He aha ka Bluetooth Audio Codec
ʻO ke codec leo Bluetooth e pili ana i ka ʻenehana codec leo i hoʻohana ʻia i ka hoʻouna leo leo Bluetooth.
Nā codec leo Bluetooth maʻamau
ʻO nā codec leo Bluetooth maʻamau ma ka mākeke ʻo SBC, AAC, aptX, LDAC, LC3, etc.
ʻO SBC kahi codec leo maʻamau i hoʻohana nui ʻia i nā headset Bluetooth, nā mea ʻōlelo a me nā mea hana ʻē aʻe. ʻO AAC kahi codec leo kiʻekiʻe i hoʻohana nui ʻia ma nā polokalamu Apple. ʻO aptX kahi ʻenehana codec i hoʻomohala ʻia e Qualcomm e hāʻawi ana i ka maikaʻi leo maikaʻi a me ka latency haʻahaʻa no nā mea leo Bluetooth kiʻekiʻe. ʻO LDAC kahi ʻenehana codec i hoʻomohala ʻia e Sony, hiki ke kākoʻo i ka hoʻouna leo leo kiʻekiʻe a hiki i 96kHz/24bit, a kūpono i nā lako leo kiʻekiʻe.
Ke hoʻomau nei ka ulu ʻana o ka mākeke leo codec Bluetooth i ka piʻi ʻana o ka makemake o nā mea kūʻai aku no ka leo kiʻekiʻe. I ka wā e hiki mai ana, me ka hoʻolaha ʻana o ka ʻenehana 5G a me ka hoʻomau mau ʻana o ka ʻenehana Bluetooth, e loaʻa i ka mākeke leo codec Bluetooth kahi manaʻo ākea ākea.
Nā codec leo Bluetooth LC3
Ma waena o lākou, ʻo LC3 kahi ʻenehana codec i hoʻomohala ʻia e SIG[F1] , hiki ke hāʻawi i ka maikaʻi leo kiʻekiʻe a me ka hoʻohana mana haʻahaʻa. Hoʻohālikelike ʻia i ka codec SBC kuʻuna, hiki i ka LC3 ke hāʻawi i nā pākēkē kiʻekiʻe, e hopena i ka maikaʻi o ka leo. I ka manawa like, hiki iā ia ke hoʻokō i ka hoʻohana haʻahaʻa haʻahaʻa ma ka helu bit like, e kōkua ana e hoʻolōʻihi i ke ola pākaukau o ka hāmeʻa.
Nā hiʻohiʻona ʻenehana LC3, me:
- 1. Block-ma muli hoʻololi leo codec
- 2. Hāʻawi i nā wikiwiki he nui
- 3. Kākoʻo i nā wā o ke kiʻi o 10 ms a me 7.5 ms
- 4. He 16, 24 a me 32 mau bit ka laula o kela ame keia leo, oia hoi ka laula bit data PCM.
- 5. Kākoʻo i ka laʻana laʻana: 8 kHz, 16 kHz, 24 kHz, 32 kHz, 44.1 kHz a me 48 kHz
- 6. Kākoʻo i ka helu palena ʻole o nā kaha leo
LC3 a me LE Audio
ʻO ka ʻenehana LC3 kahi hiʻohiʻona kākoʻo o nā huahana LE Audio. He maʻamau hoʻouna leo ia ma ka ʻenehana ʻenehana haʻahaʻa Bluetooth. E kākoʻo ia i nā codec leo he nui e hāʻawi i ka maikaʻi leo maikaʻi a me ka hoʻohana haʻahaʻa haʻahaʻa.
Eia kekahi, kākoʻo pū ʻo LE Audio i nā ʻenehana codec ʻē aʻe, e like me AAC, aptX Adaptive, etc. Hiki i kēia mau ʻenehana codec ke hāʻawi i ka maikaʻi leo maikaʻi a me ka latency haʻahaʻa, e kōkua ana i ka hoʻomaikaʻi ʻana i ka hana a me ka ʻike mea hoʻohana o nā mea leo Bluetooth.
I ka pōkole, e lawe mai ʻo LE Audio i nā koho ʻenehana codec hou aku no nā polokalamu leo Bluetooth, i mea e hoʻokō ai i nā pono o nā mea hoʻohana like ʻole no ka maikaʻi leo a me ka hoʻohana mana.
LE Audio Bluetooth Module
Hoʻokumu pū ʻo Feasycom i nā module Bluetooth e pili ana i ka ʻenehana huahana LE Audio. Me ka hoʻokuʻu ʻana o nā huahana hou e like me BT631D a me BT1038X, hiki iā lākou ke hāʻawi i ka maikaʻi leo maikaʻi a me ka hoʻohana haʻahaʻa haʻahaʻa, a he nui nā hana a me nā hiʻohiʻona. He koho maikaʻi loa no ka hoʻomohala ʻana i nā leo leo Bluetooth.
