Yonke into omawuyazi malunga ne-LE Audio

Yintoni LE Audio?

I-LE Audio ngumgangatho omtsha weteknoloji yomsindo owenziwe yiBluetooth Special Interest Group (SIG) ngo-2020. Isekelwe kwiBluetooth low-energy 5.2 kwaye isebenzisa i-ISOC (isochronous) architecture. I-LE Audio yazisa i-algorithm ye-LC3 ye-codec ye-audio, enikezela nge-latency ephantsi kunye nomgangatho ophezulu wokuhambisa. Ikwaxhasa iimpawu ezinjengokunxibelelana kwezixhobo ezininzi kunye nokwabelana ngeaudio, ukubonelela abathengi ngamava omsindo aphezulu.

Izinto eziluncedo ze-LE Audio xa kuthelekiswa ne-Classic Bluetooth

Ikhowudi yeLC3

I-LC3, njenge-codec enyanzelekileyo exhaswa yi-LE Audio, ilingana ne-SBC kwi-audio ye-Bluetooth yakudala. Ikulungele ukuba yikhowudi ye-codec yexesha elizayo yeBluetooth. Xa kuthelekiswa ne-SBC, i-LC3 ibonelela:

• Umlinganiselo oPhakamileyo weCompression (uLatency esezantsi): I-LC3 ibonelela ngomlinganiselo ophezulu woxinzelelo xa kuthelekiswa ne-SBC kwi-audio yeBluetooth yakudala, ekhokelela ekubambeni okuphantsi. Kwidatha ye-stereo kwi-48K / 16bit, i-LC3 ifezekisa umlinganiselo ophezulu wokunyaniseka we-8: 1 (96kbps), ngelixa i-SBC isebenza nge-328kbps kwidatha efanayo.
• Umgangatho ongcono wesandi: Kwakwi-bitrate efanayo, i-LC3 igqwesa i-SBC kumgangatho we-audio, ngakumbi ekuphatheni amaza aphakathi ukuya-phantsi.
• Inkxaso yeeFomathi zeAudiyo ezahlukeneyo: I-LC3 ixhasa ukwahlukana kwesakhelo se-10ms kunye ne-7.5ms, i-16-bit, i-24-bit, kunye ne-32-bit yesampulu yomsindo, inani elingenamkhawulo lamatshaneli e-audio, kunye neesampuli ze-8kHz, 16kHz, 24kHz, 32kHz, 44.1kHz kunye ne-48kHz.

Ii-Audio zoMjezo omninzi

• Inkxaso yeeMijelo ezininzi eziZimeleyo, eziNxibeleniswayo: I-audio ye-multi-stream yenza ukuhanjiswa kwe-audio ezininzi ezizimeleyo, ezilungelelanisiweyo phakathi kwesixhobo somthombo wesandi (umzekelo, i-smartphone) kunye nesixhobo esinye okanye ezininzi zokufumana i-audio. Imowudi eqhubekayo ye-Isochronous Stream (CIS) iseka amandla aphantsi e-Bluetooth ACL uxhulumaniso phakathi kwezixhobo, ukuqinisekisa ukulungelelaniswa kwe-True Wireless Stereo (TWS) kunye ne-low-latency, ukuvumelanisa ukuhanjiswa kwe-audio multi-stream.

Usasazo lwe-Audio Feature

• Ukusasaza iAudio ukuya kwiZixhobo ezingasikelwanga mda: Imowudi ye-Broadcast Isochronous Stream (BIS) kwi-LE Audio ivumela isixhobo somthombo womsindo ukuba sisasaze enye okanye imijelo yomsindo emininzi kwinani elingenamkhawulo wezixhobo zokumkela umsindo. I-BIS yenzelwe iimeko zosasazo oluvakalayo lukawonke-wonke, olufana nokumamela umabonwakude uthe cwaka kwiindawo zokutyela okanye izibhengezo zikawonke-wonke kwizikhululo zeenqwelomoya. Ixhasa ukudlala okudityanisiweyo okudityanisiweyo kwisixhobo ngasinye esifumanayo kwaye yenza kube lula ukukhetha imijelo ethile, njengokukhetha ingoma yolwimi kwindawo yethiyetha. I-BIS ayilungelelaniswanga, igcina utshintshiselwano lwedatha, inciphisa ukusetyenziswa kwamandla, kwaye ivula amathuba amatsha ebekade engenakufikelelwa ngokusetyenziswa kweBluetooth yakudala.

Unyino LE Audio

I-LE Audio ineengenelo ezinjengomgangatho weaudio ephezulu, ukusetyenziswa kwamandla aphantsi, i-latency ephantsi, ukusebenzisana okunamandla, kunye nenkxaso yonxibelelwano oluninzi. Nangona kunjalo, njengetekhnoloji entsha, nayo inemida yayo:

• Imiba yokuNhambelana kweSixhobo: Ngenxa yobuninzi beenkampani kushishino, ukubekwa emgangathweni kunye nokwamkelwa kwe-LE Audio ijongene nemingeni, ekhokelela kwimicimbi yokuhambelana phakathi kweemveliso ezahlukeneyo ze-LE Audio.
• Iingxaki zokuSebenza: Ukuntsokotha okuphezulu kweLC3 kunye neLC3 kunye ne-codec algorithms kubeka iimfuno ezithile kumandla wokwenza itshiphu. Ezinye iitshiphusi zinokuxhasa iprothokholi kodwa zizabalazele ukuphatha inkqubo yokufaka ikhowudi kunye nenkqubo yokubhalwa kwekhowudi ngokufanelekileyo.
• Izixhobo ezixhaswayo eziNcinane: Okwangoku, kukho izixhobo ezimbalwa ezixhasa i-LE Audio. Nangona iimveliso zeflegi ezivela kwizixhobo eziphathwayo kunye nabavelisi be-headphone sele beqalisile ukwazisa i-LE Audio, ukutshintshwa ngokupheleleyo kusaza kufuna ixesha. Ukujongana nale ndawo yentlungu, i-Feasycom iye yazisa ngokutsha imodyuli yokuqala yehlabathi yeBluetooth exhasa zombini iLE Audio kunye neClassic Audio ngaxeshanye, ivumela uphuhliso olutsha lwe-LE Audio ukusebenza ngaphandle kokuphazamisa amava omsebenzisi we-Classic Audio.

Usetyenziso lwe-LE Audio

Ngokusekwe kwiingenelo ezahlukeneyo ze-LE Audio, ngakumbi i-Auracast (esekwe kwimowudi ye-BIS), inokusetyenziswa kwiimeko ezininzi zeaudio ukuphucula amava omsindo wabasebenzisi:

• Ukwabelana ngeAudiyo kobuqu: Ukusasazwa kwe-Isochronous Stream (BIS) ivumela enye okanye ngaphezulu imijelo yomsindo ukuba kwabelwane ngayo ngenani elingenamkhawulo wezixhobo, okwenza abasebenzisi babelane ngesandi sabo kunye nee-headphones zabasebenzisi abakufutshane besebenzisa ii-smartphones okanye iitafile zabo.
• Ukumamela okuPhuculo/okuNcedisayo kwiNdawo zoLuntu: I-Auracast ayincedi kuphela ukubonelela ngokusasazwa ngokubanzi kubantu abangeva kakuhle kunye nokuphucula ukufumaneka kweenkonzo zokuphulaphula ezincedisayo kodwa yandisa ukusetyenziswa kwezi nkqubo kubathengi abanamanqanaba ahlukeneyo okuva.
• Inkxaso yeeLwimi ezininzi: Kwiindawo apho abantu beelwimi ezahlukeneyo bahlanganisana khona, njengamaziko enkomfa okanye imiboniso bhanyabhanya, i-Auracast inokubonelela ngokuguqulela ngaxeshanye ngolwimi lomthonyama lomsebenzisi.
• Iinkqubo zabaKhokeli boKhenketho: Kwiindawo ezinje ngeemyuziyam, amabala emidlalo, kunye nezinto ezinomtsalane kubakhenkethi, abasebenzisi banokusebenzisa ii-earbuds zabo okanye ii-headphones ukumamela ukhenketho lwemithombo yomsindo, bebonelela ngamava antywilayo ngakumbi.
• Izikrini zeTV ezithuleyo: I-Auracast ivumela abasebenzisi ukuba baphulaphule i-audio evela kwi-TV xa kungekho sandi okanye xa ivolumu iphantsi kakhulu ukuva, ukuphucula amava kwiindwendwe kwiindawo ezifana neendawo zokuzivocavoca kunye nemivalo yezemidlalo.

IiNdlela ezizayo ze-LE Audio

Ngokweziqikelelo ze-ABI zoPhando, ngo-2028, umthamo wonyaka wokuthunyelwa kwezixhobo ze-LE Audio ezixhaswayo ziya kufikelela kwi-3 yezigidi, kwaye ngo-2027, i-90% yee-smartphones ezithunyelwa ngonyaka ziya kuxhasa i-LE Audio. Ngaphandle kwamathandabuzo, i-LE Audio iya kuqhuba inguqu kuyo yonke intsimi ye-audio ye-Bluetooth, idlulela ngaphaya kokuhanjiswa kwe-audio yemveli kwizicelo kwi-Intanethi yezinto (IoT), amakhaya ahlakaniphile, kunye nezinye iindawo.
