Monga mukudziwira, mtundu wamawu, kuchedwa kwa zida zosiyanasiyana za Bluetooth kumatha kukhala kosiyana kwambiri. Chifukwa chiyani? Lero tikupatseni yankho ku funso ili.
Kutumiza kwamtundu wapamwamba wa Bluetooth kumatengera mbiri ya A2DP. A2DP imangotanthauzira ndondomeko ndi ndondomeko yotumizira mauthenga apamwamba kwambiri monga mono kapena stereo pa njira yosagwirizana. Protocol iyi ndi yofanana ndi mapaipi otumizira ma data. Zomwe zimafalitsidwa kudzera pa Bluetooth zimagawidwa m'mitundu iyi molingana ndi kalembedwe kake:
ndi chiyani Mtengo wa SBC
Uwu ndiye mtundu wokhazikika wa kabisidwe wamawu a Bluetooth. A2DP (Advanced Audio Distribution Profile) protocol yovomerezeka yamtundu wa coding. Mulingo wovomerezeka kwambiri ndi 320kbit / s mu mono ndi 512kbit / s munjira ziwiri. Tchipisi zonse zomvera za Bluetooth zithandiziranso mtundu wa encoding iyi.
ndi chiyani AAC
Tekinoloje yoperekedwa ndi Dolby Laboratories, ndi njira yophatikizira yophatikizika kwambiri. IPhone imagwiritsa ntchito mtundu wa AAC pakutumiza kwa Bluetooth. Pakadali pano, zida zomvera za Apple za Bluetooth zimagwiritsa ntchito ukadaulo wa encoding wa AAC. Ndipo zida zambiri zolandila monga ma Bluetooth speaker / mahedifoni pamsika zimathandiziranso kutsitsa kwa AAC.
ndi chiyani Zamgululi
Ndi CSR's patented coding algorithm. Itatha kupezedwa ndi Qualcomm, idakhala ukadaulo wake waukulu wolembera. Amanenedwa polengeza kuti imatha kukwaniritsa ma CD. Mafoni ambiri atsopano a Android ali ndi APTX. Ukadaulo wamakodi womverawu ndiwothandiza kwambiri kuposa ma Bluetooth akale, ndipo kumvera kumamveka bwino kuposa ziwiri zam'mbuyomu. Zipangizo zomwe zimagwiritsa ntchito ukadaulo wa APTX ziyenera kufunsira chilolezo kuchokera ku Qualcomm ndikulipira mtengo wololeza, ndipo ziyenera kuthandizidwa ndi njira zotumizira ndi zolandila.
ndi chiyani APTX-HD
aptX HD ndi mawu omveka bwino, ndipo mtundu wamawu ndi wofanana ndi LDAC. Zimatengera mtundu wa aptX wakale, womwe umawonjezera mayendedwe kuti athandizire mtundu wa audio wa 24 bit 48KHz. Ubwino wa izi ndi kutsika kwa ma sign-to-noise komanso kusokoneza pang'ono. Pa nthawi yomweyi, chiwerengero cha kufalitsa chikuwonjezeka kwambiri.
ndi chiyani APTX-LL
aptX LL ndiyotsika-latency, chofunikira kwambiri ndikuti imatha kupeza latency yochepera 40ms. Tikudziwa kuti malire a latency omwe anthu angamve ndi 70ms, ndipo kufika 40ms zikutanthauza kuti sitingamve kuchedwa.
ndi chiyani LDAC
Uwu ndi ukadaulo wamawu wopangidwa ndi SONY, womwe umatha kufalitsa zomvera zamtundu wapamwamba (Hi-Res). Ukadaulowu umatha kufalitsa kuwirikiza katatu kuposa umisiri wina wokhotakhota kudzera pakusunga bwino komanso kusungitsa bwino Deta. Pakadali pano, ukadaulo uwu umangogwiritsidwa ntchito pazida zotumizira ndi kulandira za SONY zokha. Chifukwa chake, zida za SONY zokha zotumizira ndi kulandira zomwe zimathandizira ukadaulo wamawu wa LDAC zitha kugulidwa kuti zithandizire kutumiza kwa data yomvera ya Bluetooth ya LDAC.
Feasycom idapereka mayankho angapo omwe amathandizira mawonekedwe a APTX. Zomwe mungawapeze pansipa:
Mukuganiza bwanji pazachiyambi chachikulu cha 6 Bluetooth Audio Formats? Khalani omasuka kutumiza kufunsa kuti mumve zambiri. Zikomo powerenga nkhaniyi.
