irrKlang

irrKlang is a cross platform audio library designed to be used in games, scientific simulations and similar.

It is a high level 2D and 3D cross platform (Windows, Mac OS X, Linux) sound engine and audio library which plays WAV, MP3, OGG, MOD, XM, IT, S3M and more file formats, and is usable in C++ and all .NET languages (C#, VisualBasic.NET, etc). It has all the features known from low level audio libraries as well as lots of useful features like a sophisticated streaming engine, extendable audio reading, single and multithreading modes, 3d audio emulation for low end hardware, a plugin system, multiple rolloff models and more. All this can be accessed via an extremely simple API.

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
