Yuav ua li cas yog lub suab card?

Tam sim no computer suab phaib tau los ua ib tug paub kev tivthaiv nyob rau hauv computer systems. Muaj ntau novice neeg siv tsis txawm paub hais tias muaj tej zaum yuav muaj ib co lwm txoj kev. Tab sis tsuas yog ib kaum tsib lub xyoos dhau los, txhua txhua computer tswv, leej twg xav hnov qhov kev pab cuam tsis squeak hais lus system, thiab qhov tiag lub suab (thiab txawm lub suab ntawm cov neeg nyob rau hauv multimedia daim ntaub ntawv!), Tau yuam mus yuav lub suab adapter. Ntxiv mus, txoj kev tshawb no ntawm lub suab phaib yuav tsum tau DMA raws thiab cuam tshuam configuration hauv paus ntsiab lus, cov kev xaiv raws li qhov chaw tos tsheb loj tsis nyob rau hauv lub tshuaj cov ntaub ntawv. Nyob rau hauv tas li ntawd, cov thawj qauv nqi kim heev. Raws li ib tug tshwm sim, lub suab phaib tau ntsia tau rau hauv xwb enthusiasts. Thiab dab tsi yog qhov teeb meem no tam sim no?

constructive Solutions

Tag nrho cov uas twb muaj lawm lub suab phaib yuav tau muab faib mus rau hauv peb lub ntsiab hom:

• Discrete qauv. Tej zaum nws yuav tsum tau hu ua classic. Qhov no daim ntawv yog ib tug me me PCB nrog muab tso rau nws nyob rau hauv lub tshuab hluav taws xob Cheebtsam thiab ib pab pawg neeg ntawm zawv zawg hu mus txuas rau qhov kev tsim nyog motherboard tsheb npav connector. Txij li thaum lawv ntsia tau rau hauv lub system unit, lawv tej zaum hu ua nrog;
• Embedded (onboard, kev). Xws li ib tug qauv yog soldered mus rau lub motherboard chipset thiab ob peb koom haum pab piping hais, uas ua rau tag nrho cov yooj yim zog ntawm lub classical suab card;
• Sab nraud. Cov feem ntau yuav pab kiag li lawm yuav tsum tau kev cob cog rua rau lub USB ports.

Nta ua-nyob rau hauv kev daws teeb meem

Heev feem ntau cov neeg tsuas remotely colliding nrog lub nuances ntawm computer suab, cov lus nug tshwm sim txog lub tswv yim sib txawv nyob rau hauv suab phaib. Tom qab tag nrho, tag nrho cov tib yam, qauv nta, tsis yog cov tseem ceeb sib txawv. Cov tsawg kawg yog kim kev daws teeb meem hais ua-nyob rau hauv maps. Qhov tiag tus nqi ntawm lub suab nti yog los ntawm 1 mus rau $ 10 (rau kev sib piv, tus yau nyob rau hauv txoj kab ntawm discrete suab card Asus Xonar manufacturers muaj yuav luag $ 40). Nyob rau hauv tas li ntawd, first-class suab paub hais tias vim cov uas kaw ntom nti arrangement ntawm Cheebtsam ntawm lub motherboard inevitably tshwm sim kev sib nrig sib hluav taws xob interferences uas cuam tshuam rau "kev coj dawb huv" kev ua si. Txawm tias qhov no yuav daws tau los ntawm xa me nyuam rov analog zis rau digital, tus tom kawg yog tsis tsim nyog mus thov ib tug zoo xws li cov pheej yig phaib. Thiab thaum kawg, peb yuav tsum nco ntsoov hais tias feem ntau ntawm cov neeg ua haujlwm ua kwj ua tsav tsheb rau koj daim card suab siv lub hwj chim ntawm lub CPU. Yog li, lub built-in daim ntawv yog ib tug zoo tshuaj rau ib tug neeg uas tsis xav kom siv cov nyiaj rau cov purchase ntawm ib tug nyias muaj nyias ib lub suab adapter, thiab tsis xav txog nws tus kheej ib tug yeej muaj tseeb music lover.

Nuances ntawm discrete qauv

Tam sim no, feem ntau cov kev daws teeb meem rau PCI-Express tsheb npav. Tej maps, txawm lub nqi nruab nrab, twb muaj "rau board" ib tug tag nrho-fledged siab processor uas ua cov ntaub ntawv txaus ua offload. Feem ntau discrete qauv muaj ntau ntau txoj kev xaiv (piv txwv li, ASIO yug) tshaj li tus ua-nyob rau hauv counterparts. Suab zoo yog feem ntau npaum li cas siab tshaj hais tias ntawm lub onboard daws teeb meem. Thaum xaiv, tsum paub hais tias tej yam ntxiv card hauv cov ntaub ntawv worsens cua kev, uas rhuav tshav kub. Nyob rau hauv tas li ntawd, lub hwj chim noj yog siab tshaj hais tias ntawm lub built-nyob rau hauv maps.

Sab nraud suab phaib

Cov pab kiag li lawm yuav tsum tau muab faib ua ob pawg: cov pheej yig, nyob rau hauv qhov tseeb, sawv cev rau tib lub nti li nyob rau hauv lub onboard kev daws teeb meem, tab sis "zaum" nyob rau lub USB tsheb npav; raws li zoo raws li high-end kev phaib.
