NAME

       SDLx::Sound - SDL sound extension

CATEGORY

       Extension

SYNOPSIS

	   use SDLx::Sound;

	   my $snd = SDLx::Sound->new();

	   # loads and plays a single sound now
	   $snd->play('myfile.wav');

	   # load a single file
	   $snd->load('theSound.aif');

	   # plays it or all loaded files
	   $snd->play();

	   # more sounds
	   my %files = (
	       channel_01 => "/my_sound1.wav",
	       channel_02 => "/my_sound2.ogg"
	   );

	   # times sounds bangs
	   my %times = (
	       channel_01 => 0,      # start
	       channel_01 => 1256,   # milliseconds
	       channel_02 => 2345
	   );

	   # Load files in channels for realtime play
	   $snd->load(%files);

	   # sets sound channel_01 loudness
	   $snd->loud('channel_01', 80);       # loud at 80%
	   $snd->play(%times);		       # play loaded files at times
	   $snd->play;			       # play again

	   # plays sound channel_01 at 578 milliseconds from now
	   $snd->play('channel_01', 578);

	   # fades sound
	   $snd->fade('channel_02', 2345, 3456, -20);

	   # in a single act do the whole Sound
	   my $snd = SDLx::Sound->new(
	       files => (
		   channel_01 => "/my_sound1.wav",
		   channel_02 => "/my_sound2.ogg"

	       ),
	       loud  => (
		   channel_01 => 80,
		   channel_02 => 75
	       ),
	       times => (
		   channel_01 => 0,	 # start
		   channel_01 => 1256,	 # milliseconds
		   channel_02 => 2345
	       ),
	       fade  => (
		   channel_02 => [2345, 3456, -20]
	       )
	   )->play();

DESCRIPTION

       You can think about the SDLx::Sound at 2 approaches.

       o   A simple sound or

       o   The sound of your game or app.

       Your application will say what the best approach.

       In a taste that resembles to perl and to SDL, our SDLx:Sound hooks at SDL::Audio and SDL::Mixer with a graceful and simple interface that
       can offer to monks a modern perlish way to manage sounds.

       An SDLx::Sound object can load sounds from filesystem, play it, adjust this loudness level or stops the sound.

       Each sound will play in the next available channel, so it can be handled isolately.

METHODS

   new
       Returns a new instance of SDLx::Sound

   load
   play
	$sdlx_sound->play('file.wav');

       Play a file

   pause
   resume
   stop

SDL Manual
       "SDL::Tutorial" are incomplete and old. A new book has been started to provide a complete tutorial for SDL. See <http://bit.ly/hvxc9V>.

SDL BASICS

       SDL, the Simple DirectMedia Layer, is a cross-platform multimedia library.  These are the Perl 5 bindings.  You can find out more about SDL
       at <http://www.libsdl.org/>. You can find out more about SDL perl at <http://sdl.perl.org>.

       Creating an SDL application with Perl is easy.  You have to know a few basics, though.  Here's how to get up and running as quickly as
       possible.

   Surfaces
       All graphics in SDL live on a surface.  You'll need at least one.  That's what SDLx::App provides.

       Of course, before you can get a surface, you need to initialize your video mode.  SDL gives you several options, including whether to run
       in a window or take over the full screen, the size of the window, the bit depth of your colors, and whether to use hardware acceleration.
       For now, we'll build something really simple.

   Initialization
       SDLx::App makes it easy to initialize video and create a surface.  Here's how to ask for a windowed surface with 640x480x16 resolution:

	       use SDLx::App;

	       my $app = SDLx::App->new(
		       width  => 640,
		       height => 480,
		       depth  => 16,
	       );

       You can get more creative, especially if you use the "title" and "icon" attributes in a windowed application.  Here's how to set the window
       title of the application to "My SDL Program":

	       use SDLx::App;

	       my $app = SDLx::App->new(
		       height => 640,
		       width  => 480,
		       depth  => 16,
		       title  => 'My SDL Program',
	       );

       Setting an icon is a little more involved -- you have to load an image onto a surface.  That's a bit more complicated, but see the "name"
       parameter to "SDL::Surface-"new()> if you want to skip ahead.

   Working With The App
       Since $app from the code above is just an SDL surface with some extra sugar, it behaves much like SDL::Surface.	In particular, the all-
       important "blit" and "update" methods work.  You'll need to create SDL::Rect objects representing sources of graphics to draw onto the
       $app's surface, "blit" them there, then "update" the $app.

       Note:  "blitting" is copying a chunk of memory from one place to another.

       That, however, is another tutorial.
