AMR ukuba AIFF Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

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

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 irhweba ngaphakathi kwi-Logic ne-Pro Tools ngokukhawuleza. I-AMR ibulala umculo: ububanzi besantya sayo esiyi-8 kHz bususa konke okungaphezulu kwesantya sefowuni, kwaye akukho xabiso lokucofa kwakhona olungayibuyisela.

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 isebenzisa i-bitrate enjani?

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

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

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

Ingaba i-AMR ukuya kwi-AIFF 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 AMR kwaye babhalwe kwi AIFF isiqulathi seefayili apho i-AIFF ifomati ixhasa ii-tags. Ukwakhiwa kwencwadi yesandi ye-M4B ijikeleza-jikeleza kwi-M4B ne-AAX → i-M4B i-output.

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 → 48 kHz AIFF). 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 AMR ukuya kwi AIFF?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo lusebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye AIFF, 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-AIFF 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.
