AIFF ukuba AC3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AIFF yesandi ibe yi-AC3 ngaphandle kokulahleka komgangatho?

Layisha phezulu ifayili AIFF kwaye umguquli wethu ukhetha AC3 i-codec / uthelekiso lwe-bitrate oluhambelana nomcebo. Isiphelo esingalahliweyo (AC3 = WAV / FLAC / ALAC) sigcina yonke isampuli; isiphelo esilahliweyo (AC3 = MP3 / AAC / OGG) simiselwe kwi-192 kbps ebonisa iincwadi zelizwi ezithethayo kunye nemidlalo emininzi.

Ingaba ndilahlekelwe yintoni ngokuguqula i AIFF ibe yi AC3?

Ezinye, kwaye zihlala zikhona - le yindawo enye apho ulwazi luza kuthuthwa khona. AIFF igcina yonke imilinganiselo ngokuchanekileyo; AC3 isusa into eyenza imodeli ye psychoacoustic ilindele ukuba awuzukuyiva. Kwi 192 kbps nangaphezulu loo lindeleko kulungile ngokwaneleyo ukuba icacile kwizinto ezininzi nezixhobo ezininzi. Gcina i AIFF njengenkosi yakho, kuba awunakubuyela kuyo ukusuka kwi AC3. I-AIFF igcina i-PCM engacinezelwanga encinci-ephakathi — i-Apple-side elinganayo ne-WAV, nge-bit-per-bit fidelity efanayo. AC-3 yisandi esilahlekileyo esingenasiqhagamshelanisi esininzi, sihlala si-5.1 kwi-384 okanye 448 kbps, nemetadata yonxibelelwano oluqhelekileyo noluphantsi koxinzelelo.

Ingaba izihloko zam zengoma kunye nemifanekiso ye-albham iya kuqhubeka iphila kwi AIFF ukuya kwi AC3 uguqulo?

Ayiqhelekanga. AIFF ihambisa i-metadata efanelekileyo, kodwa AC3 ayinandawo eqhelekileyo yomsebenzi womculi, i-albham, inani lengoma okanye ubugcisa besiqhoboshelo, ngoko ke iimpawu zilahliwe endaweni yokulahleka. Gcina i AIFF njengekopi ephawulweyo, okanye uphinde uphawule emva koko ngesixhobo njenge Mp3tag okanye iMusicBrainz Picard. AC-3 ayisebenzi kakuhle ngemigangatho yangoku kwaye ayivunyelwanga ziibrowser, iifowuni okanye abadlali abaninzi bewebhu ngaphandle kokuqhekeka phantsi kwestereo.

I-AC3 ifayili isebenzisa i-bitrate enjani?

Okumiselweyo yi-192 kbps ye-lossy AC3; igqityiwe-kwi-lossless AC3. Nciphisa kwi-320 kbps ye-audiophile okanye 64-96 kbps ye-audiobooks yegama elithethayo (elibonisa ngaphaya lelizwi, liphelisa ubungakanani befayili).

Ingaba ukutshintsha ukusuka ku AIFF ukuya ku AC3 kuya kunyusa ubunjani besandi sam?

Ukuba AIFF ilahlekile kwaye AC3 ayilahleki (umzekelo MP3 → WAV), ifayili AC3 ayingcono kune AIFF — awunakubuyisela ulwazi olusele luthunyelwe. Ukuba AIFF ayilahleki kwaye AC3 ilahlekile, lindele ukuba i-AC3 codec iphinde icinezele; kwi-192 kbps oku kucacile kuninzi lwezinto eziquletheyo.

Ingaba i-AIFF ukuya kwi-AC3 igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, kunye nabaphawuli besiqendu (ababalulekileyo kwiincwadi zesandi) bafundwa ukusuka kwi AIFF kwaye babhalwe kwi AC3 isiqulathi seefayili apho i-AC3 ifomati ixhasa ii-tags. Ukwakhiwa kwencwadi yesandi ye-M4B ijikeleza-jikeleza kwi-M4B ne-AAX → i-M4B i-output.

Ndingaguqula izigidi zeefayili AIFF zibe AC3?

Ewe - susa isiqulathi seefayili se AIFF ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba iphele kwimizuzu emininzi.

Ingaba i-AC3 iya kugcina inqanaba lesampuli elifanayo njenge-AIFF?

Ngokungagqibekanga ewe (48 kHz AIFF → 48 kHz AC3). Ukuba ufuna ukunyusa isampulu ukuhambelana (umzekelo. 96 kHz → 44.1 kHz yokushicilela i-CD) ukhetho lwesampulu-yexabiso eliphambili yenza oku ngesampulu ephezulu yomgangatho.

Ndingazilungisa njani ilizwi kwinyathelo AIFF ukuya kwi AC3?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo lusebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye AC3, ibeka i- -14 LUFS (isiqhelo sokusasaza), -16 LUFS (isiqhelo sepodcast), okanye -23 LUFS (isiqhelo sencwadi enesandi). Isetyenziswa xa kuguqulwa iingoma ngemiphakamo emininzi yolawulo.

Ingaba i-AC3 iyadlala kwi-iPod / i-app yencwadi enesandi?

I-MP3 idlala kwihlabathi liphela. I-AAC idlala kwi-Apple, i-Android, i-Sonos. I-FLAC idlala kwi-Sonos ne-Android, isebenza kakuhle kwi-iPods edala. Iincwadi zesandi ze-M4B zidlala ngesahluko sokuhamba kwi-iOS Books, i-Audiobookshelf, kunye ne-Smart Audiobook Player. Iinketho eziphambili ziquka i-preset yesixhobo.

Ingaba ifayili yam AIFF ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu AIFF ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo yesandi. Kubalulekile ngakumbi xa usebenza neelayibrari zencwadi yesandi yobuqu.

Ithatha ixesha elingakanani ukutshintsha i-audiobook ye-10-iyure AIFF ukuya kwi-AC3?

I-codec efanayo-i-re-mux: 10-30 imizuzwana. I-re-encode kwi-codec eyahlukileyo: iqhelekileyo 10-20% yobude bomthombo, ngoko ke i-audiobook yeyure ezi-10 igqiba kwimizuzu eyi-60-120. Abaphawuli besihloko baphila kwi-round-trip kwaye bahlukaniswe ngokucocekileyo.
