Indlela yokuguqula AC3 ukuba AAC

Inyathelo 1: Layisha eyakho AC3 iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho AAC iifayile

AC3 ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AC3 yesandi kwi-AAC ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayile AC3 kwaye umguquli ukhetha i AAC codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko AAC (WAV / FLAC / ALAC) ugcina yonke isampuli ye-bit- identical; ukungabikho kolahleko AAC (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngaphaya kweendlebe ezininzi. AC-3 yisandi esilahlekileyo esingenasiqhagamshelanisi esininzi, sihlala si-5.1 kwi-384 okanye 448 kbps, nemetadata yonxibelelwano oluqhelekileyo noluphantsi koxinzelelo. I-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba ifakwe ibhotile kuyilo lwestereo.

Ingaba ukutshintsha AC3 ukuya ku AAC kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AAC encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i AAC ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo.

Ndingayiphawula i AAC ngeenkcukacha zomculi ne-albham?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe AC3, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. AAC ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. I-AAC ithetha ngokucacileyo ngakumbi kune-MP3 engaphantsi kwe-128 kbps kwaye yindawo emiselweyo yokulandela umkhondo wesandi kwi-MP4, YouTube, Apple Music kunye nokusasazwa.

I-bitrate yefayili ephumayo AAC iza kusetyenziswa ntoni?

Okungagqibekanga ku 192 kbps kulahleko AAC; dlula- kwi-lossless AAC. Nciphisa ku 320 kbps ku audiophile okanye 96 kbps kulizwi / ipodcast. Ukhetho lurhweba ubungakanani befayile ngokuchasene nobuxoki obuvakalayo; ngaphantsi kwe 96 kbps ulahleko lwee-artefacts zibonakala kwingoma.

Ingaba ukudlula kwi AC3 ukuya kwi AAC kuya kunyusa ubunjani besandi sam?

Ukuba AC3 ilahlekile kwaye AAC ayilahleki (umzekelo MP3 → WAV), i AAC ayingcono kune AC3 — awunakubuyisela ulwazi olusele lulahlekile. Ukuba AC3 ayilahleki kwaye AAC ayilahleki, i AAC codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kuninzi lwezinto eziquletheyo.

Ingaba umguquli AC3 ukuya ku AAC ugcina i-ID3 / i-metadata tags?

Ewe - isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi AC3 isiqulathi seefayili kwaye ibhalwe kwi AAC isiqulathi seefayili apho ifomati ixhasa amaphetshana. Zonke izicelo eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha amaphetshana kakuhle; i-raw WAV ayisebenzi. I-AAC yiNkqubo yoKhuseleko lwesandi esiPhambili, emiselwe ngo-1997 njenge-MPEG-2 Inxalenye ye-7 kwaye icwangciswe ngokucacileyo ukubuyisela i-MP3.

Ndingaguqula izigidi zeefayili AC3 zibe AAC?

Ewe - shiya isiqulathi seefayili se AC3 iifayile ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi emininzi ethe tye kwaye akukho mda wobungakanani befayili nganye, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10 yemizuzu.

Ingaba i AAC iyagcina ixabiso lesampuli elifanayo njenge AC3?

Ngokungagqibekanga ewe — 48 kHz AC3 ihlala 48 kHz kwi AAC. Ukuba ufuna ukunyusa uvavanyo ukuze ulungelelanise (96 kHz → 44.1 kHz ukukhuphela iCD), ukhetho lwesampulu-yesantya lusebenzisa uvavanyo oluphezulu lomgangatho kwindlela efanayo yokugqitha kokukhowuda.

Ndingazilungisa njani i-loudness xa ndiguqula AC3 ukuya ku AAC?

Ewe - ukhetho lokwenza isantya sisebenze ngokuqhelekileyo lusebenzisa ITU-R BS.1770 / EBU R128 ukwenziwa sebenze ngokuqhelekileyo kwi AAC, lujolise kwi -14 LUFS (umgangatho wokudlulisa) okanye -16 LUFS (umgangatho wepodcast). Isetyenziswa xa kuqhutywa iingoma ezimasterwe kumanqanaba ahlukeneyo.

I-AAC ifakwe ipateni, kwaye iqela lee-players ezidala kakhulu zihlala ziyichaza apho bafuna khona i-MP3.

Ingaba i-AC3 yam ifayile ifihlakeleyo ngexesha liguqulwa kwi-AAC?

Ewe — iifayili ezilayishwe phezulu AC3 ziqhubekeka kubasebenzi abamiselweyo kwaye zicinywe ngaphakathi kwemizuzu. Asiyi kudlala kwakhona, sigcine ixesha elide, okanye sinikezele kwizinto eziqulethe isandi. Ifestile yokugcina epheleleyo ikwi /privacy/.

Ithatha ixesha elingakanani ukutshintsha i-1-iyure AC3 ukuya kwi-AAC?

I-codec efanayo ye-re-mux: 10 ukuya kwimizuzu engama-30. Yenza kwakhona ikhowudi kwi-codec eyahlukileyo: iqhelekileyo 10 ukuya kwimizuzu engama-20% yobude bomthombo, ngoko ke i 1-yure AC3 → AAC igqiba kwimizuzu engama-6 ukuya kwezingama-12. Imisebenzi yeqela ihamba ngokufanayo phakathi kwabasebenzisi ukuze ikhawuleze ngakumbi.
