irrKlang is a high level 2D and 3D cross platform sound engine and audio library that plays WAV, MP3, OGG, MOD, XM, IT, S3M, and other file formats. It can be used by C++ and all .NET languages (C#, Visual Basic.NET, etc.). It has all of the features common to low-level audio libraries as well as lots of useful features like a sophisticated streaming engine, extendable audio reading, single and multi-threading modes, 3D audio emulation for low-end hardware, a plugin system, multiple rolloff models, sound effects, and more. All of these can be accessed via an extremely simple API using an object oriented design.

IrrXML is a high speed and easy-to-use XML parser without external dependencies. It is very small and provides forward- only, read-only access to a stream of non-validated XML data through an extensible object oriented interface. It ideally fits into realtime projects which need to read XML data without overhead, like games.
