Yintoni bitrate? Nangendlela oku kunempembelelo ngayo umgangatho umculo neevidiyo?

Bitrate iboniswe njengenye iimpawu eziphambili yevidiyo kunye ezirekhodiweyo. Abantu abaninzi zisetyenziswa ukuba bacinge ukuba kugqiba umgangatho ifayile ezilayishwe. Kodwa yintoni na bitrate nendlela okunene bachaza umculo kunye umboniso? Makhe sihlolisise le zolwimi ngokunzulu.

Yintoni bitrate?

Bitrate - ixabiso esibonakalisa inani inkcazelo (kilobits okanye megabits), yi iyalungisa kwindawo sokudlala ifayili yesibini. Ngako oko, oko ulinganiswa megabits yesibini nganye (mbps) okanye kilobits yesibini (kbps) nganye. Kungenjalo, izinga bit kungachazwa njengokuba ububanzi bandwidth. Olu phawu kubalulekile kwabo bafuna ukuguqula le fayile, ngokuba ubude efanayo bitrate kokukhona luya kwandisa ifayile. Ukongeza ngokobungakanani, ngokunjalo izinga lesandi. Ukunciphisa ubungakanani ngokuthotywa isantya sebhithi kuthiwa ucinezelo.

Common umculo format MP3 yi ifayile emanyelwayo zixinaniswe kangangokuba ukuba standard a disc ongama ukuya kwiiyure ezili-12 umculo. Umgangatho ihlala eliphezulu ngenxa ucinezelo psychoacoustic: uluhlu olupheleleyo izandi zicocwa kunye ezitsho kunye namanqanaba umthamo singafakwanga yi kwindlebe yomntu. izandi ezikhethiweyo akhiwa kwiiyunithi ezahlukeneyo ezibizwa izakhelo. Izakhelo ezo ngexesha elifanayo kwaye omsindo zixinaniswe nge algorithm elinikiweyo. Xa udlala umculo, lo signal ngokutsha ukusuka iibhloko decoded ngokokulandelelana.

Yintoni ngokuqhelekileyo kusetyenziswa ucinezelo?

bitrate Audio edla 256 kbit / s. Nalo eli xabiso le ushicilelo emanyelwayo zixinaniswe ngesantya nama-6 amaxesha, ngoko kwesinye disc Unokurekhoda ukuya ku amaxesha 6 ngaphezulu umculo kunangaphambili ucinezelo. Ukuba isantya sebhithi elisezantsi ukuya ku 128 kbit / s, oko kuya ilingane kwelinye disc 12 amaxesha umculo, kodwa umgangatho isandi liya kuba ngaphantsi kakhulu. Umculo embhalweni 128 kbit / s, ukumenywa ukumamela Internet, oko kukuthi. To. Bafuna ukunyusa isantya kulayishwa amaphepha abanini bezinto eziyimfuno ukwenza nawuphi na umbingelelo. abasebenzisi abaninzi bathi umgangatho wayo zimbi.

Ngoku, xa kwacaca ukuba ezinjalo iirhafu bit, lixesha ukuqinisekisa izinga eliphezulu. Zombini amateurs kunye neengcali bathi ngonaphakade njengoko bitrate kuchaphazela umgangatho audio nokuba kuchaphazela. albhamu zomculo, ngokuqhelekileyo kubonisiwe isantya sebhithi. Enye efanayo disc zibhalwe 128 kbit / s kunye 256 Kbit / s, ziya kwahluka phakathi kwexabiso kabini.

Eyiyo isantya sebhithi ukuba iimeko ukuphulaphula ezahlukeneyo

Kuba abantu abaninzi, a ucinezelo elinambini angezanga nawuphi na umonakalo, lo gama abanye bathi ukuba abakwazi ukuphulaphula umculo bitrates ephantsi kwe-320 Kbit / s. Ngumzali, unelungelo nabo kunye nabanye. Into yokuba ekugqibeleni umgangatho yokudlala akuxhomekekanga iqondo ucinezelo, kunye neemeko ukudlala ngayo, kwakunye nohlobo lomculo.

Hi xikombiso, le ngoma udlalwa kwi itheyiphu rekhoda efakwe kwi imoto ekhaya. Kwimeko enjalo, umgangatho kwi-192 kbit / s kwakwanele. isantya sebhithi ephakamileyo iza kuphucula umgangatho welizwi, kodwa akuyi kuba obonakalayo umahluko ngenxa izinga lengxolo eliphezulu phakathi nohambo. Ukuba umculo idlala kwi computer yakho ekhaya okanye umdlali umculo eziphathwayo, kuthatha ubuncinane 256 kbit / s. Ukuba Oluphawu ayinakho ukutshintsha, ithe yadluliselwa isixhobo sangaphandle sibekwe kumhlathi abizayo amazwe, kufanele kube lula ukuwufumana ucinezelo lincinane. Ngoko ke nangokuxabana bitrate 320 kbit / s.

Bitrate kangangoko izimbo ezahlukeneyo zomculo

Umculo nge isantya sebhithi eliphezulu akusoloko kuyimfuneko. music Popular ngokuqhelekileyo izandi kakhulu kakuhle kwi bitrates ka 192-256 kbit / s. kwizinga eliphezulu zingasetwa, kodwa ingqondo kule: iingoma zomculo wepop siphila ixesha elifutshane, ngoko okusindisa isithuba kwidiski kufuneka ibe ngumba ophambili. Ukongeza, umgangatho erekhodiweyo yokuqala, eliphakathi kakhulu, ngoko ukunyusa izinga bit akakwazi kuchaphazela umgangatho lwefayile sidlalwe. Ukuze uphulaphule zothutho sesikweni amaqela ezisemgangathweni avareji kwanele.

Xa sithetha ngomculo weklasiki, imisebenzi band rock edume okanye iingoma copyright ezinqabileyo, umgangatho kufuneka ibe kakhulu. Xa ukuthenga umculo kufuneka ujonge isantya sebhithi zichaziweyo kwiipakethe disc. Ukuba ingoma elayishelwe ezantsi esuka kwi Internet, olo lwazi kufuneka ibe iyafumaneka kwiphepha kulanda. Ukongeza, izinga bit iyavezwa kwi umdlali udlala.

ividiyo ukufana

Siye okhankanywe ngaphambili ukuba bitrate odiyo. Kodwa yintoni na bitrate ividiyo? Njengoko le vidiyo umva idlalwa kulandelelwano izandi kunye nemifanekiso, le nkcazo bitrate efanayo. Ubukho ividiyo uthotho ifayile nzima, kodwa ekugqibeleni kuba umfanekiso iprosesa - enye iintsapho amaqanda, ezifana izandi. Umgaqo ufihlo iyafana zonke iintlobo lwefayile.
