AAC kuya AIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini oyenzayo i-AAC kuya ku-AIFF umguquli womsindo?

AAC sele ilahlekelwa, ngakho ukushintsha ku AIFF kugcina umsindo okhona ngaphandle kokuncipha okuningi, kodwa akukwazi ukubuyisela imininingwane elahlekile ekuqondeni okusemthethweni. AIFF kulungile uma uhlela ukuhlela futhi ugcine kabusha ngaphandle kokuxubana kwezinto ezibonakalayo zokucindezeleka.

Ingabe isilinganiso sesampula kanye nesimo sesixhumi sigcinwa?

Ngephutha yebo — i-stereo ihlala i-stereo, isilinganiso sesampula sakuqala (44.1 kHz, 48 kHz, njll.) sithunyelwe ku-AIFF output.

Ingabe ihele AIFF lizoba likhulu kakhulu kunalo AAC?

Yebo — umsindo ongenawo umonakalo uvame ukuba 5-10x omkhulu kunawo umsindo ongenawo umonakalo ngekhwalithi elinganayo. Phinda ubeke isinqumo se ~10 MB ngomzuzu AIFF versus ~1 MB ngomzuzu we-high-bitrate AAC.

Ingabe i-AIFF ingaphezulu kwe-AAC?

Yebo — izihlungi ezingalahleki zigcina wonke ama-byte. Lindela ukuthi i-AIFF ibe ngu-3-8x ubukhulu be-AAC. Inani elingcono lizoba ukuthi akukho ukulahleka kwekhwalithi engaphezulu ekuhlelani noma ekuphindeni ukungenisa.

Ingabe ukushintsha AAC kuya ku AIFF kuthuthukisa ukhwalithi yomsindo?

Akuna, futhi kufanelekile ukuba kucace: akukho okuzokwenzeka. I AAC idlulele i-detail ngesikhathi sokuqothula kwayo okujwayelekile, futhi ukubopha okushiwo ku AIFF ongeke ulahlekelwa yilutho kugcina lokho - akukho okuningi. Ihele lithola izikhathi eziningi ezikhulu futhi lizwakala lifana. Kukhona ukunyakaza okulungile ngaphambi kokulungisa, ngoba AIFF ngeke ihlanganise isizukulwane sesithathu sezinto ezibonakalayo uma ukhipha. I-AIFF iyifomethi yokushintshana kwestudio ku-macOS, iphatha i-metadata kahle kunaleyo ye-WAV, futhi ingenisa ku-Logic ne-Pro Tools ngokushesha. I-AAC ifakwe ipatenthi, futhi ama-players amasha ambalwa angeke avumeleke lapho befuna khona uku accetta i-MP3.

Yini okushoyo ihele AIFF?

Ibhokisi lemisindo ngaphakathi kwalo, hhayi i-audio ngokwayo. Lo mbhalo ongeziwe uhlala lapho ubude, umbiko wokufuna kanye nanoma yimiphi imininingwane ye-metadata ifomu lichaza khona, ngakho umdlali ungazi ukuthi i AIFF ihlala isikhathi esingakanani ngaphambi kokuqothula ifremu eyodwa endaweni yokuskena ihele lonke ukuze ufunde. Lokhu kusho futhi ukuthi ubukhulu abukwazi ukuxazulula okungaphakathi: amabhokisi amaningi anjalo avunyelwe ukuphatha okungaphezu kwehlobo elinye lomsindo, ngakho amafayela amabili AIFF angasebenza ngendlela ehlukile ngenkathi ebona ngokufana ngaphandle. I-AIFF igcina i-PCM engacindezelwanga enkulu-endian — i-Apple-side elinganayo ne-WAV, nge-bit-for-bit fidelity efanayo.

Kungani ifoni yami noma ithebhulethi irekhoda ku AAC?

Ngenxa yokuthi yilokho okukhiqizwa yi-hardware encoder kwidivayisi. Amamemo omsindo, ukurekhodwa kwesikrini kanye ne-audio track yenoma yini efilmwe kwifoni iphuma njenge AAC ngaphandle komuntu okhetha lokhu, ngakho-ke amafayela amaningi afika kulo futhi kungani ukhwalithi ingcono kunesayizi yefayela ebonisa. Akukho lutho oluzomisa ukuguquka; kusho ukuthi umsuka ukhonjiswa kathathu, yi-chip elungele impilo yebhethri ngaphezu kokungafani. I-AAC iyi-Advanced Audio Coding, ejwayelekile ngo-1997 njenge-MPEG-2 Part 7 futhi ifakwe ngokucacile ukushintsha i-MP3.

Ingabe i-AIFF izodlala emoto yami noma ku-hardware edala?

Ngokuvamile akunjalo. AAC i-decoded yinoma yini, kufaka phakathi iyunithi yemoto kanye nabadlali abadala; AIFF idinga isofthiwe eyazi i-codec, esebenzisa ihardware ehlukile. Uma indawo esiya kuyo imoto ye-stereo noma umdlali ophathekayo, lokhu kuyisinqumo esiqinile sokuhlala ku AAC. I-AIFF ikhulu njenge-WAV futhi inezixhaso ezibi ngaphandle kwe-Apple world, ngakho-ke iyisinqumo esibi sokusakaza.

Ingabe kunelayisense exhunywe ku AAC?

Akuna omunye ongacabanga ngawo. I-codec ifakwe iziqukathi zepatenti, futhi ilayisense ibekwe ngumuntu othumela umbhalo oguquliwe — ifoni, i-browser, i-operating system — isikhathi eside ngaphambi kokuba ifayela lifike kuwe. Lokhu kusho ukuthi ifomu likhona kuwo wonke amahardware, futhi kungani izinketho ezingenazo i-royalty zikhiwa. Akunalutho olushintshayo mayelana nokushintsha ifayela olizithola, futhi kuyimibuzo ephilayo uma uthumela umbhalo oguquliwe wena.

Ingabe AIFF ikhona into efanele ukushintsha?

I-Library yomuntu siqu, yebo; noma yini oyenzayo oyisabalalisa omunye umuntu, cabanga kathathu. AIFF iphumelela ngokukhululekile ngaphandle kokuvala - konke okudlala ngalo namuhla kuzoqhubeka nokudlala ngalo - kodwa amakhodi amasha namadivayisi amasha aqhubeka nokungajwayelekile kokufaka, okuzokwenza umsebenzi ofanayo. Uma ifayela lidinga ukuvulwa kuphela kuma-machines akho, kulungile. Uma lidinga ukuvulwa ku-device ethengiswe eminyakeni emihlanu, khetha enye entsha.

Ingabe kunesikhawulo sobukhulu befayela uma uguqula i-AAC ibe yi-AIFF?

Ukuthunyelwa okungaziwa kuvunyelwe ngokuzenzakalela; ama-akhawunti abhalisiwe amahhala athola umkhawulo ophezulu, futhi ama-akhawunti we-Pro angeke abe ne-limit yefayela ngalinye. Umlando wesiphequluli uvame ukuba ngumkhawulo osebenzayo ngaphambi kokuba umkhawulo wethu we-server-side uqale.

Ingabe ngingenza ukuguqulwa kwe-batch kwefayela le-AAC elilodwa libe yi-AIFF?

Yebo. Thola noma khetha amafayela amaningi we-AAC ku-upload eyodwa — umguquli usebenza ngazo ngokufanayo futhi ubuyisela i-ZIP yemiphumela ye-AIFF. Akunasidingo sokuphinda isikhashana sokufaka ihele ngalinye.
