Los Iifowuni zeBluetooth Ayiyonguqulelo enkulu yenkulungwane yethu, kodwa simele sivume ukuba yenze ubomi bethu balula kancinane. Kwaye kukuba, nangona ii-headsets ezineentambo zazingenakusilela, kwakungekho mnandi ncam ukuchitha imizuzu emininzi ukhulula amaqhina ngaphambi kokuba ukwazi ukumamela ingoma. Ingqikelelo ethi 'Inyaniso engenacingo' ilapha ukuhlala, kodwa ii-headphones zisenemiba emininzi elindileyo, njengoko kunjalo team, la ukuhla komgangatho okanye ukungahambelani kwekhowudi.
Ngaba ii-headphones ezineentambo zingcono kuneBluetooth?
Kungabonakala ngathi bubuxoki, kodwa kungakhathaliseki ukuba iteknoloji iqhubela phambili kangakanani, kukho izisombululo ezivela kwixesha elidlulileyo eziqhubeka zigqithisa izinto eziqanjiweyo zangoku. Kukho iintlobo ezininzi kunye noluhlu lwee-headphones ezingenazingcingo, kodwa ekusebenzeni, phantse akukho mkhondo womculo owuphulaphulayo kunye nesinye sezi zixhobo ziya kudlula umgangatho esele sinawo ngeCD yasentsomini.
Ii-headphones ezinocingo zazilinganiselwe ekusasazeni amaza omatshini ukusuka kwikhadi lesandi lomdlali ukuya ezindlebeni zethu. Kwi susa intambo kwi-equation, yintoni ekufuneka ihambe ukusuka kwiselfowuni yakho ukuya kwi-headset yi-electromagnetic wave. Emva koko, olo lwazi kufuneka luguqulwe kwisixhobo esincinci osifakileyo endlebeni yakho. Lowo ngumsebenzi weDAC. Kodwa le nto ayipheleli apho. Ukuya Dlulisa idatha eninzi ngexesha lokwenyani usebenzisa iBluetooth, iyimfuneko cinezela ulwazi. Kule nto, abantu abadumileyo basetyenziswa iikhowudi. Aba bamva banoxanduva lokuba kunokubakho umsantsa phakathi kwento oyidlalayo kunye nento oyimameleyo, kunye nengcaciso yokuba kutheni ii-AirPods zivakala ngcono kwi-iPhone kunefowuni ye-Android.
ukubambezeleka ngumba
Uthenga ii-headphones ezintsha kwaye uzame ngefowuni yakho. Bakulungele ukumamela iSpotify okanye enye ipodcast. Kodwa ngenye imini, uye wafumanisa ukuba uthotho olubukeleyo kwiNetflix aluhambisani nesandi. Le ngxaki yenzeka kancinci nangaphantsi, njengoko iteknoloji ihambela phambili. Nangona kunjalo, kunokwenzeka ukuba kuye kwenzeka kuwe kwaye ufuna ukwazi ukuba kukho nayiphi na indlela sombulula le ngxaki into ecaphukisayo xa ubukele iimuvi, uthotho okanye iividiyo zikaYouTube.
Loo msantsa owubonayo phakathi kwemilebe yothetha-thethwano kunye nento oyivayo ngoyena udumileyo latency. Ixesha elinjalo lihlala likhona, nangona sisebenzisa iintambo. Ukubambezeleka kulinganiswa nge Imilisecond, kwaye ayibonakali ngokupheleleyo xa uhamba kumaxabiso aphantsi. Nangona kunjalo, xa i-latency iphezulu, amava okuphulaphula angonakaliswa ngokupheleleyo.
iikhowudi
I-headset nganye ixhasa inani le iikhowudi. Okufanayo kuya kwisixhobo ngasinye oza kusisebenzisa njengomthombo womsindo. Kukho ii-codecs ezingcono kwaye ezimbi, kodwa eyona nto ibalulekileyo ukwazi ukuba iseti yentloko kunye nesixhobo sokudlala kufuneka sixhase ikhowudi enye. Ngokukodwa xa sithetha ngezixhobo eziphezulu. Ukwazi ii-codecs kubalulekile ukuze ukwazi ukufumana okuninzi kwimveliso nganye kwaye ugweme i-latency eyoyikisayo.
SBC
Lo mgangatho wenziwa ngo-1993, kwaye nguye ubuncinane bekhowudi ye-codec ekufuneka ixhaswe nasiphi na isixhobo se-Bluetooth. Isebenzisa iprofayile yomsindo ye-A2DP. Icala elisezantsi le codec kukuba ukucinezelwa kwayo kunokuphuculwa kakhulu. Ifikelela kumlinganiselo ophezulu we I-328 kbps, kwaye ukuncipha kwakhe sisithende sakhe sase-Achilles.
AAC
Yayiluphuhliso lweenkampani ezininzi, phakathi kwazo i-AT&T, iNokia kunye ne-Sony, ukubala ezimbalwa. Umgangatho wayo womsindo ungcono kune-SBC, kodwa ukubambezeleka kwayo kubi ngakumbi. Iye yathandwa kakhulu ngenxa ye-Apple kunye neYouTube. Nangona ingumgangatho omdala, iye yaphucuka kwiminyaka, ngakumbi kwicandelo lokuhanjiswa kwamacingo.
Kule codec sinokubandakanya i I-LD-AAC kunye neentlobo zayo, yileyo isetyenziswa nguApple kwii-AirPods zayo. Okwangoku, uninzi lweengxaki zalo zantlandlolo zisonjululwe ngenxa yokuvela kwayo, kwaye kunokuthiwa ikhowudi ekwaziyo ukujongana neyona iphambili kwicandelo.
I-Sony LDAC
Oku enye yezona codecs eziphambili esinayo ngoku. Yingcaciso yokuba kutheni ii-headphones ezingenazingcingo zolu phawu zidume njengoko zinjalo. Ineentlobo ezintathu:
- I-LDAC 330kbps
- I-LDAC 660kbps
- I-LDAC 990kbps
IQualcomm aptX
Le codec yaqala ukuphuhliswa kwi-80. Ngo-2015, i-Qualcomm yayithatha ukuze iphuhlise. Bafumene ezahlukeneyo ezintathu:
- Ukubambezeleka okuphantsi: nge-aptX LL eyahlukileyo. Ixhasa ireyithi malunga ne-30 ms.
- Inkcazo ephezulu: kunye ne-aptX HD eyahlukileyo. Le codec yenzelwe ukumamela umculo. Ukubambezeleka kunikelwa ukunyusa obona mgangatho uphezulu we-bitrate, ibe ngumgangatho ogqitha umgangatho wesandi weCD, ukwazi ukunyuka ukuya kuma-576 kbps kwi-24 bit kunye ne-192 kHz.
- ikhowudi ye-adaptive: Ikuvumela ukuba utshintshe phakathi kwe-aptX LL kunye ne-aptX HD ngokuxhomekeke kwinto esiyidlalayo, nokuba ufikelele kumaxabiso aphakathi.
I-LDHC (i-Hi-Res Wireless Audio)
Le codec iphuhliswe yi-HWA, kwaye iye ezahlukeneyo ezimbini. Umbutho uxhaswa ziinkampani ezibalulekileyo kwicandelo ezifana neSennheiser, AudioTechnica, Pioneer okanye iHuawei. Icodec iyakwazi ukuhambisa ubuninzi be 900 kbps kwi 24 bit kunye ne 96 KHz nge ukubambezeleka okuphantsi noko.
I-LC3
Ivumela ibitrate phakathi kwe-160 kbps kunye ne-345 kbps phakathi kwe-8 kunye ne-48 kHz kunye ne-latency ephantsi kakhulu. Luphuhliso lwe Iqela elikhethekileyo leBluetooth elinomdla (OKULANDELAYO). Ifakwe ngaphakathi kweBluetooth LE Audio ubuchwepheshe.
Uyilungisa njani imiba ye-latency kwii-headphones zakho zeBluetooth
Ezinye izisombululo ezisebenzayo ukunciphisa ukubambezeleka kwee-headphones zakho Zizo zilandelayo:
Hlaziya iikhowudi kuzo zombini izixhobo
Ngoku uyazi ezona codecs zibalulekileyo phaya, cofa chonga ezo zihambelana nefowuni yakho y iit Iifowuni zentloko.
Ukuba uneselfowuni endala kunye nee-headphone ezintsha, ingxaki ye-latency inokuba ikhona. Hlaziya inkqubo yokusebenza kunye ne-firmware yee-headphones zakho. Injongo yale nkqubo kukuphepha ukusebenzisa eyona codec yamayeza enziwe afana nalawo enziwe ngabenzi bokuqala, ethi, eyona indala, yeyona isebenza kakhulu.
Lungisa kwakhona isixhobo
Ngamanye amaxesha, ingxaki ayikho kakhulu i-codec njengengxaki ethile. Kufuneka udibanise isixhobo kwakhona ukuba ucinga ukuba kukho imiba yoqhagamshelwano okanye ukuba uyaqaphela nje latency kwenye yee-headphones ezimbini.
Kulumkele ukuphazanyiswa
Njengoko sisazi, unxibelelwano ngeBluetooth lubuthathaka kakhulu. Okokuqala, owona mgama uphezulu oqhele ukusebenza kuwo 10 mitha. Nayiphi na imiqobo inokubangela ukungasebenzi kakuhle.
Ukuba sinezixhobo ezithile eziqhagamshelweyo kwaye zisebenzisa iBluetooth, ziyakwazi ukuphazamisa umgangatho. Oku kunokubangela ukuphazamiseka kunye nokwandisa ixesha lokulinda xa umamele isandi.
Ayizizo zonke ii-mobiles kunye nee-headphones ezihambelanayo
Sibuyela kumxholo we iikhowudi. Nawuphi na umenzi we-headphone ofuna ukusebenzisa enye yee-codecs ezimangalisayo esithethe ngazo kwicandelo langaphambili, kufuneka ahambe ngebhokisi-ukuba abanini babo bathengisa iilayisensi, kunjalo. Ezona headphones ziphantsi zixhasa kuphela ii-codecs ezindala. Ukunciphisa i-latency kuya kuba yinto engenakwenzeka. Ngoku uyasiqonda isizathu sokuba ungathenga ii-headphones ezingenazingcingo kwindawo yokuzivocavoca ngee-euro ezilishumi, akunjalo?
Kodwa nathi sinako ingxaki isixhobo sokudlala. Unokuba nee-headphones ezintle kakhulu kunye neselfowuni omenzi wayo engakhange ahlawule iilayisensi zokusebenzisa loo codec. Isiphumo? Iseti yentloko iya kusebenza isebenzisa ikhowudi eyahlukileyo. Ngesi sizathu, ii-AirPods zivakala ngcono kwii-iPhones kunye nee-headphone ze-Sony ziviwa ngokugqibeleleyo kuyo nayiphi na iselula exhasa i-LDAC. Ngeenkqubo, izinto nazo ziyahluka. I-Android ayilawuli kakuhle ii-codecs, kwaye ukungasebenzi kwayo kuyabonakala xa usebenzisa enye ifunwa kakhulu njenge-AAC.
Ngaphambi kokuba uthenge i-headset yeBluetooth, khangela i Iphepha elithile lefowuni yakho kwaye ihlalutya kakuhle ukuba zeziphi iikhowudi ezixhasayo. Emva koko, fumana iperi yee-headphones ezihambelanayo. Ngaphandle koko, isixhobo sakho siya kusebenza kunye nekhowudi engafanelekanga. Kwaye uya kuqaphela kokubili kumgangatho kunye ne-latency.
