A powerful high level API for playing back sound in 3D and 2D applications.
irrKlang is a powerful high level API for playing back sound in 3D and 2D applications like games, scientific visualizations and multimedia applications. irrKlang is free for non commercial use. There is also an advanced version of irrKlang named irrKlang pro which can be purchased for a small license fee and may be used in commercial products.

irrKlang currently plays back the following file formats:
* RIFF WAVE (*.wav)
* Ogg Vorbis (*.ogg)
* MPEG-1 Audio Layer 3 (*.mp3)[2]
* Free Lossless Audio Codec (*.FLAC)
* Amiga Modules (*.mod)
* Impulse Tracker (*.it)
* Scream Tracker 3 (*.s3d)
* Fast Tracker 2 (*.xm)

irrKlang is able to play short buffered sounds (e.g. gun shots) as well as huge, streamed sounds (e.g. a radio mp3) in 3D. A conversion to mono sounds is not necessary here, irrKlang is able to do this on the fly. Additional 3D features are:
* Fast 3D audio on low end hardware: Because some low end audio hardware is not able to play 3D sounds without significant performance loss or some dont support 3d audio buffers at all, irrKlang has a high performance 3d sound buffer emulator built-in, causing a sound experience nearly as it was a real 3d sound buffer.
* Multiple rolloff models: irrKlang supports linear as well as logarithmic rolloff.

irrKlangs current features are:
* Plays multiple file formats, .WAV, .MP3, .OGG, .MOD, .XM, .IT, .S3M...
* Buffered and streamed audio playback, in 2D and 3D.
* irrKlang is platform Independent: irrKlang runs on several operating systems including Windows 95, 98, NT, 2000, XP, Vista, Linux, Mac OS X (Intel as well as Power PC).
* Incredible simple API
* ophisticated 3D sound engine designed to be used in games.
* Extendable: Possibility to write own file format readers/decoders to extend the engine with it.
* Sound effects such as the Doppler effect for 3D sounds or 2D effects like echo, reverb, distortion, flanger and more. you can free download irrKlang 1.3.0b now.
