Nytt lydkort fra Creative! Soundblaster Zenith

[Goodall]

Kom over noe artig på mike's hardware .

 

Creative Soundblaster Zenith is expected to be released in May. The successor to the Audigy series, Zenith will be a PCI Express x1 solution based around a completely redesigned architecture.

 

Dette høres jo spennende ut, og at det er ventet å bli lansert i mai er jo litt spennende

Jøss! Creative er kjappe med PCI Express i så fall.

 

Lydkortbransjen er forholdsvis konservativ (det er få lydkort med USB2, f.eks.) så jeg hadde trodd det skulle gå litt lenger. Men forhåpentligvis vil andre ta etter.

Zenith will be a based around a completely redesigned architecture - the first major architectural overhaul since the EMU10K introduced with the SBLive!. The key component in Zenith is Creative's X-Fi chip, which features 51 million transistors and operates at a clock speed of 400Mhz with 10,340 MIPS of processing power (compared with the EMU10K2.5 of the Audigy2 ZS which features 4.6 million transistors running at 200Mhz and giving around 420 MIPS of processing power). The chip is divided into five cores, connected together by Creative's Audio Ring bus, which routes data between the cores and provides access to the on-board 2-64MB of SDRAM, the PCI bus and the I/O ports. The Tank core is a digital delay engine, providing reverb, chorus, inter-aural time delay and reflections, relinquishing the CPU or DSP from having to perform these operations. The SRC core is dedicated to Sample Rate Conversion. The majority of this processing power in X-Fi is dedicated to this core. The core is designed to reduce the inter modulation distortion to almost lossless levels when performing SRC (e.g. converting between 44.1 and 48Khz audio). The X-Fi chip also features the Filter core, which is an optimized, fixed function filter engine, providing hundreds of digital filters for environmental modeling, positional audio, music synthesis, and audio customization. The Mixer core scales, sums and reroutes the data from the other processing cores, and the final DSP core (Quartet) is a SIMD programmable processor providing both time and frequency domain signal processing. Time domain effects (such as reverb) are regularly used for adding environmental effects, but few frequency domain effects are currently used due to the large processing overhead. The DSP is used with Creative's "Active Premium Audio" system, which can create centre and surround channel information from a two track recording to provide multi channel sound, improve the quality of audio given your particular speaker system and listening environment and even enhance compressed audio content such as MP3/WMA/AAC to improve it's dynamic range.

 

Gleder meg til tester av dette kortet

Dette var spennende, får se hvordan resulatatet blir når tester begynner å dukke opp.
