QSMP3 is a MP3 Playback component for Delphi and Kylix. It allows you to add full MP3 playback capabilities to your application under both Win32 and Linux. It is a non-visual component, so it should be functional under Linux CLI, X11, Win32 GUI, and Win32 (not DOS) CLI. Supported capabilities include playback, stop, pause, seek-by-time-index,seek-by-byte-indes, automatic position reporting (by event), and position reporting by function call. This component relies on SDL, SMPEG, and the JEDI-SDL translation of the SDL and SMPEG headers to Pascal.

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.
