Indlela yokuguqula AIFF ukuba M4A

Inyathelo 1: Layisha eyakho AIFF iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho M4A iifayile

AIFF ukuba M4A Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AIFF yesandi ibe yi-M4A ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili AIFF kwaye umguquli ukhetha i M4A codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko M4A (WAV / FLAC / ALAC) ugcina yonke isampuli nge-bit-identical; ukungabikho kolahleko M4A (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngokucacileyo kwiinwele ezininzi. I-AIFF igcina i-PCM engacinezelwanga encinci-ephakathi — i-Apple-side elinganayo ne-WAV, nge-bit-per-bit fidelity efanayo. I-M4A igcina i-AAC kwiziganeko ezininzi, okanye i-Apple Lossless (ALAC) xa ivela kwi-rip engalahlekiyo.

Ingaba ndilahlekelwe yintoni ngokuguqula i AIFF ibe yi M4A?

Ezinye, kwaye zihlala zikhona - le yindawo enye apho ulwazi luza kuthuthwa khona. AIFF igcina yonke imilinganiselo ngokuchanekileyo; M4A 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 M4A.

I-M4A ifayili ephumayo izakusebenzisa i-bitrate enjani?

Okumiselweyo yi 192 kbps ye-lossy M4A; igqityiwe-kwi-lossless M4A. 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 AIFF ukuya ku M4A kuya kunyusa ubunjani besandi sam?

Ukuba AIFF ilahlekile kwaye M4A ayilahleki (umzekelo MP3 → WAV), i M4A ayingcono kune AIFF — awunakubuyisela ulwazi olusele lulahlekile. Ukuba AIFF ayilahleki kwaye M4A ilahlekile, i M4A codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kumxholo omkhulu.

Ingaba i-AIFF ukuya kwi-M4A igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi AIFF isiqulathi seefayili kwaye ibhalwe kwi M4A isiqulathi seefayili apho ifomati ixhasa iithagi. Zonke iziseko eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha ii-tags kakuhle; i-WAV egqityiweyo ayisebenzi. I-M4A yi-MP4 equlethe i-audio kuphela, kwaye yiyo into eyenza i-iTunes, i-Apple Music kunye ne-iPhone Voice Memos app.

Ndingaguqula izigidi zeefayili AIFF zibe M4A?

Ewe - susa isiqulathi seefayili se AIFF 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-M4A iya kugcina inqanaba lesampuli elifanayo njenge-AIFF?

Ngokungagqibekanga ewe — 48 kHz AIFF ihlala i-48 kHz kwi M4A. 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-AIFF ibe yi-M4A?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwi M4A, ukubeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast). Isetyenziswa xa kudityaniswa iingoma ezilawulwa kumanqanaba ahlukeneyo.

Ingaba i-M4A 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-M4A codec elungelelaniswe kakuhle kwi-hardware yakho emiselweyo. I-M4A igcina i-data ye-meta eninzi ye-iTunes-style, izihloko kunye nomsebenzi womzobi okhuselekileyo, kwaye yifomati yesandi esemthethweni kwisixhobo se-Apple. M4A ifihla izinto ezimbini ezihlukileyo eziphambili kwesinye isiqalo — lossy AAC kunye lossless ALAC — kwaye i-Apple engasebenziyo hardware inkxaso ayihambelani.

Ingaba ifayili yam AIFF ifihlakeleyo ngexesha lokuguqulwa ukuya kwi M4A?

Ewe — iifayile ezilayishwe phezulu AIFF ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala kwakhona, sigcine ixesha elide, okanye sisebenzise imixholo yesandi. Ifestile yokugcina epheleleyo ikwi /privacy/.

Ithatha ixesha elingakanani ukutshintsha i-AIFF yeyure enye ibe yi-M4A?

I-codec efanayo ye-re-mux: 10 ukuya kwi-30 imizuzwana. Yenza kwakhona ikhowudi kwi-codec eyahlukileyo: ngokuqhelekileyo 10 ukuya kwi-20% yobude bomthombo, ngoko ke i-1-iyure AIFF → M4A igqiba kwimizuzu emi-6 ukuya kwi-12. Imisebenzi yeqela ihamba ngokufanayo phakathi kwabasebenzayo ukuphucula isantya.

Kutheni i-M4A inamandla okanye ipholile kune-AIFF?

Akukho tshintsho lokufumana oluzenzekelayo luza kwenzeka ngaphandle kokuba uvule ukhetho lokumisela ngokuqhelekileyo. Ukuba ubona utshintsho lomphakamo, umdlali wakho wesandi okanye ilayibrari yemidiya inokuba isebenzisa iReplayGain okanye ulawulo oluqhelekileyo lwe-track nganye kukudlala — hayi kuthi. Sukwenza oko ukuze uzive amanqanaba asemthethweni M4A.

AIFF

I-AIFF (i-Audio Interchange File Format) yifomathi yefayile yeaudio engaxinzelelwanga edla ngokusetyenziswa kwimveliso yomsindo kunye nomculo.

M4A

I-M4A yifomati yefayile yomsindo esondeleleneyo neMP4. Ibonelela ngoxinzelelo oluphezulu lweaudio ngenkxaso yemetadata, iyenza ilungele usetyenziso olwahlukeneyo.
