Example using irrKlang in C++

This C++ example code shows how to play an mp3 file:

#include <iostream>
#include <irrKlang.h>
using namespace irrklang;

int main(int argc, const char** argv)
{
  // start the sound engine with default parameters
  ISoundEngine* engine = createIrrKlangDevice();

  if (!engine)
    return 0; // error starting up the engine
 
  // play some sound stream, looped
  engine->play2D("somefile.mp3", true);

  char i = 0;
  std::cin >> i; // wait for user to press some key

  engine->drop(); // delete engine
  return 0;
}

This code works on all supported platforms (currently Windows, Linux and MacOSX). For more examples and information about using irrKlang in C++, take a look at the irrKlang C++ API documentation.

Example using irrKlang in C#

The following example was written in C# and shows how to play an mp3 file:

using IrrKlang; 

namespace HelloWorld
{
  class Example
  {
   [STAThread]
   static void Main(string[] args)
   {
     // start up the engine
     ISoundEngine engine = new ISoundEngine();

     // play a sound file
     engine.play2D("somefile.mp3");

     // wait until user presses ok to end application
     System.Windows.Forms.MessageBox.Show(
	 	 	 "Playing, press ok to end.");

   } // end main()

  } // end class

} // end namespace
