Chii chinonzi Bluetooth Audio Codec
Bluetooth odhiyo codec inoreva tekinoroji yekodhi yekodhi inoshandiswa mukufambiswa kweBluetooth audio.
Yakajairika Bluetooth audio codecs
Yakajairika Bluetooth audio codecs pamusika inosanganisira SBC, AAC, aptX, LDAC, LC3, nezvimwe.
SBC ndeye basic audio codec inoshandiswa zvakanyanya muBluetooth mahedhifoni, vatauri uye zvimwe zvishandiso. AAC ndeyepamusoro-inoshanda audio codec inonyanya kushandiswa paApple zvishandiso. aptX tekinoroji yecodec yakagadziridzwa neQualcomm inopa zvirinani odhiyo mhando uye yakaderera latency yemhando yepamusoro-yekupedzisira madhidhiyo eBluetooth. LDAC tekinoroji yekodeki yakagadziridzwa naSony, inogona kutsigira yakakwira-resolution audio transmission kusvika ku96kHz/24bit, uye inokodzera midziyo yepamusoro yekuteerera.
Musika weBluetooth audio codec unoramba uchikura sezvo kudiwa kwevatengi kweyemhando yepamusoro kunoramba kuchiwedzera. Mune ramangwana, nekuzivikanwa kwe5G tekinoroji uye kuenderera mberi kukwidziridzwa kweBluetooth tekinoroji, iyo Bluetooth audio codec musika ichava neyakakura tarisiro yekushandisa.
LC3 Bluetooth audio codecs
Pakati pavo, LC3 inyanzvi yekodeki yakagadzirwa neSIG[F1] , iyo inogona kupa yakakwira odhiyo mhando uye yakaderera simba rekushandisa. Kuenzaniswa neyechinyakare SBC codec, LC3 inogona kupa yakakwira bit rates, zvichikonzera zvirinani odhiyo mhando. Panguva imwecheteyo, inogona zvakare kuwana yakaderera mashandisiro emagetsi pachiyero chimwe chete, zvichibatsira kuwedzera hupenyu hwebhatiri hwechishandiso.
LC3 tekinoroji maficha, anosanganisira:
- 1. Block-based shandura audio codec
- 2. Ipa akawanda kumhanya
- 3. Kutsigira furemu nguva dzegumi ms uye 10 ms
- 4. Iyo quantization bit upamhi hweyega yega sampu yekuteerera ndeye 16, 24 uye 32 bits, kureva, iyo PCM data bit upamhi.
- 5. Kutsigira sampling rate: 8 kHz, 16 kHz, 24 kHz, 32 kHz, 44.1 kHz uye 48 kHz
- 6. Tsigira nhamba isingagumi yematanho ekuteerera
LC3 uye LE Audio
LC3 tekinoroji chinhu chinotsigira cheLE Audio zvigadzirwa. Iyo idhidhiyo yekufambisa chiyero muBluetooth yakaderera simba tekinoroji. Ichatsigira akawanda maodhiyo macodecs kuti ape zvirinani odhiyo mhando uye yakaderera mashandisiro emagetsi.
Mukuwedzera, LE Audio inotsigirawo mamwe macodec technologies, anosanganisira AAC, aptX Adaptive, etc. Aya macodec tekinoroji anogona kupa zvirinani audio quality uye yakaderera latency, zvichibatsira kuvandudza mashandiro uye ruzivo rwemushandisi weBluetooth audio zvishandiso.
Muchidimbu, LE Audio ichaunza mamwe macodec tekinoroji sarudzo dzeBluetooth odhiyo zvishandiso, kuitira kuti isangane nezvinodiwa zvevashandisi vakasiyana zvemhando yekuteerera uye mashandisiro emagetsi.
LE Audio Bluetooth Module
Feasycom inogadzirawo maBluetooth modules yakavakirwa LE Audio chigadzirwa tekinoroji. Nekuburitswa kwezvigadzirwa zvitsva zvakaita seBT631D uye BT1038X, vanogona kupa zvirinani mhando yekuteerera uye kuderera kwesimba rekushandisa, uye zvakare kuve neakawanda mabasa uye maficha. Yakanakisa sarudzo yekugadzira Bluetooth odhiyo zvishandiso.
