Ma codec akuluakulu atatu omwe omvera ambiri amawadziwa ndi SBC, AAC ndi aptX:
SBC - Subband Coding - Codec yovomerezeka komanso yokhazikika pamakutu onse a stereo Bluetooth okhala ndi Advanced Audio Distribution Profile (A2DP). Imatha kutsitsa mitengo mpaka 328 kbps yokhala ndi zitsanzo za 44.1Khz. Amapereka mtundu wabwino wamawu osafunikira mphamvu zambiri zosinthira kuti alembe kapena kutsitsa. Komabe, mtundu wa audio ukhoza kukhala wosagwirizana nthawi zina. Izi zimawonekera makamaka ndi chotengera chotsika mtengo cha Bluetooth.
AAC - Advanced Audio Coding - Zofanana ndi SBC koma zomveka bwino. Codec iyi imakonda kwambiri nsanja ya Apple ya iTunes ndi mapulogalamu ena omwe si opanda zingwe. Komabe, sizodziwika kwambiri, makamaka kwa mahedifoni.
aptX - Kodeki yaumwini komanso yosankha yopangidwa ndi CSR. Ndiwoyenera kuyitanitsa mapulogalamu amawu chifukwa imasunga zomvera bwino komanso pamlingo wokwera pang'ono kuposa SBC. Palinso mitundu iwiri yowonjezera ya aptX(LL) ndi aptX HD yomwe imachepetsa kwambiri kuchedwa kwa kulumikizidwa kapena kumapangitsa kuti mawu ake azimveka bwino. Komabe, ndizochepa pang'ono chifukwa chotumizira Bluetooth ndi wolandila ayenera kukhala ndi aptX kapena kusiyanasiyana kwake kuti codec igwire ntchito.
Latency
Ma codec amakhudza kwambiri latency (phunzirani zambiri za mayesowa) kusiyana ndi mtundu wamawu kwa omvera ambiri. Kulumikizana kosasinthika kwa SBC nthawi zambiri kumakhala ndi latency yopitilira 100 ms yomwe imawonekera mukawonera makanema ndipo ikhoza kukhala yowopsa kwambiri kuwononga zomwe mumachita pamasewera.
Kukonza zina mwazovuta zoyanjanitsidwa ndi latency, CSR idapanga aptX kenako codec ya aptX-Low Latency. AptX yanthawi zonse imasintha pang'onopang'ono chifukwa cha ma encoding algorithm yake yopambana kuposa SBC. Komabe, aptX-LL imakhudza kwambiri latency.
Kutsiliza
Ma codecs ndi ma aligorivimu omwe amapondereza deta kuti ifalitse mosavuta komanso mwachangu. Ma encoding abwinoko ndi ma aligorivimu amatanthawuza kufalitsa kotayika komwe kungathandize ndi mtundu wamawu. Tawona kuti ma codec amakhudza kwambiri latency kuposa mtundu wamawu.
