Kodi Bluetooth Audio Codec ndi chiyani
Bluetooth audio codec imatanthauza ukadaulo wa audio codec womwe umagwiritsidwa ntchito potumiza mawu a Bluetooth.
Common Bluetooth audio codecs
Ma codec omveka a Bluetooth pamsika akuphatikizapo SBC, AAC, aptX, LDAC, LC3, ndi zina.
SBC ndi codec yoyambira yomvera yomwe imagwiritsidwa ntchito kwambiri pamutu wa Bluetooth, okamba ndi zida zina. AAC ndi audio codec yapamwamba kwambiri yomwe imagwiritsidwa ntchito pazida za Apple. aptX ndi ukadaulo wa codec wopangidwa ndi Qualcomm womwe umapereka mawu abwinoko komanso kutsika kotsika kwa zida zomvera za Bluetooth zapamwamba. LDAC ndi ukadaulo wa codec wopangidwa ndi Sony, womwe utha kuthandizira kufalitsa kwamawu mpaka 96kHz/24bit, ndipo ndi yoyenera pazida zomvera zapamwamba.
Msika wa Bluetooth audio codec ukupitilira kukula pomwe kufunikira kwa ogula kumawu apamwamba kukukulirakulira. M'tsogolomu, ndi kutchuka kwa teknoloji ya 5G komanso kupititsa patsogolo teknoloji ya Bluetooth, msika wa Bluetooth audio codec udzakhala ndi chiyembekezo chogwiritsa ntchito.
LC3 Bluetooth audio codecs
Pakati pawo, LC3 ndiukadaulo wa codec wopangidwa ndi SIG[F1] , yomwe ingapereke khalidwe lapamwamba la audio komanso kugwiritsa ntchito mphamvu zochepa. Poyerekeza ndi ma codec amtundu wa SBC, LC3 imatha kupereka mitengo yapamwamba kwambiri, zomwe zimapangitsa kuti mawu azikhala abwinoko. Nthawi yomweyo, imathanso kugwiritsa ntchito mphamvu zochepa pamlingo womwewo, kuthandizira kukulitsa moyo wa batri wa chipangizocho.
LC3 zaukadaulo, kuphatikiza:
- 1. Block-based convert audio codec
- 2. Perekani maulendo angapo
- 3. Support chimango intervals wa 10 ms ndi 7.5 ms
- 4. The quantization bit wide lachitsanzo chilichonse cha audio ndi 16, 24 ndi 32 bits, ndiye kuti, PCM data bit wide
- 5. Thandizo lachitsanzo: 8 kHz, 16 kHz, 24 kHz, 32 kHz, 44.1 kHz ndi 48 kHz
- 6. Thandizani chiwerengero chopanda malire cha njira zomvera
LC3 ndi LE Audio
Ukadaulo wa LC3 ndiwothandizira pazinthu za LE Audio. Ndi njira yotumizira ma audio muukadaulo wa Bluetooth low energy. Idzathandizira ma codec angapo omvera kuti apereke ma audio abwino komanso kugwiritsa ntchito mphamvu zochepa.
Kuphatikiza apo, LE Audio imathandiziranso matekinoloje ena a codec, kuphatikiza AAC, aptX Adaptive, etc. Matekinoloje a codec awa atha kupereka ma audio abwino komanso kutsika kwapang'onopang'ono, kuthandizira kukonza magwiridwe antchito ndi chidziwitso cha ogwiritsa ntchito zida zomvera za Bluetooth.
Mwachidule, LE Audio ibweretsa njira zambiri zaukadaulo wa codec pazida zomvera za Bluetooth, kuti zikwaniritse zosowa za ogwiritsa ntchito osiyanasiyana pamtundu wamawu komanso kugwiritsa ntchito mphamvu.
LE Audio Bluetooth Module
Feasycom komanso akufotokozera zigawo Bluetooth zochokera LE Audio mankhwala luso. Ndi kutulutsidwa kwa zinthu zatsopano monga BT631D ndi BT1038X, zimatha kupereka mawu abwinoko komanso kugwiritsa ntchito mphamvu zochepa, komanso kukhala ndi ntchito zingapo ndi mawonekedwe. Chisankho chabwino kwambiri chopangira zida zomvera za Bluetooth.
