AMR ukuba AIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili AMR kwaye umguquli ukhetha i AIFF codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko AIFF (WAV / FLAC / ALAC) ugcina yonke isampuli nge-bit-identical; ukungabikho kolahleko AIFF (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngokucacileyo kwiinwele ezininzi. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, eyenza imodeli yomsebenzi wokuthetha womntu kunokuba isebenze kwi-audio epheleleyo. I-AIFF igcina i-PCM engacinezelwanga encinci-ephakathi — i-Apple-side elinganayo ne-WAV, nge-bit-per-bit fidelity efanayo.

Ingaba ukutshintsha i-AMR ukuya kwi-AIFF kunyusa umgangatho wesandi?

Hayi, kwaye ixabiso lokuba mnyama: akukho nto ingayenza. I AMR sele ishiye inkcukacha ngexesha lokushicilela kwayo, kwaye ukujika okuseleyo kwi AIFF engalahliyo igcina ngokuchanekileyo oko - akukho ngaphezulu. Ifayile ifumana amaxesha amaninzi amakhulu kwaye ithetha ngokufanayo. Ihlala ihamba kakuhle phambi kohlela, kuba AIFF ayizukongeza udidi lwesibini lweeartefacts xa urhweba ngaphandle. I-AIFF yifomati yotshintshiselwano lwestudio kwi-macOS, iphatha i-metadata kakuhle kune-WAV eqhelekileyo, kwaye ingenisa kwi-Logic ne-Pro Tools ngokukhawuleza. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okungaphezulu kweefrequencies zefowuni, kwaye akukho xabiso lokucofa kwakhona liyibuyisela.

Ndingayiphawula i AIFF ngeenkcukacha zomculi ne-albham?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe AMR, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. AIFF ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla.

Ingaba i AIFF iyadlala kwimoto yam okanye kwizixhobo ezidala?

Ihlala ingasebenzi. AMR ikhowudiwe yiyo yonke into, kubandakanya iyunithi yemoto yomlomo kunye nabadlali abadala; AIFF ifuna isoftware eyaziyo i-codec, eyona hardware ihlala ingekho. Ukuba indawo efanelekileyo yimoto yestereo okanye umdlali ophathekayo, oku kukholelwa kakhulu ukuba uhlala kwi AMR. I-AIFF ikhulu njenge-WAV enesixhaso esibi ngaphandle kwehlabathi le-Apple, ngoko ke kukhetho olubi lokusasaza.

Kutheni umculo uthetha ntoni xa uguqulwa?

Kuba enye icala liyi codec yokuthetha kune codec yengoma. Imodelisa umjelo wokuthetha womntu kwaye ishiya konke ngaphandle kwe bandwidth yefowuni, elungileyo kwimemo yokuthetha kwaye ilahlekile nantoni na enezixhobo kuyo. Ukutshintsha kude nayo akuyi kubuyisela uxinzelelo olulahlekileyo - akufuneki kubekho ukuvulwa kwindawo yokuqala.

I-AIFF ifayili ephumayo izakusebenzisa i-bitrate enjani?

Okumiselweyo yi 192 kbps ye-lossy AIFF; igqityiwe-kwi-lossless AIFF. Nciphisa kwi 320 kbps ye-audiophile okanye 96 kbps yelizwi/podcast. Ukhetho lutshintshiselana ngobungakanani befayili ngokuchasene nobuxoki obunokulungiswa; ngaphantsi kwe-96 kbps i-lossy artifacts ibonakala kwingoma.

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

Ukuba AMR ilahlekile kwaye AIFF ayilahleki (umzekelo MP3 → WAV), i AIFF ayingcono kune AMR — awunakubuyisela ulwazi olusele lulahlekile. Ukuba AMR ayilahleki kwaye AIFF ilahlekile, i AIFF codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kumxholo omkhulu.

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi AMR isiqulathi seefayili kwaye ibhalwe kwi AIFF isiqulathi seefayili apho ifomati ixhasa iithagi. Zonke iziseko eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha ii-tags kakuhle; i-WAV egqityiweyo ayisebenzi. I-AIFF yi-Apple's Audio Interchange File Format ukusukela ngo-1988, ibekwe kwi-IFF chunk design efanayo ne-AVI's RIFF.

Ndingaguqula izigidi zeefayili AMR zibe AIFF?

Ewe - susa isiqulathi seefayili se AMR 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-AIFF iya kugcina inqanaba lesampuli elifanayo njenge-AMR?

Ngokungagqibekanga ewe — 48 kHz AMR ihlala i-48 kHz kwi AIFF. Ukuba ufuna ukunyusa isampuli ukuze ihambelane (96 kHz → 44.1 kHz yokushicilela i-CD), ukhetho lwesampuli-yexabiso lisebenzisa ukuphinda uthathe isampuli esezingeni eliphezulu kwindlela efanayo yokugqitha kwekhowudi.

Ndingazilungisa njani i-loudness xa ndiguqula i-AMR ibe yi-AIFF?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwi AIFF, ukubeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast). Isetyenziswa xa kudityaniswa iingoma ezilawulwa kumanqanaba ahlukeneyo.

Ingaba i-AIFF yam iya kudlala kwi-stereo yemoto, i-iPod, kunye ne-Sonos?

I-MP3 idlala naphi na. I-AAC idlala kwi-Apple, i-Android, ne-Sonos. I-FLAC idlala kwi-Sonos ne-Android kodwa ayiyiku-iPods ezidala. I-WAV idlala naphi na kodwa ikhulu. Isixhobo esiphambili esimiselweyo esithe nkqo sikhetha i-AIFF codec elungelelaniswe kakuhle kwi-hardware yakho emiselweyo.

AMR

I-AMR (I-Adaptive Multi-Rate) yifomathi yocinezelo lwe-audio elungiselelwe ikhowudi yentetho. Iqhele ukusetyenziswa kwiifowuni eziphathwayo ukwenzela ukurekhoda kwelizwi kunye nokudlala kwakhona.
