Yintoni iBluetooth Audio Codec
I-codec ye-Bluetooth ye-odiyo ibhekisa kubuchwepheshe bekhowudi ye-odiyo esetyenziswa kuthumelo lwe-Bluetooth lwe-audio.
Iikhowudi zomsindo zeBluetooth eziqhelekileyo
Iikhowudi zomsindo eziqhelekileyo zeBluetooth kwimarike ziquka i-SBC, i-AAC, i-aptX, i-LDAC, i-LC3, njl.
I-SBC yikhowudi yomsindo esisiseko esetyenziswa ngokubanzi kwii-headsets zeBluetooth, izithethi kunye nezinye izixhobo. I-AAC yikhowudi yomsindo ephezulu esetyenziswa kakhulu kwizixhobo ze-Apple. I-aptX yitekhnoloji ye-codec ephuhliswe yi-Qualcomm ebonelela ngomgangatho womsindo ongcono kunye ne-latency esezantsi yezixhobo ze-audio ze-Bluetooth eziphezulu. I-LDAC iteknoloji ye-codec ephuhliswe ngu-Sony, enokuxhasa ukuhanjiswa kwe-audio ye-high-resolution ukuya kwi-96kHz / 24bit, kwaye ifanelekile kwizixhobo zomsindo eziphezulu.
Imakethi ye-codec yomsindo weBluetooth iyaqhubeka nokukhula njengoko imfuno yabathengi yeaudio ekumgangatho ophezulu iqhubeka nokukhula. Kwixesha elizayo, ngokuthandwa kweteknoloji ye-5G kunye nokuphuculwa okuqhubekayo kobuchwepheshe beBluetooth, imarike ye-codec ye-Bluetooth yomsindo iya kuba nethemba elibanzi lesicelo.
I-LC3 yeekhowudi zeBluetooth zeaudio
Phakathi kwabo, i-LC3 iteknoloji ye-codec ephuhliswe yi-SIG[F1] , enokubonelela ngekhwalithi ephezulu yomsindo kunye nokusetyenziswa kwamandla aphantsi. Xa kuthelekiswa nekhowudi ye-SBC yemveli, i-LC3 inokubonelela ngemilinganiselo ephezulu, ekhokelela kumgangatho ongcono we-audio. Kwangaxeshanye, inokuphinda ifikelele kusetyenziso lwamandla asezantsi ngesantya esincinci esifanayo, inceda ukwandisa ubomi bebhetri yesixhobo.
Iimpawu zobugcisa zeLC3, kubandakanya:
- 1. Ibhloko esekelwe kwi-codec yokuguqula i-audio
- 2. Ukubonelela ngezantya ezininzi
- 3. Inkxaso yexesha lesakhelo se-10 ms kunye ne-7.5 ms
- 4. Ubungakanani besuntswana ububanzi besampulu yomsindo nganye yi-16, 24 kunye ne-32 bits, oko kukuthi, i-PCM yedata bit width.
- 5. Ireyithi yenkxaso yesampula: 8 kHz, 16 kHz, 24 kHz, 32 kHz, 44.1 kHz kunye ne-48 kHz
- 6. Ukuxhasa inani elingenamkhawulo lamatshaneli omsindo
I-LC3 kunye ne-LE Audio
Itekhnoloji yeLC3 luphawu oluxhasayo lweemveliso zeLE Audio. Lumgangatho wothumelo lwe-audio kubuchwepheshe bamandla aphantsi eBluetooth. Iya kuxhasa ii-codecs ezininzi zomsindo ukubonelela ngekhwalithi yomsindo engcono kunye nokusetyenziswa kwamandla aphantsi.
Ukongezelela, i-LE Audio iphinde ixhase nezinye iteknoloji ze-codec, kuquka i-AAC, i-aptX Adaptive, njl. Ezi teknoloji ze-codec zinokubonelela ngekhwalithi yomsindo engcono kunye ne-latency ephantsi, inceda ukuphucula ukusebenza kunye namava omsebenzisi wezixhobo zomsindo zeBluetooth.
Ngamafutshane, i-LE Audio iya kuzisa iinketho zobuchwephesha be-codec kwizixhobo zomsindo zeBluetooth, ukuze kuhlangatyezwane neemfuno zabasebenzisi abahlukeneyo kumgangatho weaudio kunye nokusetyenziswa kwamandla.
LE Audio Bluetooth Imodyuli
I-Feasycom ikwaphuhlisa iimodyuli zeBluetooth ezisekwe kwi-LE Audio yemveliso yobuchwepheshe. Ngokukhutshwa kweemveliso ezintsha ezifana ne-BT631D kunye ne-BT1038X, zinokubonelela ngomgangatho womsindo ongcono kunye nokusetyenziswa kwamandla aphantsi, kunye nemisebenzi emininzi kunye neempawu. Ukhetho oluhle kakhulu lokuphuhlisa izixhobo zomsindo zeBluetooth.
