In their own words
irrKlang
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.
Reactional Engine
Reactional Engine is a framework for generating music note by note in games and changing it as gameplay unfolds. It uses virtual instruments rather than loop-based systems, with controls for key, scale, tempo, and instrumentation. The engine can interpolate, modulate, improvise, and randomize musical elements. It can analyze commercial tracks for tempo and harmony to synchronize generated music and support transitions between generated and commercial material. Unity and Unreal Engine integrations are available; Wwise and FMOD integrations are described, while Godot is listed as coming soon. Runtime targets include Windows, macOS, Linux, iOS, Android, WebGL, PlayStation 4/5, Xbox, and Nintendo Switch. API examples cover transport controls, musical settings, stinger triggers, and callbacks for bars, beats, and notes. Windows and macOS binaries are available through the Reactional Platform. Developers can test any track for free and pay on release. Commercial music licensing is described with worldwide perpetual rights, and interactive themes start at $75 per track. Pricing is on request for Studio; Free access is listed at free.
