Designed to be an upgrade for the earlier CS4610, their marketing name for the CS462x chips was "CrystalClear SoundFusion PCI Audio Accelerator".
The CS4622 had an embedded 3D position audio compatible with Microsoft DirectX 5.0, built-in wavetable with Fat Labs samples and onboard DSP (digital signal processing), Dolby Digital AC-3 support, and was PC/PCI, DDMA, and CCLS-ready to provide legacy DOS compatibility.
Among other things it provides an "Enhanced Game Port", able to send and receive digital data packets over the game port - designed for joysticks and other devices that require more than the 15-pin analogue game port could traditionally handle.
The CS4624 is a cost-reduced version of the CS4622, with no support for Dolby Digital AC-3 and a reduced clock speed.
