What it is

irrKlang is a cross-platform 2D and 3D sound engine and audio library for C++ and .NET development. It plays WAV, OGG, MP3, FLAC, MOD, IT, S3M, and XM files, with both buffered and streamed playback. Its sound capabilities include 3D emulation for low-end hardware, linear or logarithmic rolloff, and effects such as echo, reverb, chorus, and distortion. Developers can use it from C++, C#, VisualBasic.NET, and Delphi.NET. Plugins can extend playback format support, and users can supply their own file readers and decoders. It does not depend on Irrlicht, so it can be used in projects without that engine. irrKlang runs on Windows, Linux, and macOS. It is free for non-commercial products; commercial use requires a Pro license. Listed one-time Pro options start at €65 for individuals and products sold for less than €20, with higher plans for other commercial uses. Linux requires ALSA, and 64-bit systems require matching 64-bit versions. Downloads are available only to existing licensees.
