Bluetooth Audio Codec ke eng
Bluetooth audio codec e bua ka theknoloji ea audio codec e sebelisoang phetisong ea molumo oa Bluetooth.
Li-codecs tse tloaelehileng tsa Bluetooth
Li-codec tse tloaelehileng tsa Bluetooth 'marakeng li kenyelletsa SBC, AAC, aptX, LDAC, LC3, joalo-joalo.
SBC ke codec ea mantlha ea molumo e sebelisoang haholo ho li-headsets tsa Bluetooth, libui le lisebelisoa tse ling. AAC ke audio codec e sebetsang hantle haholo e sebelisoang haholo lisebelisoa tsa Apple. aptX ke theknoloji ea codec e ntlafalitsoeng ke Qualcomm e fanang ka boleng bo holimo ba molumo le latency e tlase bakeng sa lisebelisoa tsa boleng bo holimo tsa Bluetooth. LDAC ke theknoloji ea codec e entsoeng ke Sony, e ka tšehetsang phetisetso ea molumo o phahameng ho fihlela ho 96kHz/24bit, 'me e loketse lisebelisoa tsa molumo tse phahameng.
Mmaraka oa Bluetooth audio codec o ntse o hola ha tlhoko ea bareki ea molumo oa boleng bo holimo e ntse e eketseha. Nakong e tlang, ka ho ata ha theknoloji ea 5G le ntlafatso e tsoelang pele ea theknoloji ea Bluetooth, 'maraka oa Bluetooth audio codec o tla ba le tebello e pharaletseng ea ts'ebeliso.
LC3 Bluetooth audio codecs
Har'a tsona, LC3 ke theknoloji ea codec e entsoeng ke SIG[F1] , e ka fanang ka boleng bo phahameng ba molumo le tšebeliso e tlase ea matla. Ha ho bapisoa le codec ea khale ea SBC, LC3 e ka fana ka litefiso tse holimo, tse hlahisang boleng bo holimo ba molumo. Ka nako e ts'oanang, e ka boela ea finyella tšebeliso e tlaase ea matla ka tekanyo e lekanang, e thusa ho lelefatsa bophelo ba betri ea sesebelisoa.
LC3 likarolo tsa tekheniki, ho kenyelletsa:
- 1. Block-based fetola mamelwang codec
- 2. Fana ka mabelo a mangata
- 3. Likarolo tsa foreimi ea tšehetso ea 10 ms le 7.5 ms
- 4. Bophara ba quantization bit ea sampole ka 'ngoe ea molumo ke likotoana tse 16, 24 le 32, ke hore, bophara ba data ea PCM.
- 5. Sekhahla sa sampole sa tšehetso: 8 kHz, 16 kHz, 24 kHz, 32 kHz, 44.1 kHz le 48 kHz
- 6. Tšehetsa palo e sa lekanyetsoang ea likanale tsa molumo
LC3 le LE Audio
Theknoloji ea LC3 ke karolo e tšehetsang lihlahisoa tsa LE Audio. Ke maemo a phetiso ea molumo ho thekenoloji ea matla a tlase a Bluetooth. E tla ts'ehetsa li-codec tse ngata tsa audio ho fana ka boleng bo holimo ba molumo le tšebeliso e tlase ea matla.
Ho phaella moo, LE Audio e boetse e tšehetsa mekhoa e meng ea theknoloji ea codec, ho akarelletsa le AAC, aptX Adaptive, joalo-joalo. Litheknoloji tsena tsa codec li ka fana ka boleng bo botle ba molumo le ho fokotsa latency, ho thusa ho ntlafatsa tshebetso le phihlelo ea mosebedisi ea lisebelisoa tsa molumo oa Bluetooth.
Ka bokhutšoanyane, LE Audio e tla tlisa likhetho tse ngata tsa theknoloji ea codec bakeng sa lisebelisoa tsa audio tsa Bluetooth, e le ho fihlela litlhoko tsa basebelisi ba fapaneng bakeng sa boleng ba molumo le tšebeliso ea matla.
LE Audio Bluetooth Module
Feasycom e boetse e hlahisa limmojule tsa Bluetooth tse thehiloeng ho theknoloji ea sehlahisoa sa LE Audio. Ka ho lokolloa ha lihlahisoa tse ncha tse kang BT631D le BT1038X, li ka fana ka boleng bo botle ba molumo le tšebeliso e tlaase ea matla, hape li na le mesebetsi le likarolo tse ngata. Khetho e ntle ea ho theha lisebelisoa tsa audio tsa Bluetooth.
