Njengoko usazi, umgangatho wesandi, ukubambezeleka kwezixhobo ezahlukeneyo zeBluetooth kunokwahluka ngokubanzi. Siyintoni isizathu? Namhlanje siza kukunika impendulo kulo mbuzo.
Ukuhanjiswa kwe-audio ekumgangatho ophezulu weBluetooth isekelwe ikakhulu kwiprofayile ye-A2DP. I-A2DP ichaza ngokulula iprothokholi kunye nenkqubo yokuhambisa ulwazi olukwikhwalithi ephezulu ye-audio efana ne-mono okanye i-stereo kwisitishi esingenanxibelelwano esingahambelaniyo. Le protocol iyafana nombhobho wothumelo lwedatha yeaudiyo. Idatha egqithiswe ngeBluetooth yahlulwe ngokwezi ntlobo zilandelayo ngokwefomathi yekhowudi:
yintoni SBC
Le yifomati esemgangathweni yekhowudi yomsindo weBluetooth. I-A2DP (iProfayili yoSabelo lweAudio ePhezulu) ifomathi enyanzelekileyo yekhowudi yeprotocol. Umlinganiselo ophezulu ovumelekileyo yi-320kbit / s kwi-mono kunye ne-512kbit / s kwiitshaneli ezimbini. Zonke iichips zeBluetooth ezimanyelwayo ziya kuxhasa le fomati yokufaka ikhowudi yomsindo.
yintoni AAC
Itekhnoloji ebonelelwa yiDolby Laboratories, luxinzelelo oluphezulu lwe-encoding algorithm. I-iPhone isebenzise ifomathi ye-AAC yosasazo lweBluetooth. Okwangoku, izixhobo zomsindo zeBluetooth zeApple zisebenzisa itekhnoloji yokukhowuda ye-AAC. Kwaye uninzi lwezixhobo ezifumana izixhobo ezinjengezithethi zeBluetooth / ii-headsets kwimarike zikwaxhasa ukuchazwa kwe-AAC.
yintoni APTX
Yialgorithm ye-CSR yelungelo elilodwa lomenzi wechiza. Emva kokuba ifunyenwe yiQualcomm, yaba yitekhnoloji yekhowudi yayo ephambili. Kubhengezwa kuluntu ukuba inokufikelela umgangatho wesandi seCD. Uninzi lweefowuni ezintsha ze-Android zixhotyiswe nge-APTX. Le teknoloji yekhowudi yomsindo isebenze ngakumbi kunekhowudi yeBluetooth yeklasikhi, kwaye ukuva okumamelayo kungcono kunezimbini ezidlulileyo. Izixhobo ezisebenzisa iteknoloji ye-APTX kufuneka zifake isicelo sogunyaziso kwi-Qualcomm kwaye zihlawule iindleko zogunyaziso, kwaye kufuneka zixhaswe zizo zombini iziphelo zokuthumela kunye nokufumana.
yintoni APTX-HD
I-aptX HD yi-audio-definition ephezulu, kwaye umgangatho wesandi uphantse ufana ne-LDAC. Isekwe kwi-aptX yakudala, eyongeza amajelo okuxhasa i-24 bit 48KHz ifomathi yomsindo. Iingenelo zoku kumlinganiselo ophantsi wesignali ukuya kwingxolo kunye nokuphazamiseka okuncinci. Kwangaxeshanye, izinga losulelo ngokuqinisekileyo lonyuswe kakhulu.
yintoni I-APTX-LL
I-aptX LL iphantsi-latency, eyona nto iphambili kukuba inokufikelela kwi-latency engaphantsi kwe-40ms. Siyazi ukuba umda we-latency onokuthi abantu bazive yi-70ms, kwaye ukufikelela kwi-40ms kuthetha ukuba asinakuva ukulibaziseka.
yintoni I-LDAC
Le yitekhnoloji yekhowudi yomsindo ephuhliswe yi-SONY, enokuhambisa umxholo womsindo we-high-resolution (Hi-Res). Ubuchwephesha bunokusasaza malunga nokuphindwe kathathu kunobunye ubuchwephesha beekhowudi ngosetyenziso olusebenzayo kunye nokupakishwa okuncinci kwedatha. Okwangoku, obu buchwephesha busetyenziswa kuphela kwisixhobo sika-SONY sokuhambisa nokwamkela. Ngoko ke, kuphela iseti ye-SONY yokudlulisa kunye nokufumana izixhobo ezixhasa iteknoloji yekhowudi yomsindo ye-LDAC inokuthengwa ukuxhasa ukuhanjiswa kwedatha ye-Bluetooth ye-LDAC-encoded.
I-Feasycom ibonise izisombululo ezimbalwa zemodyuli ezixhasa iifomathi ze-APTX. Onokuzifumana ngezantsi:
