AIFF ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AIFF yesandi ibe yi-AAC ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili AIFF kwaye umguquli ukhetha AAC i-codec / uthelekiso lwe-bitrate oluhambelana neprofayili yombhali. I-lossless AAC (WAV / FLAC / ALAC) igcina yonke isampuli ngokuchanekileyo; i-lossy AAC (MP3 / AAC / OGG / Opus) imiselwe kwi-192 kbps ebonisa ngokucacileyo imixholo yonke yengoma. I-AIFF igcina i-PCM engacinezelwanga encinci-ephakathi — i-Apple-side elinganayo ne-WAV, nge-bit-per-bit fidelity efanayo. I-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba iboniswe kwi-stereo design.

Ingaba ndilahlekelwe yintoni ngokuguqula i AIFF ibe yi AAC?

Ezinye, kwaye zihlala zikhona - le yindawo enye apho ulwazi luza kuthuthwa khona. AIFF igcina yonke imilinganiselo ngokuchanekileyo; AAC 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 AAC.

I-AAC ifayili iphela kwi-bitrate enjani?

Okumiselweyo 192 kbps kulahleko AAC; dlula-kwi-lossless AAC. Nciphisa ukuya kwi-320 kbps ukuba ufuna ubukhulu bokungazinzi okulahlekileyo, 128 kbps kunikezelo lwepodcast olukhawulezayo, okanye 96 kbps kumthombo welizwi kuphela apho ifayili encinci ibalulekile ngakumbi kuneenkcukacha zestudio.

Ingaba ukuya ukusuka kwi AIFF ukuya kwi AAC kuya kunciphisa ubunjani besandi sam?

Ukuba AIFF ilahlekile (MP3, AAC) kwaye AAC ayilahleki (WAV, FLAC), i AAC ayingcono kune AIFF — awunakubuyisela ulwazi olusele lulahlekile yi-AIFF codec. Ukuba i AIFF ayilahleki kwaye AAC iyalahleka, lindele ukuba i AAC encoder iphinde icinezele; kwi-192 kbps ilahleko ayifumaneki kuninzi lweendlebe.

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi AIFF isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi AAC isiqulathi seefayili. ID3v2 (MP3), i-Vorbis impendulo (OGG, FLAC), i-MP4 ii-atoms (AAC, M4A), RIFF INFO (WAV), i-iXML i-chunks zonke iimaphu ngokucocekileyo. I-AAC yiNkqubo yoKhuseleko lwesandi esiPhambili, emiselwe ngo-1997 njenge-MPEG-2 Inxalenye ye-7 kwaye icwangciswe ngokucacileyo ukubuyisela i-MP3.

Ndingaguqula izigidi zeefayili AIFF zibe AAC?

Ewe - susa isiqulathi seefayili se AIFF kwifayile kwaye siziqhubekeke ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10s yemizuzu. Ukwakhiwa kwesiqulathi seefayili kugcinwa kwimveliso ye-ZIP.

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

Ngokungagqibekanga ewe (a 48 kHz AIFF ivelisa 48 kHz AAC, a 44.1 kHz AIFF ivelisa 44.1 kHz AAC). Ukulungelelanisa okuthile — umzekelo, ukunyusa isampuli ye-96 kHz studio masters ukuya kwi-44.1 kHz AAC yokukhupha i-CD, okanye ukunyusa isampuli ye-22 kHz yeposi yelizwi ukuya kwi-44.1 kHz AAC — isampuli-ixabiso lokuhla lisebenzisa umgangatho ophezulu we-SOX-style resamply.

Ndingazilungisa njani ilizwi kwinyathelo AIFF ukuya kwi AAC?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye AAC, ibeka i- -14 LUFS (isiqhelo sokusasaza) okanye i- -16 LUFS (isiqhelo sepodcast) okanye ixabiso elimiselweyo. Isetyenziswa xa kutshintshwa iingoma ngemiphakamo emininzi yolawulo kwi-AAC yoluhlu lokudlala.

Ingaba i-AAC iya kudlala kwi-stereo yemoto yam / i-iPod / i-Sonos / isithethi se-Bluetooth?

I-MP3 idlala ngokubanzi kwisixhobo ngasinye esiyenziwe kwiminyaka emi-20 edlulileyo. I-AAC idlala kwi-Apple, i-Android, i-Sonos, kunye ne-stereo zemoto zakudala. I-FLAC idlala kwi-Sonos ne-Android ekutshanje, isebenza kakubi kwi-iPods ezidala. I-WAV idlala kuyo yonke into kodwa ifayili ikhulu. Isixhobo-esimiselweyo esithe tyaba sikhetha i-AAC codec ekhuselekileyo ye-platform ocacisayo. 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-AAC ifakwe ipateni, kwaye iqela lee-players ezidala kakhulu zihlala ziyichaza apho bafuna khona i-MP3.

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. Inkqubo yokuhambisa iqhuba kwihardware esilawulayo ukusuka ekuqaleni ukuya kwisiphelo; akukho nkonzo yeqela lesithathu ifumana ifayili yakho.

Ithatha ixesha elingakanani ukutshintsha i-AIFF yeyure enye ibe yi-AAC?

I-codec efanayo yoku-multiplex (umzekelo. AAC ngaphakathi kwe-M4A -> AAC ngaphakathi kwe-MP4): imizuzwana eyi-10-30. Utshintsho lwe-codec (umzekelo. FLAC -> MP3 okanye WAV -> AAC): ngokuqhelekileyo i-10-20% yobude bomthombo, ngoko ke i-1-iyure AIFF -> AAC igqiba kwimizuzu eyi-6-12 kwinkqubo eqhelekileyo yokuhambisa.

Kutheni i-AAC ifayili inamandla okanye ipholile kune-AIFF imvelaphi?

Akukho tshintsho lokufumana oluzenzekelayo luza kwenzeka ngaphandle kokuba ukhetho lokumisela uguquko luvuliwe. Ukuba uziva utshintsho lomphakamo, umdlali wakho wesandi okanye ilayibrari yemidiya ingasebenzisa iReplayGain okanye utshintsho lokusebenza oluzenzekelayo kwingoma nganye kumdlalo - khubaza oko kwaye i AAC ithetha ukuba ifana ne-AIFF (ukungabikho kolahleko) okanye ifana ngokubonakalayo (ukungabikho kolahleko olucacileyo).
