Bluetooth Audio Codec yog dab tsi
Bluetooth audio codec hais txog lub suab codec tshuab siv hauv Bluetooth audio transmission.
Common Bluetooth audio codecs
Feem ntau Bluetooth audio codecs ntawm lub khw muaj xws li SBC, AAC, aptX, LDAC, LC3, thiab lwm yam.
SBC yog ib qho yooj yim suab codec siv dav hauv Bluetooth headsets, hais lus thiab lwm yam khoom siv. AAC yog qhov ua tau zoo ntawm lub suab codec feem ntau siv ntawm Apple li. aptX yog lub tshuab codec tsim los ntawm Qualcomm uas muab lub suab zoo dua thiab qis dua latency rau high-end Bluetooth audio devices. LDAC yog lub tshuab codec tsim los ntawm Sony, uas tuaj yeem txhawb nqa lub suab xa tawm siab txog 96kHz / 24bit, thiab tsim nyog rau cov khoom siv suab siab.
Bluetooth audio codec lag luam tseem loj hlob ntxiv raws li cov neeg siv khoom xav tau rau lub suab zoo tseem nce ntxiv. Nyob rau hauv lub neej yav tom ntej, nrog rau qhov nrov ntawm 5G thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm Bluetooth thev naus laus zis, Bluetooth audio codec lag luam yuav muaj kev cia siab rau daim ntawv thov dav dua.
LC3 Bluetooth audio codecs
Ntawm lawv, LC3 yog codec technology tsim los ntawm SIG[F1] , uas tuaj yeem muab lub suab zoo dua thiab siv hluav taws xob qis dua. Piv nrog rau SBC codec ib txwm muaj, LC3 tuaj yeem muab cov nqi qis dua, ua rau lub suab zoo dua. Nyob rau tib lub sijhawm, nws tseem tuaj yeem ua tiav kev siv hluav taws xob qis ntawm tib tus nqi me ntsis, pab txuas lub roj teeb lub neej ntawm lub cuab yeej.
LC3 technical nta, suav nrog:
- 1. Thaiv-raws li hloov suab codec
- 2. Muab ntau yam ceev
- 3. Txhawb cov ntu ntu ntawm 10 ms thiab 7.5 ms
- 4. Lub quantization ntsis dav ntawm txhua lub suab qauv yog 16, 24 thiab 32 khoom, uas yog, PCM cov ntaub ntawv me ntsis dav
- 5. Kev them nyiaj yug tus nqi: 8 kHz, 16 kHz, 24 kHz, 32 kHz, 44.1 kHz thiab 48 kHz
- 6. Txhawb nqa cov xov tooj tsis txwv
LC3 and LE Audio
LC3 thev naus laus zis yog qhov txhawb nqa ntawm LE Audio cov khoom lag luam. Nws yog tus qauv kis tau tus mob hauv Bluetooth qis zog thev naus laus zis. Nws yuav txhawb nqa ntau lub suab codecs los muab lub suab zoo dua thiab siv zog qis dua.
Tsis tas li ntawd, LE Audio kuj txhawb nqa lwm cov tshuab codec, suav nrog AAC, aptX Adaptive, thiab lwm yam. Cov tshuab codec no tuaj yeem muab cov suab zoo dua thiab qis dua, pab txhim kho kev ua haujlwm thiab cov neeg siv kev paub ntawm Bluetooth audio devices.
Nyob rau hauv luv luv, LE Audio yuav coj ntau codec technology xaiv rau Bluetooth suab pab kiag li lawm, thiaj li ua tau raws li cov kev xav tau ntawm cov neeg siv sib txawv rau lub suab zoo thiab lub zog noj.
LE Audio Bluetooth Module
Feasycom kuj tseem txhim kho Bluetooth modules raws li LE Audio cov khoom siv thev naus laus zis. Nrog rau kev tso tawm ntawm cov khoom tshiab xws li BT631D thiab BT1038X, lawv tuaj yeem muab cov suab zoo dua thiab siv zog qis dua, thiab tseem muaj ntau yam haujlwm thiab nta. Kev xaiv zoo heev rau kev tsim cov khoom siv suab Bluetooth.
