AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni ifayili AAC?

I-AAC (i-Advanced Audio Coding) yifomathi yokucinezela isandi yedijithali elahlekileyo eyenzelwe ukuba ibe yindlela yokulandela i-MP3.

Ingaba umgangatho sele ulahlekile kwifayili AAC?

Into na leyo ikhowudi yokuqala yagqiba ukuyisusa, ayikwazi ukubuyiselwa. AAC icindezela ngokuyila into ethe indlebe ayizukuyiqaphela - iingoma ezimdaka ezihlala phantsi kwezi zikhulu, ukuphindaphinda kumazantsi okuva - kwaye isuse ngokusisigxina. Kwi bitrate elungileyo engaziwayo kuninzi lwaba bonke. Into engayiyo ibuyiselwa, ngoko ukuguqula kwifomati engalahleki igcina iimeko zangoku kunokuba ibuyisele eyakuqala. I-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba ifakwe ibhotile kuyilo lwestereo.

Kutheni isandi sihlala sivale kwifowuni yam AAC?

Kuba isixhobo sefowuni sikhowudi nge chip kunokuba sikhowudi nge processor, kwaye le yifomati eyenziwe yi silicon. Iinkcukacha zesandi, imifanekiso yevidiyo, kunye nemiyalezo eqingqiweyo yonke ivela kwikhowudi efanayo, nto leyo eyenza ukuba banikezele kwifomati engasebenziyo nento oyenzayo. Idlala kwi Apple hardware ngaphandle kocinga kwaye ifuna ukuguqula kakhulu rhoqo naphi na.

Ingaba umculi, i-albhamu kunye nomfanekiso wesiqulathi seefayili kwi AAC yam uhlala uguqulwa?

Ziyenza apho ifomati yenjongo ikhona indawo yokuzibeka. AAC ithatha iimpawu kunye nomsebenzi womzobi ofakwe ngaphakathi njengenxalenye yefayile, kwaye uguqulelo lukopa ngaphezulu kwendawo nganye eqondayo indawo engqongileyo. Iimpawu ezingaqhotyoshwanga ziyimfuneko - zacaciswa phambi kokuba uphawulo lube lulindeleko oluqhelekileyo kwaye zigcine akukho nto, ngoko ithala leencwadi eliguqulelwe ngendlela lifika njengedonga lweengoma ezingabonakaliyo.

Ingaba i-AAC ifayili iyakwazi ukuthwala i-5.1 surround mix?

Ewe - ifomati iphatha ngaphezulu kweendawo ezimbini zesandi ngokuchanekileyo, ngoko ke uthelekiso olujikelezayo lugcina ubeko lwesandi saso kunokuba luyihlole kwi-stereo kwindlela engaphakathi. Ukuba uthetha ngayo njenge-stereo ixhomekeke kwisiphelo eside: umfumani uya kuqokelela zonke iziqhagamshelanisi, ifowuni iya kuhlambulula ngexesha lokudlala ngaphandle kokungakhathali. Ukutshintsha kwifomati ye-stereo kuphela yenza ukuba uthelekiso luhlale.

Ingaba i-AAC iyadlala ngokuthe ngqo kwiphepha le-web?

Ewe. AAC iphakathi kwefomati zesandi ezimfutshane ezisuka kumkhangeli zincwadi, ngoko ke ingaqhutywa kwinxalenye yesandi okanye kumdlali wepodcast kwaye isebenza kuwo onke amacala ngaphandle koplugin okanye ifayile yokubuyisa. Oku kwenza ukuba ibe yinjongo yoshicilelo olukhuselekileyo, kwaye yiyo loo nto ukuguqula ushicilelo olunobungozi kule fomati kuqhelekileyo indlela efutshane yokufumana idlala kwiwebhusayithi. I-AAC ithetha ngokucacileyo ngakumbi kune-MP3 engaphantsi kwe-128 kbps kwaye yindawo emiselweyo yokulandela umkhondo wesandi kwi-MP4, YouTube, Apple Music kunye nokusasazwa.

Yintoni i-bitrate ekufuneka ndiyiguqulele kwiifayili zam AAC?

Uthelekiso lwendawo ebekwe kuyo, hayi umthombo. Kwingoma, 256 ukuya 320 kbps icacile kuye wonke umntu ofundayo; kwilizwi kunye nepodcasts, 96 ukuya 128 kbps ininzi kwaye iqulethe ifayile kwakhona. Ukunxulumana ngaphezulu komthombo we bitrate kusezantsi isithuba - igcina ngokunyanisekileyo isandi esisele sidlula kwindlela elahlekile kwaye ayibuyiseli nto ikhowudi yokuqala elahlekile.

Ingaba ukusebenzisa i AAC kudinga ilayisenisi yepateni?

Ayikuko kuwe. Ii codecs ezibandakanyiweyo ziquka iindidi zepateni, kwaye ilayisensi ibekwe ngabantu abathutha ii decoders - ifowuni, umkhangeli zincwadi, indlela yokusebenza - ixesha elide phambi kokuba ifayile ifike kuwe. Yiyo loo nto ifomati ikho kuyo yonke ihardware kwaye kutheni i royalty- free efana nayo ikhona, kwaye ayitshintshanga nto malunga nokuguqula ifayile oyinayo.

Ingaba ukutshintshela kutshintsha umyinge wesikhokelo sesandi sam AAC?

Ayinaku ukuba ungacela ukuba ikwenze. Uguqulelo lugcina umyinge wombhalo ophambili - 48 kHz uhlala 48 kHz, 44. 1 kHz uhlala 44. 1 kHz - kuba ukuphinda uthathe isampuli kubiza kakhulu umgangatho oncinci ngaphandle koncedo xa akukho nto ifunayo. Izixabiso ziyanele: ii CD zesandi zifuna 44. 1 kHz, abanye abadlali be hardware abadala bavuma akukho nto enye, kwaye imibhobho yelizwi ifuna 16 kHz. Cwangcisa umyinge ngokucacileyo kwezi meko kwaye uyishiye ikhululekileyo ngaphandle kokuba.

Ndingayinika kwakhona igama elipheleleyo lesiqendu endaweni yokuguqula i AAC?

Akukho nanye, kwaye ifanele ukuqonda kutheni: unikezelo luphawu, ngelixa i bytes ngaphakathi zidityaniswe kwifomati ekhethekileyo. Ukuphinda ubize ifayile ivelisa ifayile igama layo lithembisa into imixholo yayo ayinikezeli, kwaye nantoni na evula ifayile okanye ilahlekile ifayile okanye ifunda ngokungachanekanga. Ukuphela kwendlela efutshane kuhlobo olubini oluyinyani ibhokisi efanayo phantsi kwegama elahlukileyo - kwaye nalapho ukuphinda ubhale ngokuchanekileyo kukhuselekile kunegama elahlukileyo.

Ndingaguqula isiqulathi seefayili esipheleleyo se AAC iifayili ngenye indlela?

Nge akhawunti, ewe - shiya ngaphaya kunye kwaye zifolwa njengemisebenzi enye endaweni yokuphathwa enye ngexesha, ngemimiselo efanayo esetyenziswa kwiqela kunye neziphumo ezibuyiselweyo kunye. Uguqulelo oluzenzekelayo luqhuba ifayile enye ngexesha (izixhobo zokudibanisa zithatha ezimbini); inkqubo ehlawulweyo ivula uqhubekeko lweqela kunye nobukhulu befayile nganye umda, owenza uguqulelo lwefayile yonke yovimba isebenziseke.

Yintoni eyenza i-AAC yam ifile emva kokuguqula?

Icinywa. Ulayisho phezulu kunye nempumelelo eguqulweyo zombini zihlala kumncedisi kuphela kude kube umsebenzi ufuna ukuba zigcinwe kwaye zisuswa ngokuzenzekelayo; unikezelo luya phezulu kwi HTTPS kumgca ngamnye. Akukho mntu ufunda imixholo, akukho nto iqulathe isiqulathi seefayili, kwaye akukho nto igqityiwe komnye umntu. Ukuba awufuni ukulindela ucoci oluzenzekelayo, ukuvala umsebenzi ususa iifayile ngokuzenzekelayo.
