Kodi LE Audio ndi chiyani?
LE Audio ndi mulingo watsopano waukadaulo wamawu womwe unayambitsidwa ndi Bluetooth Special Interest Group (SIG) mu 2020. Zimatengera mphamvu ya Bluetooth low-energy 5.2 ndipo imagwiritsa ntchito zomangamanga za ISOC (isochronous). LE Audio imabweretsa luso lamakono la LC3 audio codec algorithm, lomwe limapereka latency yotsika komanso mawonekedwe apamwamba otumizira. Imathandiziranso zinthu monga kulumikizana ndi zida zambiri komanso kugawana mawu, kupatsa ogula chidziwitso chapamwamba kwambiri.
Ubwino wa LE Audio poyerekeza ndi Classic Bluetooth
LC3 kodi
LC3, monga codec yovomerezeka yothandizidwa ndi LE Audio, ndiyofanana ndi SBC mumtundu wapamwamba wa Bluetooth. Yatsala pang'ono kukhala codec yodziwika bwino yamtsogolo ya Bluetooth audio. Poyerekeza ndi SBC, LC3 imapereka:
- Higher Compression Ratio (Lower Latency):
LC3 imapereka chiŵerengero chapamwamba cha kuponderezana poyerekeza ndi SBC mumtundu wapamwamba wa Bluetooth, zomwe zimapangitsa kuti mukhale otsika kwambiri. Pa data ya stereo pa 48K/16bit, LC3 imakwaniritsa chiŵerengero chapamwamba cha 8:1 (96kbps), pamene SBC imagwira ntchito pa 328kbps pa data yomweyo.
- Ubwino Womveka Womveka:
Pa bitrate yomweyo, LC3 imaposa SBC mumtundu wamawu, makamaka pogwira ma frequency apakati mpaka otsika.
- Kuthandizira Kwamitundu Yosiyanasiyana Yomvera:
LC3 imathandizira maulendo azithunzi a 10ms ndi 7.5ms, 16-bit, 24-bit, ndi 32-bit audio sampling, chiwerengero chopanda malire cha mayendedwe omvera, ndi maulendo a zitsanzo za 8kHz, 16kHz, 24kHz, 32kHz, 44.1kHz ndi 48kHz.
Multi-Stream Audio
- Thandizo kwa Angapo Odziyimira Pawokha, Amayimidwe Amawu Olumikizana:
Zomvera zotsatizana zingapo zimathandizira kufalitsa ma audio angapo odziyimira pawokha, olumikizidwa pakati pa chipangizo chomvera (monga foni yam'manja) ndi chipangizo chimodzi kapena zingapo zolandirira mawu. Njira Yopitilira Isochronous Stream (CIS) imakhazikitsa maulumikizidwe amphamvu a Bluetooth ACL pakati pa zida, kuwonetsetsa kuti kulumikizana kwa True Wireless Stereo (TWS) ndi kutsika kotsika, kulumikizidwa kwamawu ambiri.
Broadcast Audio Mbali
- Kuwulutsa Zomvera ku Zida Zopanda Malire:
Mawonekedwe a Broadcast Isochronous Stream (BIS) mu LE Audio amalola chida chothandizira kuwulutsa mawu amodzi kapena angapo pazida zopanda malire za zida zomvera. BIS idapangidwa kuti izikhala ndi makanema apagulu, monga kumvetsera kwa TV mwakachetechete m'malo odyera kapena zolengeza zapagulu m'ma eyapoti. Imathandizira kuseweredwa kwamawu kolumikizidwa pa chipangizo chilichonse cholandirira ndikupangitsa kusankha mitsinje yeniyeni, monga kusankha nyimbo ya chilankhulo powonetsera kanema. BIS ndi yapadziko lonse lapansi, imasunga kusinthana kwa data, imachepetsa kugwiritsa ntchito mphamvu, ndipo imatsegula mwayi watsopano womwe sunapezeke m'mbuyomu pogwiritsa ntchito zida zapamwamba za Bluetooth.
Zochepa za LE Audio
LE Audio ili ndi maubwino monga ma audio apamwamba kwambiri, kugwiritsa ntchito mphamvu pang'ono, kutsika pang'ono, kuyanjana kwamphamvu, komanso kuthandizira kwamalumikizidwe angapo. Komabe, monga teknoloji yatsopano, ilinso ndi malire ake:
- Zogwirizana ndi Chipangizo:
Chifukwa cha kuchuluka kwamakampani pamsika, kuyimitsidwa ndi kukhazikitsidwa kwa LE Audio kumakumana ndi zovuta, zomwe zimapangitsa kuti pakhale zovuta zofananira pakati pazinthu zosiyanasiyana za LE Audio.
- Performance Bottlenecks:
Kuvuta kwapamwamba kwa LC3 ndi LC3 kuphatikiza ma codec ma aligorivimu kumayika zofuna zina pa mphamvu yopangira chip. Tchipisi zina zitha kuthandizira protocol koma zimavutikira kuti zigwire bwino ntchito yosunga ma encoding ndi decoding.
- Zida Zochepa Zothandizira:
Pakadali pano, pali zida zochepa zomwe zimathandizira LE Audio. Ngakhale zotsatsa zam'manja kuchokera pazida zam'manja ndi opanga mahedifoni ayamba kubweretsa LE Audio, m'malo mwake mudzafunikabe nthawi. Kuti athane ndi ululu uwu, Feasycom wayambitsa mwatsopano gawo loyamba la Bluetooth padziko lonse lapansi lomwe limathandizira LE Audio ndi Classic Audio panthawi imodzi, kulola kukulitsa kwatsopano kwa LE Audio magwiridwe antchito popanda kusokoneza zomwe ogwiritsa ntchito a Classic Audio.
Mapulogalamu a LE Audio
Kutengera maubwino osiyanasiyana a LE Audio, makamaka Auracast (kutengera mawonekedwe a BIS), itha kugwiritsidwa ntchito pazomvera zingapo kuti muwonjezere zomvera za ogwiritsa ntchito:
- Kugawana Kwawekha Kwamawu:
Broadcast Isochronous Stream (BIS) imalola kuti nyimbo imodzi kapena zingapo zigawidwe ndi zida zopanda malire, zomwe zimathandiza ogwiritsa ntchito kugawana zomvera zawo ndi mahedifoni apafupi a ogwiritsa ntchito pogwiritsa ntchito mafoni awo kapena mapiritsi.
- Kumvetsera Kowonjezera/Kothandiza Pamalo a Anthu:
Auracast sikuti imangothandiza kupereka kufalikira kwa anthu osamva komanso kupititsa patsogolo kupezeka kwa mautumiki othandizira omvera komanso imakulitsa magwiridwe antchito a makinawa kwa ogula omwe ali ndi milingo yosiyanasiyana yamakutu.
- Thandizo la Zinenero Zambiri:
M'malo omwe anthu azilankhulo zosiyanasiyana amasonkhana, monga malo ochitira misonkhano kapena malo owonera kanema, Auracast imatha kumasulira nthawi imodzi m'chilankhulo chawo.
- Mayendedwe Otsogolera:
M'malo monga malo osungiramo zinthu zakale, masitediyamu amasewera, ndi malo okopa alendo, ogwiritsa ntchito amatha kugwiritsa ntchito zomvera m'makutu kapena zomvera m'makutu kuti amvetsere mayendedwe omvera, zomwe zimapatsa chidwi kwambiri.
- Silent TV Screens:
Auracast imalola ogwiritsa ntchito kumvetsera zomvera kuchokera pa TV pamene palibe phokoso kapena phokoso liri lochepa kwambiri kuti asamve, kupititsa patsogolo chidziwitso kwa alendo m'malo monga malo ochitira masewera olimbitsa thupi ndi masewera.
Tsogolo la LE Audio
Malinga ndi zolosera za ABI Research, pofika 2028, kuchuluka kwapachaka kwa zida zothandizidwa ndi LE Audio kudzafika 3 miliyoni, ndipo pofika 2027, 90% ya mafoni a m'manja omwe amatumizidwa pachaka azithandizira LE Audio. Mosakayikira, LE Audio idzayendetsa kusintha kwa gawo lonse la audio la Bluetooth, kupitilira kufalikira kwamawu achikhalidwe kupita kuzinthu zomwe zili pa intaneti ya Zinthu (IoT), nyumba zanzeru, ndi madera ena.
