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
