabilties, a new interface, and Netscape plug-in functionality are planned.

The latest version of maplay is very portable, so I am waiting for people to port the code to many other operating systems. I'd like to see a version for DOS.
