Iyini i-Bluetooth Audio Codec
I-codec yomsindo ye-Bluetooth ibhekisela kubuchwepheshe bekhodekhi yomsindo obusetshenziswa ekudluliseni umsindo we-Bluetooth.
Amakhodekhi womsindo we-Bluetooth ajwayelekile
Ama-codec ajwayelekile e-Bluetooth emakethe afaka i-SBC, i-AAC, i-aptX, i-LDAC, i-LC3, njll.
I-SBC iyikhodekhi yomsindo eyisisekelo esetshenziswa kabanzi kumahedisethi e-Bluetooth, izipikha namanye amadivaysi. I-AAC iyikhodekhi yomsindo esebenza kahle kakhulu esetshenziswa kakhulu kumadivayisi we-Apple. I-aptX ubuchwepheshe be-codec obuthuthukiswe yi-Qualcomm obuhlinzeka ngekhwalithi yomsindo engcono nokubambezeleka okuphansi kwamadivayisi omsindo we-Bluetooth asezingeni eliphezulu. I-LDAC ubuchwepheshe bekhodekhi obuthuthukiswe ngabakwa-Sony, obukwazi ukusekela ukudluliswa komsindo kwesinqumo esiphezulu kuze kufike ku-96kHz/24bit, futhi ifanele izinto zomsindo ezisezingeni eliphezulu.
Imakethe ye-codec yomsindo we-Bluetooth iyaqhubeka nokukhula njengoba isidingo sabathengi somsindo wekhwalithi ephezulu siqhubeka nokwanda. Ngokuzayo, ngokuduma kobuchwepheshe be-5G kanye nokuthuthukiswa okuqhubekayo kobuchwepheshe be-Bluetooth, imakethe ye-codec yomsindo we-Bluetooth izoba nethuba elibanzi lohlelo lokusebenza.
I-LC3 Bluetooth audio codecs
Phakathi kwazo, i-LC3 ubuchwepheshe be-codec obuthuthukiswe yi-SIG[F1] , enganikeza ikhwalithi yomsindo ephezulu kanye nokusetshenziswa kwamandla okuphansi. Uma kuqhathaniswa nekhodekhi yendabuko ye-SBC, i-LC3 inganikeza amanani ebhithi aphezulu, okuholela kukhwalithi yomsindo engcono. Ngesikhathi esifanayo, ingakwazi futhi ukuzuza ukusetshenziswa kwamandla okuphansi ngezinga elifanayo lebhithi, lisize ukunweba impilo yebhethri yedivayisi.
Izici zobuchwepheshe ze-LC3, kufaka phakathi:
- 1. Ikhodekhi yomsindo esekelwe kubhulokhi
- 2. Nikeza izivinini eziningi
- 3. Sekela izikhawu zozimele ezingu-10 ms no-7.5 ms
- 4. Ububanzi bebhithi yokulinganisa yesampula ngayinye yomsindo yibhithi elingu-16, 24 no-32, okungukuthi, ububanzi bebhithi yedatha ye-PCM
- 5. Izinga lesampula lokusekela: 8 kHz, 16 kHz, 24 kHz, 32 kHz, 44.1 kHz kanye no-48 kHz
- 6. Sekela inombolo engenamkhawulo yamashaneli alalelwayo
I-LC3 ne-LE Audio
Ubuchwepheshe be-LC3 buyisici esisekela imikhiqizo ye-LE Audio. Kuyindinganiso yokudlulisa umsindo kubuchwepheshe bamandla aphansi we-Bluetooth. Izosekela amakhodekhi amaningi omsindo ukuze inikeze ikhwalithi yomsindo engcono kanye nokusetshenziswa kwamandla okuphansi.
Ngaphezu kwalokho, i-LE Audio iphinde isekele obunye ubuchwepheshe be-codec, okuhlanganisa i-AAC, i-aptX Adaptive, njll. Lobu buchwepheshe be-codec bunganikeza ikhwalithi yomsindo engcono kanye nokubambezeleka okuphansi, kusize ukuthuthukisa ukusebenza nolwazi lomsebenzisi lwamadivayisi omsindo we-Bluetooth.
Ngamafuphi, i-LE Audio izoletha izinketho eziningi zobuchwepheshe bekhodekhi kumadivayisi alalelwayo e-Bluetooth, ukuze kuhlangatshezwane nezidingo zabasebenzisi abahlukene ngekhwalithi yomsindo nokusetshenziswa kwamandla.
I-LE Audio Bluetooth Module
I-Feasycom iphinde ithuthukise amamojula e-Bluetooth asekelwe kubuchwepheshe bomkhiqizo we-LE Audio. Ngokukhishwa kwemikhiqizo emisha efana ne-BT631D ne-BT1038X, inganikeza ikhwalithi yomsindo engcono kanye nokusetshenziswa kwamandla okuphansi, futhi ibe nemisebenzi eminingi nezici. Ukukhetha okuhle kakhulu kokwenza amadivayisi alalelwayo e-Bluetooth.
