Ii-codecs ezi-3 eziphambili abaziqhelileyo abaphulaphuli abaninzi yi-SBC, i-AAC kunye ne-aptX:
I-SBC - i-Subband Coding - Ikhowudi ye-codec enyanzelekileyo kunye nemiselweyo yazo zonke ii-headphone ze-stereo zeBluetooth ezineProfayili yokusasazwa komsindo oPhezulu (A2DP). Iyakwazi ukwenza iireyithi zebit ukuya kuthi ga kwi-328 kbps ngereyithi yesampulu ye-44.1Khz. Ibonelela ngomgangatho olungileyo weaudio ngaphandle kokufuna amandla amaninzi okucubungula ukubethela okanye ukucacisa. Nangona kunjalo, umgangatho womsindo unokungahambelani ngamanye amaxesha. Oku kuphawuleka ngakumbi nge-Bluetooth transmitter enexabiso eliphantsi.
I-AAC-Ukufakwa kweKhowudi yeAudiyo ekwinqanaba eliphezulu- Iyafana ne-SBC kodwa ngesandi esingcono. Le codec ithandwa kakhulu kwiqonga iTunes iTunes kunye nezinye izicelo non-wireless. Nangona kunjalo, ayiqhelekanga kakhulu, ngakumbi kwii-headphones.
aptX - Ikhodekhi yomnini kunye neyokuzikhethela eyilwe yiCSR. Ilungele ukubanga izicelo zeaudio kuba ifaka i-audio ngokufanelekileyo kwaye ngesantya esingaphezulu kancinci kune-SBC. Kukwakho neenguqu ezimbini ezongezelelweyo i-aptX(LL) kunye ne-aptX HD enokuthi inciphise kakhulu ukubambezeleka koqhagamshelo okanye iphucule kakhulu umgangatho wayo womsindo. Nangona kunjalo, ngumda omncinci njengoko zombini isidluliseli seBluetooth kunye nomamkeli kufuneka abe ne-aptX okanye iinguqulelo zayo ukuze icodec isebenze.
Ukuhamba
Ii-codecs zinempembelelo enkulu kwi-latency (funda ngakumbi ngolu vavanyo) kunomgangatho wesandi kubaphulaphuli abaninzi. Uqhagamshelo lwe-SBC olungagqibekanga ludla ngokuba ne-100 ms ye-latency ebonakalayo xa ubukele iividiyo kwaye inokuba qatha ngokwaneleyo ukuyonakalisa amava akho emidlalo.
Ukulungisa eminye imiba yongqamaniso ebangelwa kukubambezeleka, iCSR iphuhlise i-aptX kwaye emva koko i-aptX-Low Latency codec. I-aptX eqhelekileyo iyayiphucula i-latency ngenxa ye-algorithm yayo ye-encoding esebenzayo kune-SBC. Nangona kunjalo, i-aptX-LL ineyona mpembelelo ibonakalayo kwi-latency.
isiphelo
I-Codecs zii-algorithms ezicinezela idatha ukuze kube lula kunye nokuhanjiswa ngokukhawuleza. Ubhalo olungcono kunye ne-decoding algorithms kuthetha ilahleko encinci yosasazo olunokunceda kumgangatho weaudio. Siqaphele ukuba ii-codecs zinempembelelo enkulu kwi-latency kunomgangatho wesandi.
