This is documentation for maplay3 version 1.1 (maplay 1.2 with Layer III support).
Note, that you should also have original maplay documentation files
(ANNOUNCEMENT, INSTALL and README), which may not be up to date for
all features.
Maplay3 should work on most supported unix platforms, but I could test it only
on Linux and IRIX. Since original maplay source was so old it may need
minor tweaking before it works.
usage: maplay [option(s)] [filename(s)]
filename filename of a MPEG audio stream or - for stdin
-v verbose mode
-q quiet mode (don't print filenames, when playing multiple files)
-s write pcm samples to stdout
-l decode only the left channel
-r decode only the right channel
-c check for filter range violations
-f ushort use this scalefactor instead of the default value 32768
-@ list get files (and comments) from file 'list'
-a randomize list order
You may specify more than one input filename (and use wildcards), use
file(s) containing list of files to play or combination of both.
List file format:
Any blank lines or lines with '#' or ';' as first character are ignored.
In any other line, first word is taken as filename and rest of the line
is regarded as comment (and if '-q' switch is not used, printed to screen
when starting to play that file). Filenames may include paths (which are
not printed when playing file). Below is an example of a playlist.

Sources:
Should be in the same package with this file or in same directory
where you got the package this file was in.
Problems?
* If you hear snaps during playback, try adding '-c' parameter. If it suggests
-f switch with a value, use it. (I usually use parameters -c -f 25000)
* If you have trouble compiling maplay3, try GNU C++ (g++) if possible.
* If you have playback problems with your unix workstation, try dumping
decompressed audio stream to standard output ('-s' switch) and piping it
to some other player to see if it works. I can't help with other unix
platforms (unless you are willing to donate me one ;-), so you have to
fix the problem yourself. If you do, please send the fix back to me so
I can add it to next version of maplay3.
Bugs:
For some reason, if linux version is compiled with '-O3' but without
'-ggdb' switch it crashes when playing multiple files (gcc 2.7.2.1).
Report any other bugs to me (timo.jantunen@hut.fi or jeti@cc.hut.fi),
but it has something to do with playback on some unix platform, I
probably can't help.
Legal stuff:
This program is free. You are also free to use or not to use it, but I'm
not responsible of any damage it may cause (and I'm a student so I don't
have money anyway). Do NOT make money with this program (this includes
putting it to a CD-ROM which costs over 30 USD), change copyright
information or distribute it without unmodified files README, README.L3
and COPYING. You should distribute complete sources but if you distribute
precompiled binary with those three files then you need to have complete
sources available somewhere where anyone who got the binary can get it.
