LDAC yog dab tsi?
LDAC yog lub wireless audio coding technology tsim los ntawm Sony. Nws yog thawj zaug nthuav tawm ntawm 2015 CES Consumer Electronics Show. Thaum lub sijhawm, Sony tau hais tias LDAC thev naus laus zis tau ua haujlwm tau zoo peb zaug ntau dua li tus qauv Bluetooth encoding thiab compression system. Nyob rau hauv txoj kev no, cov ntaub ntawv siab daws teeb meem yuav tsis tshaj-compressed thaum wirelessly kis tau tus mob, uas yuav zoo heev upgrade lub suab zoo.
Thaum xa LPCM lub suab daws teeb meem siab, LDAC thev naus laus zis tswj nws qhov siab tshaj plaws me ntsis qhov tob thiab cov lus teb ntau zaus, ua kom muaj kev sib kis tau zoo txawm tias ntawm 96kHz / 24bit suab. Nyob rau hauv sib piv, cov tsoos Bluetooth suab kis tau tus mob technology, ua ntej xa LPCM suab, thaum hloov cov ntaub ntawv suab, thawj yam uas yuav tsum tau ua yog "degrade" lub high-resolution video mus rau ib tug CD zoo ntawm 44.1 kHz / 16 ntsis, thiab ces xa nws. los ntawm 328 kbps, uas yuav ua rau ntau cov ntaub ntawv poob, rau TWICE. Uas yuav ua rau qhov xaus no: qhov kawg suab zoo yog deb tshaj qhov qub zoo ntawm CD.
Tab sis, feem ntau cov thev naus laus zis no tsuas yog siv tau rau Sony cov khoom siv xwb.
AptX yog dab tsi?
AptX yog tus qauv suab codec. Tus qauv yog kev koom ua ke nrog Bluetooth A2DP stereo audio transmission raws tu qauv. Cov tsoos Bluetooth tso suab suab coding tus qauv yog: SBC, feem ntau hu ua narrowband coding, thiab aptX yog tus qauv coding tshiab qhia los ntawm CSR. Raws li qhov xwm txheej ntawm SBC encoding, Bluetooth stereo lub suab xa tawm ncua sij hawm yog siab dua 120ms, thaum tus qauv aptX encoding tuaj yeem pab txo qis latency mus rau 40ms. Qhov ncua sij hawm uas tib neeg feem ntau tuaj yeem hnov thaum lub latency siab dua 70ms. Yog li, yog tias tus qauv aptX tau txais, tus neeg siv yuav tsis hnov qhov kev ncua sijhawm ntawm kev siv tiag tiag, ib yam li kev paub ntawm kev saib TV ncaj qha nrog pob ntseg liab.
Feasycom, raws li ib qho ntawm cov kev daws teeb meem zoo tshaj plaws Bluetooth, tau tsim peb qhov nrov Bluetooth modules nrog aptX, aptX-HD technology. Thiab lawv yog:
Lwm zaus thaum koj tab tom nrhiav kev daws teeb meem rau koj qhov project audio wireless, tsis txhob hnov qab mus NUG FEASYCOM kom pab!
