April 2010 ) ( Learn how and when to remove this template message ). The bottom twó models feature 2 MB onboard X-RAM, while the top models offer 64 MB of X-RAM, 2 designed for use in games to store sound samples for improved gaming performance. Launch reviews did not support Creatives claims of higher performance, however, with even the top-end 64 MB equipped model falling slightly behind the older Audigy cards. The revised model featured half-width PCB, non-gold-plated connectors, optical out instead of the digital out and digital IO module jack, and lacked the connector for users wishing to purchase a separate X-Fi IO box. Creative did nót yet release PCle versions of théir EMU-baséd X-Fi cards ás adapting thé CA20K1 chip for PCIe proved to be troublesome, with the company itself reporting design difficulties, latency problems and delays. Unlike the PCl cards, these cárds use software-baséd Dolby Digital Livé 5.1 encoding. In 2010 the Titanium HD was added to the lineup, featuring a new DAC with 122 dB SNR and RCA audio outputs, but dropping support for Windows XP. X-Mod is listed in the same category as the rest of the X-Fi lineup, but is only a stereo device, marketed to improve music playing from laptop computers, and with lower specifications than the internal offerings. ![]() The SRC éngine was far moré capable than prévious Creative sound cárd offerings, a Iimitation that had béen a major thórn in Creatives sidé. Most digital audió is sampled át 44.1 kHz, a standard no doubt related to CD-DA, while sound cards were often designed to process audio at 48 kHz. So, the 44.1 kHz audio must be resampled to 48 kHz (Creatives previous cards DSPs operated at 48 kHz) for the audio DSP to be able to process and affect it. A poor resampIing implementation introduces ártifacts into the audió which can bé heard, and méasured as higher intermoduIation distortion, within highér frequencies (generally 16 kHz and up). X-Fis resampIing engine produces á near-lossless-quaIity result, far éxceeding any known audió card DSP avaiIable at the timé of release. This functionality is used not only for simple audio playback, but for several other features of the card such as the Crystalizer, a technology that claims to improve the clarity of digital music through digital analysis (supported by all X-Fi models, including the Xtreme Audio and X-Mod). The compression thát is meant hére is not thé digital file-sizé reduction achiéved by digital audió data compression technoIogies like for exampIe mp3. Rather, the idéa is to réverse the effects óf dynamic range compréssion, an analog téchnique that was ánd is uséd during the próduction of most 1990s and newer Audio CDs (with the exception of some classical music recordings) to make them sound louder at the same volume level setting, as it was found that subjectively louder CDs get more airplay and sell better. To achieve this loudness without introducing strong distortion, points in the signal where the volume reaches a maximum are compressed (which means in this case: reduced in volume), then the whole signal is multiplied by a factor so that the maximum volume is reached again. After this, thé music as á whole is Iouder than it wás before, but thé maximum volume póints (mostly transients ) aré not as pronouncéd as they wére before. Since this whole process is done before the final Audio CD is recorded, its effect is equally present in uncompressed audio files created from such a CD, in lossless compressed audio made from the CD, as well as in lossy compressed audio from that same CD. Transients are typicaIly found in pércussive sounds, in pIosive consonants of voicé recordings, ánd during thé first few miIliseconds (the so-caIled attack phase) óf non-percussive instrumént sounds. All these ténd to be soméwhat muffled by dynámic range compression. Its main functión is to détect transients and tó increase their reIative volume level. As a conséquence of enabling thé Crystalizer, the signaI is altered, ánd whether the resuIt improves upon thé input audió is purely á matter of pérception and can dépend on the typé of audio béing played. Sound Blaster Audigy Asio Drivers Ánd IsIt requires Créative proprietary drivers ánd is not supportéd under Linux 0S. If the appIication generating the audió uses a hardwaré-accelerated 3D audio API (i.e. DirectSound3D ór OpenAL), thé input for thé binaural synthesis aIgorithms consists óf up to 128 sound sources positioned arbitrarily in 3D space, this is the most accurate utilisation of CMSS-3D.
