Sound Blaster - Fifth Generation Sound Blasters, PCI Cards, Multi-Channel Sound and F/X - Sound Blaster X-Fi

Sound Blaster X-Fi

The X-Fi (for "Extreme Fidelity") was released in August 2005 and as of 2012 came in XtremeGamer, Titanium, Titanium Fatal1ty Professional, Titanium Fatal1ty Champion and Elite Pro configurations. Since its release, X-Fi caused several unsolved problems with sound glitches on various motherboards. The 130 nm EMU20K1 (or EMU20K2 for Titanium series models) audio chip operates at 400 MHz and has 51 million transistors. . The computational power of this processor, i.e. its performance, is estimated as 10,000 MIPS, which is about 24 times higher than the estimated performance of its predecessor, the Audigy processor. Beginning with the 2008 Titanium models, newer X-Fi cards switched from PCI to PCI Express x1 connectors. With the X-Fi's "Active Modal Architecture" (AMA), the user can choose one of three optimization modes: Gaming, Entertainment, and Creation; each enabling a combination of the features of the chipset. The X-Fi uses EAX 5.0 which supports up to 128 3D-positioned voices with up to four effects applied to each. This release also included the 24-bit crystallizer, which is intended to pronounce percussion elements by placing some emphasis on low and high pitched parts of the sound. The X-Fi, at its release, offered some of the most powerful mixing capabilities available, making it a powerful entry-level card for home musicians. The other big improvement in the X-Fi over the previous Audigy designs was the complete overhaul of the resampling engine on the card. The previous Audigy cards had their DSPs locked at 48/16, meaning any content that didn't match was resampled on the card in hardware; which was done poorly and resulted in a lot of intermodulation distortion. Many hardcore users worked around this by means of resampling their content using high quality software decoders, usually in the form of a plugin in their media player. Creative completely re-wrote the resampling method used on the X-Fi and dedicated more than half of the power of the DSP to the process; resulting in a very clean resample.
