- maplay 1.2+ for Win32
-
- What's New?
-
- 10/10/96 : Version 1.71
-
- - Installation is now through an InstallShield application. If you want
- the source files, choose the custom installation. Otherwise, just choose
- the typical installation. Also, the MP2 extension is automatically
- associated to maplay, so you don't have to do this yourself.
-
- - Discovered that memory leaks as waveform audio is being played in
- Windows 95. This is not a bug in maplay, but in Windows 95 itself.
- The result is that the allocated memory slowly rises as MPEG and WAV
- files are being played.
-
- - Received Borland C++ 5.01 courtesy of Borland International through
- Mike Weisert. The program now reports that it is a 32-bit 4.0 application
- instead of 32-bit 3.1 application. The MPEG..Options dialog box looks
- much better with 4.0's color scheme. Also there is real Pentium
- optimization.
-
- - Fixed the MPEG..Options dialog box which did not allow the user to
- decode only one channel of stereo streams. This option works as before
- but displays a warning if a stream is being decoded in the background.
-
- - Added the capability to take playlists from the command line. The
- file extension LST is now interpreted as a playlist also. (Before
- playlists had to have the extension TXT.) Now you can have your lists
- play by double-clicking the LST file in Explorer. (InstallShield will
- automatically associate LST files for you.) Also the batch file
- "makelist.bat" creates a file called "playlist.lst" instead of
- "playlist.txt".
-
- - Made the application window larger to accommodate larger fonts.
-
- - Fixed the time per frame for Layer I files. The playback time should now
- be accurate for all layers.
-
- - Memory for the playlists and mpeg objects is now freed correctly. Also
- the current track is now reset when loading new playlists.
-
- 08/01/96 : Version 1.70
-
- - Interface changes:
-
- * Replaced the scrollbar with a trackbar.
- * Added status bar for current action, current file in playlist, current playtime, and
- if Repeat is enabled (an "R" will appear in the rightmost pane).
- * Removed the repeat button for playlists, and placed the previous track and next track
- buttons next to the rewind and fast foward buttons, repectively. The rewind and fast
- forward look like this: << and >>. The previous track and next track buttons look
- like this: |< and >|.
- * Added rewind and fast forward to the Audio menu.
- * The MPEG...Decoding Options dialog box has been changed. The background is now
- light gray, but the text is still black on white. Right now the dialog box looks
- quite ugly, but once I figure out how to get black on light gray text, it will
- look much better.
- * Colored in the play and stop buttons. Added 3D look to disabled buttons.
-
- - Fixed MIDI playback so that MIDI files can also be seeked.
-
- - Widened the application window so that Large Fonts at 1024x768 don't make the
- menu bar wrap around to the next line.
-
- - Included a batch file to make playlists from the command line. Type
- "makelist /?" for instructions.
-
- - Layer III code is already in maplay, but it needs to be debugged. Attempting
- to decode Layer III streams will result in memory access violations. I will
- not include the buggy code for the Layer III stuff in the source code
- version.
-
-
- 07/09/96 (version 1.61)
-
- - Changed the default extension of MPEG audio files from "MP2" to "MP*".
- This will allow more MPEG audio files to be opened easily, and prepares
- for Layer III (MP3) files.
-
- - Fixed a bug which sometimes caused the scroll bar to not be reset after
- playing.
-
- - Changed the MPEG...Decoding Options dialog box back to the ugly default
- Windows dialog box. The Borland style one cannot load unless BWCC.DLL
- is loaded before the application is run, so I took it out.
-
- - Made the libararies link statically, which increases the code size, but
- reduces the possibility that the application will fail to work due to
- missing DLL files. (I think)
-
- - Started work on layer III. Some layer III stuff has been added in the
- source code, but of course, it doesn't work yet.
-
- 06/26/96 (version 1.60)
-
- - Added a scroll bar that updates as sounds play. You can also use it to
- seek anywhere in the sound. Fast forward and rewind also have been
- implemented.
-
- - Reduced the buffer size by one half again, to reduce latency when seeking.
- Again, if you had version 1.51 or earlier working correctly, and version
- 1.60 messes up, just let me know.
-
- - A couple more cosmetic changes, and additions to the maplay classes that
- allow seeks.
-
- - The output buffer now uses fixed memory which is more likely to be available.
-
- - Reduced the size of the executable (from 180 KB to 83 KB) by not including
- debug information.
-
- 03/31/96 : Version 1.51
-
- - Added the ability to play MIDI files. Wow, I'm a genius (NOT). Still,
- it's cool that you can just use maplay to play everything. You can also
- put MIDI files in the playlists.
-
- 03/28/96 : Version 1.50
-
- - Replaced buttons with neat looking icons. 3D too!
-
- - Added ability to stop after pausing playback.
-
- - Added a dialog box to play files in stereo or in mono. This function works
- but the pre-decode feature has not been implemented yet. Selecting mono will
- take half as much CPU time, and may be necessary for 486 or lower CPUs.
-
- - Fixed a minor bug with play lists, but lists still do not play perfectly.
-
- - Made all the buffers of all versions (386, 486, Pentium) the same size. I
- don't think the size of the buffer makes much difference anyway. If you
- had a version that worked before, but doesn't work now, please contact
- me.
-
- - Discovered a minor "bug" - Wave files will not play if you have spaces
- in the filename or the directory that the WAV file is in.
-
- 03/11/96 : Version 1.30
-
- - Added play list functionality. To play a list of files, create a text
- file with a filenames (MP2 or WAV) separated by newlines (hit enter after
- each filename). Make sure you include the full path in the filename, and
- that the name of the list file ends with a TXT extension. Here is a sample
- list (arg.txt):
-
- sucky_american_music.mp2
- grunge_bites.wav
- anime_rules.mp2
- send_donations_to_Jeff-san.wav
-
- The play list is far from perfect, as it frequently freezes in the middle of
- files. I'll work on fixing it.
-
- - Fixed lack of stereo playback. The previous version only played the first
- file in stereo, but after loading a mono file, the playback remained in mono
- for stereo streams. This has been completely fixed.
-
-
- I'll continue to try to improve maplay until it is perfect. Layer III
- decoding is next. Better playlist manipulation, and Netscape plug-in
- functionality are in the plans.
