LE Audio ke eng?
LE Audio ke tekanyetso e ncha ea theknoloji ea molumo e hlahisitsoeng ke Bluetooth Special Interest Group (SIG) ka 2020. E thehiloe holim'a Bluetooth low-energy 5.2 mme e sebelisa sebopeho sa ISOC (isochronous). LE Audio e hlahisa mokhoa o mocha oa LC3 audio codec algorithm, e fanang ka latency e tlase le boleng bo phahameng ba phetisetso. E boetse e tšehetsa likarolo tse kang khokahanyo ea lisebelisoa tse ngata le ho arolelana molumo, ho fa bareki phihlelo e phahameng ea molumo.
Melemo ea LE Audio ha e bapisoa le Classic Bluetooth
LC3 Codec
LC3, joalo ka codec e tlamang e tšehetsoeng ke LE Audio, e lekana le SBC ka molumo oa khale oa Bluetooth. E mothating oa ho ba codec ea mantlha bakeng sa audio ea Bluetooth ea nakong e tlang. Ha ho bapisoa le SBC, LC3 e fana ka:
- Higher Compression Ratio (Lower Latency):
LC3 e fana ka tekanyo e phahameng ea compression ha e bapisoa le SBC ho audio ea khale ea Bluetooth, e bakang latency e tlase. Bakeng sa lintlha tsa stereo ho 48K/16bit, LC3 e fihlella tekanyo e phahameng ea khatello ea maikutlo ea 8: 1 (96kbps), ha SBC e sebetsa ka 328kbps bakeng sa data e tšoanang.
- Boleng bo Betere ba Modumo:
Ka mokhoa o ts'oanang oa bitrate, LC3 e feta SBC ka boleng ba molumo, haholo-holo ho sebetsana le maqhubu a mahareng ho isa tlase.
- Tšehetso ea liforomo tse fapaneng tsa molumo:
LC3 e ts'ehetsa linako tsa foreimi tsa 10ms le 7.5ms, 16-bit, 24-bit, le 32-bit audio sampling, palo e sa lekanyetsoang ea liteishene tsa molumo, le maqhubu a sampole a 8kHz, 16kHz, 24kHz, 32kHz, 44.1, 48kHz le XNUMXkHz.
Multi-Stream Audio
- Ts'ehetso bakeng sa Melaetsa ea Molumo e Ikemetseng e Mengata, e Hokahantsoeng:
Molumo oa li-multi-stream o nolofalletsa phetiso ea melapo e mengata e ikemetseng, e hokahaneng pakeng tsa sesebelisoa sa mohloli oa molumo (mohlala, smartphone) le sesebelisoa se le seng kapa ho feta tse amohelang molumo. Mokhoa oa Continuous Isochronous Stream (CIS) o theha likhokahano tsa Bluetooth ACL tse nang le matla a tlase lipakeng tsa lisebelisoa, ho netefatsa hore khokahano ea 'nete ea True Wireless Stereo (TWS) e ntlafala le latency e tlase, phetisetso ea audio ea melapo e mengata.
Phatlalatso ea Audio Feature
- Phatlalatsa Audio ho Lisebelisoa tse sa Lekanyetsoang:
Mokhoa oa Broadcast Isochronous Stream (BIS) ho LE Audio o lumella sesebelisoa sa mohloli oa molumo ho phatlalatsa melaetsa e le 'ngoe kapa tse ngata tsa molumo ho palo e sa lekanyetsoang ea lisebelisoa tse amohelang molumo. BIS e etselitsoe maemo a khaso ea sechaba, joalo ka ho mamela TV ka khutso lireschorenteng kapa liphatlalatso tsa sechaba boemafofaneng. E ts'ehetsa ho bapaloa ha molumo ho sesebelisoa se seng le se seng se amohelang 'me e nolofalletsa khetho ea melapo e ikhethileng, joalo ka ho khetha pina ea puo sebakeng sa libaesekopo. BIS ha e tsamaellane, e boloka phapanyetsano ea data, e fokotsa tšebeliso ea matla, 'me e bula menyetla e mecha eo pele e neng e sa fihlellehe ka ts'ebetso ea khale ea Bluetooth.
Meeli ea LE Audio
LE Audio e na le melemo e joalo ka boleng bo holimo ba molumo, tšebeliso e tlase ea matla, latency e tlase, tšebelisano e matla, le ts'ehetso ea likhokahano tse ngata. Leha ho le joalo, joalo ka theknoloji e ncha, e boetse e na le mefokolo ea eona:
- Mathata a Tšebelisano ea Sesebediswa:
Ka lebaka la bongata ba lik'hamphani tse indastering, maemo le ho amoheloa ha LE Audio ho tobana le mathata, a lebisang mathateng a ho lumellana har'a lihlahisoa tse fapaneng tsa LE Audio.
- Ts'ebetso ea Bottlenecks:
Ho rarahana ho hoholo ha LC3 le LC3 hammoho le li-algorithms tsa codec ho beha litlhoko tse itseng ho matla a ts'ebetso ea chip. Li-chips tse ling li ka ts'ehetsa protocol empa li thatafalloa ho sebetsana le ts'ebetso ea khouto le ea ho decoding hantle.
- Lisebelisoa tse Tšehetsoang tse Lekanyelitsoeng:
Hajoale, ho na le lisebelisoa tse fokolang tse tšehetsang LE Audio. Leha lihlahisoa tsa li-flagship tse tsoang lisebelisoa tsa mehala le baetsi ba li-headphone ba se ba qalile ho hlahisa LE Audio, phetoho e felletseng e ntse e tla hloka nako. Ho rarolla ntlha ena ea bohloko, Feasycom e hlahisitse ka boqhetseke mojule oa pele oa Bluetooth lefatšeng o tšehetsang LE Audio le Classic Audio ka nako e le 'ngoe, e lumellang nts'etsopele e ncha ea tšebetso ea LE Audio ntle le ho sekisetsa boiphihlelo ba mosebelisi ba Classic Audio.
Lisebelisoa tsa LE Audio
E ipapisitse le melemo e fapaneng ea LE Audio, haholo Auracast (e ipapisitse le mokhoa oa BIS), e ka sebelisoa maemong a mameloang a mangata ho ntlafatsa boiphihlelo ba audio ba basebelisi:
