MP3 ukuba AC3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-MP3 yesandi kwi-AC3 ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayile MP3 kwaye umguquli ukhetha i AC3 codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko AC3 (WAV / FLAC / ALAC) ugcina yonke isampuli ye-bit- identical; ukungabikho kolahleko AC3 (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngaphaya kweendlebe ezininzi. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps. AC-3 yisandi esilahlekileyo esingenasiqhagamshelanisi esininzi, sihlala si-5.1 kwi-384 okanye 448 kbps, nemetadata yonxibelelwano oluqhelekileyo noluphantsi koxinzelelo.

Ingaba ukutshintsha MP3 ukuya ku AC3 kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AC3 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 AC3 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo.

Okungagqibekanga ku 192 kbps kulahleko AC3; dlula- kwi-lossless AC3. 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 MP3 ukuya kwi AC3 kuya kunyusa ubunjani besandi sam?

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

Ingaba umguquli MP3 ukuya ku AC3 ugcina i-ID3 / i-metadata tags?

Ewe - isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi MP3 isiqulathi seefayili kwaye ibhalwe kwi AC3 isiqulathi seefayili apho ifomati ixhasa amaphetshana. Zonke izicelo eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha amaphetshana kakuhle; i-raw WAV ayisebenzi. AC-3 yiDolby Digital, ifomati ejikelezayo emiselweyo yelaserdisc, DVD, ATSC yosasazo kunye nefilimu ekuqaleni kweeminyaka ye-90.

Ndingaguqula izigidi zeefayili MP3 zibe AC3?

Ewe - shiya isiqulathi seefayili se MP3 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 AC3 iyagcina ixabiso lesampuli elifanayo njenge MP3?

Ngokungagqibekanga ewe — 48 kHz MP3 ihlala 48 kHz kwi AC3. Ukuba ufuna ukunyusa uvavanyo ukuze ulungelelanise (96 kHz → 44.1 kHz ukukhuphela iCD), ukhetho lwesampulu-yesantya lusebenzisa uvavanyo oluphezulu lomgangatho kwindlela efanayo yokugqitha kokukhowuda.
