Sound Blaster X-Fi is a lineup of sound cards in Creative's Sound Blaster series. ==History== The series was launched in August 2005 as a lineup of PCI sound cards, served as the introduction for their X-Fi audio processing chip, with models ranging from ''XtremeMusic'' (lower end), to ''Platinum'', ''Fatal1ty FPS'', and ''Elite Pro'' (top of the range).〔(Creative X-Fi Xtreme Music and X-Fi Elite Pro - TrustedReviews )〕 The top-end ''Elite Pro'' model was aimed at musicians, bundled with the X-Fi external I/O box (offering phono with preamp inputs for turntables, high-impedance input for guitars, inch mic input, headphone output, line-in, and full size MIDI I/O, as well as optical and RCA Coaxial digital inputs and outputs), and remote control. The Platinum and Fatal1ty FPS models both offer a front-panel drive-bay control unit and remote control, while the base model was supplied without any such accessories. All but the top model claimed 109dB signal-to-noise ratio, while the ''Elite Pro'' model uses a higher-end DAC, with 116dB claimed. The bottom two models feature 2 MB standard RAM, while the top models offer 64MB of X-RAM,〔(Creative Labs Sound Blaster X-Fi - Maximum PC )〕 designed for use in games to store sound samples for improved gaming performance. October 2006 saw a minor rebranding: the X-Fi XtremeMusic edition, which was in fact a highly capable gaming card, as it offers hardware decoding and EAX support, was replaced with the XtremeGamer model. The revised model featured half-width PCB, non-gold-plated connectors, optical out instead of the digital out and digital I/O module jack, and lacked the connector for users wishing to purchase a separate X-Fi I/O box. Functionality is otherwise the same. The market segment occupied by the XtremeMusic was moved downwards, with the introduction of the (cheaper) 'Xtreme Audio' and 'Xtreme Audio Notebook' products, which, despite the "X-Fi" label, are the only products in the X-Fi line not using the EMU20K1 chip (CA20K1) and thus lacking the hardware acceleration of 3D sound and EAX sound effects, gaming and content creation features and the I/O extensibility of all the other X-Fi models. The other new product introduced was the X-Fi 'XtremeGamer Fatal1ty Pro', identical in function to the Fatal1ty FPS, but made more affordable by the unbundling of the I/O panel and remote control. The 20K1 chip can use a significant amount of RAM to store sound effects for faster and improved processing, just like the previous E-mu 10K-series and E-mu 8000. This feature, dubbed ''X-RAM'' by Creative and found on the higher-end models in the X-Fi line (the Elite Pro, Fatal1ty and XtremeGamer Fatal1ty Pro Series), is claimed to offer quality improvement through audio processing capability enhancement, in addition to further reduction in host system CPU overhead. In 2007 Consumer Electronics Show, Creative Technology unveiled PCI Express x1 and ExpressCard/34 versions of Sound Blaster X-Fi Xtreme Audio. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sound Blaster X-Fi」の詳細全文を読む スポンサード リンク
