Welcome to the kX Project

The kX Project is an independent development project, focused on providing free WDM Audio Drivers for kX-Compatible sound cards. Read our Mission statement for a quick introduction.

The kX Audio Driver is an independent WDM (Windows Driver Model) driver for all EMU10K1 and EMU10K2-based soundcards manufactured by Creative Technology Ltd. and/or E-mu Systems Inc., including the SoundBlaster Live! series, the E-mu Audio Production Studio (APS) card, and the Audigy / Audigy2 series of cards. (Full List).

The kX Audio Driver package includes driver system files and setup files as well as a powerful audio mixer application (the kX Mixer), which acts as a Graphical User Interface, providing access to many of the driver's internal functions. The following features are either fully supported or partially supported in the latest release of the kX Audio Driver:

  • Wave Recording & Playback
  • MIDI Synthesizer (Soundfont-based) and MIDI UART In/Out
  • DirectSound 2D and DirectSound 3D
  • Full ASIO and GSIF support
  • DSP Microcode Loading/Unloading
  • Full AC97 codec control
  • AC3 Software Decoding

The kX Driver is FREE and will remain FREE. Please note that you can always encourage development by making a donation to the kX Fund. As one of our contributors has pointed out, if all satisfied kX users made even a very modest donation (say $10 each), it would go a long way towards deferring our costs and would further encourage development of new features (and elimination of old bugs).
