AMR kuya AIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

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

AMR 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 ihele AIFF lizoba likhulu kakhulu kunalo AMR?

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 AMR.

Ingabe ukushintsha AMR kuya ku AIFF kuthuthukisa ukhwalithi yomsindo?

Akuna, futhi kufanelekile ukuba kucace: akukho okuzokwenzeka. I AMR 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-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okuphezulu kwe-frequency yefoni, futhi akukho inani lokuphindeka kokucofa liyibuyisela emuva.

Ingabe ngiyiphawula i AIFF ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo esemthethweni ngaphezulu kwe AMR, engeke ikwazi ukugcinwa kuphi naphi. AIFF ifaka isihloko, umculi, i-album, unyaka, inani le-track kanye ne-incrusted cover art kwibhokisi le-container, ngakho-ke i-music library ifaka ngokulungile ngaphandle kokufaka isandla.

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.

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

Ngokuvamile akunjalo. AMR 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 AMR. I-AIFF ikhulu njenge-WAV futhi inezixhaso ezibi ngaphandle kwe-Apple world, ngakho-ke iyisinqumo esibi sokusakaza.

Ingabe kunelayisense exhunywe ku AMR?

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.

Kungani umculo uzwakala ubuhlungu kulo mguquko?

Ngenxa yokuthi ingxenye eyodwa iyi-codec yokuxoxa hhayi i-codec yomculo. Imodelisa i-human vocal tract futhi isusa konke ngaphandle kwe-bandwidth yefoni, elungile ku-voice memo futhi ebulalayo kunoma yini enezithuluzi ngaphakathi. Ukushintshana eduze kwayo akukwazi ukubuyisela ama-frequencies angekho — angeke abhalwe ngokucophelela endaweni yokuqala.

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

Ukuguquka okumahhala kunesilinganiselo sobukhulu sehele ngalinye, esisetshenzisiwe ngohlobo lwehele, futhi ikhasi lizokutshela uma ihele lidlula kulo. Iphrojekthi ekhokhelwayo isusa lesi silinganiselo, ngakho amafayela amakhulu angaguqulwa.

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

Amafayela amaningi emisebenzini eyodwa adinga iphrojekthi ekhokhelwa. Ukusetshenziswa okumahhala kuyisifayela esisodwa ngasinye sokuguqulwa, ukuguqulwa okufanayo ngehora. Kuphrojekthi ekhokhelwa ungangeza amafayela amaningi kumsebenzi owodwa, bese ulanda impendulo ngayinye yayo noma zonke ku-ZIP eyodwa.

Yini ezoba namafayela ami AMR ngemuva kokuguqulwa?

Amafayela alayishwe phezulu aphathwa kumaseva ethu okuguqula, akukho muntu obhekana nawo, futhi ahlukaniswe. Ukufaka kanye nohele oluguqulwe kususwa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa, okushiya isikhathi sokulanda imiphumela. Bona /privacy/ ukuphoqa okuphelele.

Yini izinhlelo ezidlala ihele AIFF?

AIFF idlala emidlalweni emikhulu yomculo, iziphequluli, nama-media library. I-iTunes / Apple Music, VLC, Foobar2000, nama-phone media apps aphatha lokhu ngokusemthethweni.
