AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni i-AAC yefayili yesandi?

I-AAC yifomati yesandi elahlekile. Umkhokeli ususa ukuphindaphinda okungalunganga kunye nesandi esifihlakeleyo ukufezekisa ubungakanani befayili emalunga neshumi le-elinganayo engacinezelwanga. Ukubuyisela ukukhowuda i-AAC kwifomati enye elahlekile kwenza ukuba umgangatho ulahleke; uguqule ukusuka kumphathi ongalunganga xa kunokwenzeka. I-AAC yifomati yesandi ye-Apple ephambili kwaye imiselwe kwiinkqubo ezininzi ze-iOS kubandakanya iVoice Memos nenkqubo yeMusic.

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 iboniswe kwi-stereo design.

Kutheni le nto ifowuni yam igcina konke njenge AAC?

Kuba isixhobo sefowuni sikhowudisa nantoni na eyenza ichip yayo kwihardware, kwaye AAC yiyo loo silicon yakhiwa kuyo. Inkqubo yekhamera ayifuni umbuzo - ibhala ifomati yesixhobo esikwaziyo ukuvelisa kwinqanaba le-frame epheleleyo ngaphandle kobushushu. Ukutshintsha emva koko kuqhelekileyo kwaye akubiza nto kwixabiso lomgangatho ukuba ukhetha injongo egcina umthwalo ofanayo. I-AAC yiNkqubo yoKhuseleko lwesandi esiPhambili, emiselwe ngo-1997 njenge-MPEG-2 Inxalenye ye-7 kwaye icwangciswe ngokucacileyo ukubuyisela i-MP3.

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 kucoda zonke iindawo zesandi, 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 ndiyiguqule iifayile 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. Ukukhowuda ngaphezulu komthombo we bitrate kusezantsi kwesithuba - 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 i-AAC ilahlekile okanye ayilahleki?

Yintoni endingayenza ukuba ndiguqule i-AAC ibe yi-AAC yokwabelana?

Ukuthumela i-imeyili kunye nokwabelana ngemithombo yeendaba, guqula i-AAC ibe yi-MP3 — ukudlala okubanzi kunye nobungakanani befayili encinci. Ukwabelana ngokuthembekileyo nabani na odlala umculo, guqula ibe yi-FLAC okanye i-WAV ukuze ugcine umgangatho ophambili.
