Chii chinonzi LE Audio?
LE Audio ndiyo itsva yekuteerera tekinoroji mwero yakaunzwa neBluetooth Special Interest Group (SIG) muna 2020. Yakavakirwa paBluetooth low-energy 5.2 uye inoshandisa ISOC (isochronous) architecture. LE Audio inosvitsa iyo itsva LC3 odhiyo codec algorithm, iyo inopa yakaderera latency uye yakakwirira kutapurirana mhando. Iyo zvakare inotsigira maficha akadai seakawanda-chishandiso chekubatanidza uye kugovera odhiyo, ichipa vatengi ruzivo rwepamusoro rweodhiyo.
Zvakanakira LE Audio zvichienzaniswa neClass Bluetooth
LC3 Codec
LC3, seyoyo inosungirwa codec inotsigirwa neLE Audio, yakaenzana neSBC mune yekare Bluetooth audio. Yakagadzirira kuve iyo huru codec yeramangwana Bluetooth odhiyo. Kuenzaniswa neSBC, LC3 inopa:
- Higher Compression Ratio (Lower Latency):
LC3 inopa yakakwira compression reshiyo ichienzaniswa neSBC mune yekare Bluetooth odhiyo, zvichikonzera yakaderera latency. Kune stereo data pa48K/16bit, LC3 inowana yakakwirira-kutendeseka compression reshiyo ye8: 1 (96kbps), nepo SBC ichiwanzo shanda pa328kbps kune imwecheteyo data.
- Better Sound Quality:
Panguva imwecheteyo bitrate, LC3 inodarika SBC mumhando yeaudio, kunyanya mukubata pakati-kusvika-pasi ma frequency.
- Tsigiro yeMaodhiyo Akasiyana Mafomati:
LC3 inotsigira furemu dzegumi neshanu uye 10ms, 7.5-bit, 16-bit, uye 24-bit odhiyo sampling, nhamba isina muganho yematanho ekuteerera, uye sampling frequencies ye32kHz, 8kHz, 16kHz, 24kHz, 32kHz uye 44.1kHz.
Multi-Stream Audio
- Tsigiro yeMazhinji Akazvimiririra, Akawiriraniswa Odhiyo nzizi:
Multi-stream odhiyo inogonesa kutapurirana kweakawanda akazvimirira, akawiriraniswa odhiyo hova pakati peodhiyo sosi mudziyo (semuenzaniso, smartphone) uye imwe kana anopfuura ekugamuchira odhiyo mudziyo. Iyo Inoenderera Isochronous Stream (CIS) modhi inomisikidza yakaderera-simba Bluetooth ACL kubatana pakati pezvishandiso, kuve nechokwadi chiri nani Yechokwadi Wireless Stereo (TWS) kuwiriranisa uye yakaderera-latency, yakawiriraniswa akawanda-rukova odhiyo kutapurirana.
Broadcast Audio Feature
- Kutepfenyura Audio kune Unlimited Devices:
Iyo Broadcast Isochronous Stream (BIS) modhi muLE Audio inobvumira odhiyo sosi mudziyo kutepfenyura imwe kana akawanda maodhiyo nzizi kune isina muganho wehuwandu hwekugamuchira odhiyo michina. BIS yakagadzirirwa zviitiko zvekutepfenyura zveveruzhinji, sekuteerera TV chinyararire mumaresitorendi kana zviziviso zveveruzhinji munhandare dzendege. Iyo inotsigira yakawiriraniswa yekutamba yekuteerera pane yega yega inogashira mudziyo uye inogonesa kusarudzwa kweakananga hova, sekusarudza rwiyo rwemutauro mune yebhaisikopo theatre marongero. BIS haina unidirectional, inochengetedza shanduko yedata, inoderedza mashandisiro emagetsi, uye inovhura mikana mitsva yaimbove isingawanikwe neyekare Bluetooth kuita.
Kuganhurirwa kweLE Audio
LE Audio ine mabhenefiti akadai seyepamusoro odhiyo mhando, yakaderera simba mashandisiro, yakaderera latency, kwakasimba kupindirana, uye kutsigirwa kweakawanda-akabatana. Nekudaro, setekinoroji nyowani, inewo painogumira:
- Device Compatibility Issues:
Nekuda kwekuwanda kwemakambani muindastiri, kumisikidzwa uye kutorwa kweLE Audio kutarisana nematambudziko, zvichitungamira kunyaya dzekuenderana pakati pezvakasiyana LE Audio zvigadzirwa.
- Performance Bottlenecks:
Iyo yakanyanya kuomarara yeLC3 uye LC3 pamwe necodec algorithms inoisa zvimwe zvinodikanwa pane chip kugadzirisa simba. Mamwe machipi anogona kutsigira protocol asi anonetseka kubata encoding uye decoding maitiro nemazvo.
- Zvishoma Zvinotsigirwa Zvishandiso:
Parizvino, kune mashoma mashoma anotsigira LE Audio. Kunyangwe zvigadzirwa zvemureza kubva kunharembozha uye vanogadzira mahedhifoni vatanga kuunza LE Audio, kutsiva kwakazara kuchiri kuda nguva. Kugadzirisa dambudziko iri, Feasycom yakaunza hunyanzvi yekutanga Bluetooth module yepasi inotsigira LE Audio uye Classic Audio panguva imwe chete, inobvumira kuvandudzwa kwe LE Audio mashandiro pasina kukanganisa ruzivo rwemushandisi rweClass Audio.
Zvishandiso zveLE Audio
Zvichienderana neakasiyana mabhenefiti eLE Audio, kunyanya iyo Auracast (zvichienderana neBIS modhi), inogona kushandiswa mune akawanda maodhiyo mamiriro ekusimudzira ruzivo rwevashandisi.
- Pachako Kugovera Audio:
Iyo Broadcast Isochronous Stream (BIS) inobvumira imwe kana anopfuura maodhiyo nzizi kugovaniswa nenhamba isina muganho yemidziyo, zvichiita kuti vashandisi vagovane yavo yekuteerera nemahedhifoni evashandisi vari pedyo vachishandisa mafoni avo kana mahwendefa.
- Kuteerera kwakawedzerwa/Kunobatsira munzvimbo dzeruzhinji:
Auracast haingobatsire kupa kutumirwa kwakafara kune vasinganzwe uye kuvandudza kuwanikwa kweanobatsira ekuteerera masevhisi asiwo inowedzera kushanda kweaya masisitimu kune vatengi vane mazinga akasiyana ehutano hwekunzwa.
- Tsigiro yemitauro yakawanda:
Munzvimbo dzinoungana vanhu vemitauro yakasiyana, senge nzvimbo dzemisangano kana mabhaisikopo, Auracast inogona kupa shanduro panguva imwe chete mumutauro wemushandisi.
- Tour Guide Systems:
Munzvimbo dzakaita semamiziyamu, nhandare dzemitambo, uye zvinokwezva vashanyi, vashandisi vanogona kushandisa mahedhifoni kana mahedhifoni avo kuteerera kushanya kutenderera, zvichipa ruzivo rwakanyanya.
- Silent TV Screens:
Auracast inobvumira vashandisi kuteerera kune odhiyo kubva paTV kana pasina ruzha kana iyo vhoriyamu yakadzikira kuti unzwe, ichiwedzera ruzivo kune vashanyi munzvimbo dzakaita sejimu nemabhawa emitambo.
Ramangwana Trends ye LE Audio
Zvinoenderana nekufungidzira kweABI Research, panosvika 2028, huwandu hwegore hwekutumira hweLE Audio-inotsigirwa zvishandiso huchasvika mamirioni matatu, uye panosvika 3, makumi mapfumbamwe muzana emafoni emafoni anotumirwa pagore achatsigira LE Audio. Pasina kupokana, LE Audio ichafambisa shanduko mune yese Bluetooth odhiyo ndima, ichiwedzera kupfuura echinyakare odhiyo kutapurirana kune maapplication muInternet yezvinhu (IoT), dzimba dzakangwara, nedzimwe nzvimbo.
Feasycom's LE Audio Zvigadzirwa
Feasycom yakatsaurirwa kutsvagurudzo nekuvandudza maBluetooth module, kunyanya mumunda weBluetooth odhiyo, inotungamira iyo indasitiri ine hunyanzvi hwepamusoro-performance modules uye vanogamuchira. Kuti udzidze zvakawanda, shanya
