Ua hoʻokuʻu ʻo Huawei i kahi ʻenehana hou HWA Bluetooth HD ka hoʻouna ʻana i nā leo leo, Me ka maikaʻi o ke kani ʻoi aku ka maikaʻi ma mua o LDAC
codec hoʻoili mele Bluetooth mainstream
ʻO ka poʻe leʻaleʻa mele makemake e hoʻolohe i ke mele a loaʻa nā koi kiʻekiʻe no ka maikaʻi o ke kani, pono e ʻike i ka codec hoʻoili mele Bluetooth mainstream i kēia manawa he SBC, Qualcomm's aptX/aptX HD, Apple's AAC a me Sony's LDAC.
ʻO SBC ka mea i kākoʻo nui ʻia; ʻO Apple AAC kahi ʻaelike paʻa ponoʻī, iTunes hale kūʻai mele a me iOS Bluetooth hoʻoili hoʻoili ʻana ma kahi o 320kbps code rate (iPhone / iPad i kākoʻo wale iā AAC & SBC); Loaʻa iā Qualcomm aptX ka helu helu kiʻekiʻe loa (koi i ka aptX HD) a hiki ke hiki i 576kbps. Eia naʻe, ʻaʻole hiki i ka helu helu kiʻekiʻe loa o ka codec ma luna ke hiki i ka palena liʻiliʻi liʻiliʻi o ka 44.1 kHz/16 bit lossless compression (no ka laʻana, ʻo ka format FLAC ma kahi o 700 kbps). Hiki iā Sony LDAC ke hoʻonui i ka bit rate i 909kbps (e pili ana me 44.1kHz a i ʻole 88.2kHz sampling rate) a i ʻole 990kbps (e like me 48kHz a i ʻole 96kHz sampling rate). Ma ke kumumanaʻo, hiki ke hoʻouna i ka leo kokoke-lossless ma o kahi pilina Bluetooth, i hoʻohālikelike ʻia me ka maikaʻi o ka leo CD. No laila, ʻo ka maikaʻi o ka leo hoʻoili Bluetooth mai ke kiʻekiʻe a haʻahaʻa: LDAC> aptX> AAC> SBC.
He aha ka HWA Bluetooth transmission protocol
ʻO ka inoa piha ʻo HWA ʻo Hi-Res Wireless Audio. ʻO kahi maʻamau maʻamau e pili ana i ka ʻike hoʻolohe o nā mea kūʻai aku ʻaʻole wale e uhi i nā koi hana e like me ke codec, ka uila uila, ka lohi, ka anti-interference, Active noise control, transparent transmission, a me ka hoʻomanawanui, akā noʻonoʻo pū kekahi i nā hōʻailona electroacoustic pahuhopu a me ka maikaʻi o ka leo. ʻaʻole Bluetooth Audio codec. He maʻamau leo uea ʻole wehewehe kiʻekiʻe i hoʻomohala ʻia e Huawei, China Audio Association, a me China Electronics Technology Standardization Research Institute, me ka hui pū ʻana me 30 mau ʻoihana kūloko a me nā ʻāina ʻē. ʻO ia hoʻi ka maʻamau mua i hoʻomohala ʻia e nā mea hana hale e hoʻomaikaʻi i ka hana o ke kani leo Bluetooth. Hoʻokumu ʻia ia ma LDHC codec, ʻoi aku ka maikaʻi ma mua o Qualcomm aptxHD a me Sony LDAC. ʻO nā mea ʻekolu i pili i kahi pae leo maikaʻi, akā ʻoi aku ka maikaʻi o ke kani ma hope o ka hoʻoponopono ʻana o Huawei.
pono o ka ʻenehana HWA
ʻO ka pōmaikaʻi nui loa o ka ʻenehana HWA, ʻaʻole ia e hōʻoia i ka hoʻonā kiʻekiʻe o ka hoʻouna leo uila, e hōʻoia i ka maʻemaʻe kiʻekiʻe o ka maikaʻi o ke kani, akā mālama pū kekahi i kahi mamao hoʻohana maʻamau a me ka ʻike ma lalo o nā kūlana kiʻekiʻe. Ma mua, ʻaʻole hiki i nā headphone kelepona ke hōʻoia i ka maikaʻi o ke kani. E lilo i mea i hala. Eia kekahi, ma ke ʻano he mea hope loa, he laikini manuahi ka HWA; Ua kōkua nui kēia i nā mea hana hale e hana i kahi holomua nui i ka wā e hiki mai ana ke kani uila o nā kelepona paʻalima.
Mahalo iā Huawei no ka hāʻawi ʻana i kēia ʻenehana manuahi, e hoʻemi nā mea hana Bluetooth i ke kumukūʻai o nā patent, a hāʻawi i nā modula leo Bluetooth maikaʻi aʻe i nā hui huahana Bluetooth, e hāʻawi ana i nā mea kūʻai aku me nā mele maikaʻi aʻe. I ka wā e hiki mai ana, e mālama ʻo Feasycom i nā kumukūʻai no nā mea kūʻai aku me ka hāʻawi ʻana i nā modula Bluetooth maikaʻi aʻe i nā mea kūʻai aku, me ka hoʻohana ʻana i ka ʻenehana HWA.
