high level audio engine

irrKlang is a cross platform sound library for C++, C# and all .NET languages.

It is free for non-commercial use. The commercial version is named 'irrKlang pro' and has pricing schemes ideal for independent developers.

irrKlang is a high level 2D and 3D cross platform (Windows, macOS, Linux) sound engine and audio library which plays WAV, MP3, OGG, FLAC, MOD, XM, IT, S3M and more file formats, and is usable in C++ and all .NET languages (C#, F#, 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++

#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
   static void Main(string[] args)
     // start up the engine
     ISoundEngine engine = new ISoundEngine();

     // play a sound file

     // wait until user presses ok to end application
	 	 	 "Playing, press ok to end.");

   } // end main()

  } // end class

} // end namespace

For more examples and information about using irrKlang in .NET languages like C#, VisualBasic, Delphi.NET and similar take a look at the irrKlang .NET API documentation.
