+// This example will show how to play sounds using irrKlang.
+// It will play a looped background music and a sound every
+// time the user presses a key.
+
+// At the beginning, we need to include the irrKlang headers (irrKlang.h) and
+// the iostream headers needed to print text to the console.
+
+#include <stdio.h>
+#include <irrKlang.h>
+
+// include console I/O methods (conio.h for windows, our wrapper in linux)
+#if defined(WIN32)
+#include <conio.h>
+#else
+#include "../common/conio.h"
+#endif
+
+// Also, we tell the compiler to use the namespaces 'irrklang'.
+// All classes and functions of irrKlang can be found in the namespace 'irrklang'.
+// If you want to use a class of the engine,
+// you'll have to type an irrklang:: before the name of the class.
+// For example, to use the ISoundEngine, write: irrklang::ISoundEngine. To avoid having
+// to put irrklang:: before of the name of every class, we tell the compiler that
+// we use that namespaces here.
+
+using namespace irrklang;
+
+// To be able to use the irrKlang.dll file, we need to link with the irrKlang.lib.
+// We could set this option in the project settings, but to make it easy we use
+// a pragma comment:
+
+#pragma comment(lib, "irrKlang.lib") // link with irrKlang.dll
+
+// Now lets start with irrKlang 3D sound engine example 01, demonstrating simple 2D sound.
+// Start up the sound engine using createIrrKlangDevice(). You can specify several
+// options as parameters when invoking that function, but for this example, the default
+// parameters are enough.
+int main(int argc, const char** argv)
+{
+	// start the sound engine with default parameters
+	ISoundEngine* engine = createIrrKlangDevice();
+
+	if (!engine)
+	{
+		printf("Could not startup engine\n");
+		return 0; // error starting up the engine
+	}
+
+	// To play a sound, we only to call play2D(). The second parameter
+	// tells the engine to play it looped.
+
+	// play some sound stream, looped
+	engine->play2D("../../media/getout.ogg", true);
+
+	// In a loop, wait until user presses 'q' to exit or another key to
+	// play another sound.
+
+	printf("\nHello World!\n");
+
+	do
+	{
+		printf("Press any key to play some sound, press 'q' to quit.\n");
+
+		// play a single sound
+		engine->play2D("../../media/bell.wav");
+	}
+	while(getch() != 'q');
+
+	// After we are finished, we have to delete the irrKlang Device created earlier
+	// with createIrrKlangDevice(). Use ::drop() to do that. In irrKlang, you should
+	// delete all objects you created with a method or function that starts with 'create'.
+	// (an exception is the play2D()- or play3D()-method, see the documentation or the
+	// next example for an explanation)
+	// The object is deleted simply by calling ->drop().
+
+	engine->drop(); // delete engine
+	return 0;
