Indlela yokuguqula M4A ukuba AAC

Inyathelo 1: Layisha eyakho M4A iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

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

M4A ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili M4A kwaye umguquli ukhetha i AAC codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko AAC (WAV / FLAC / ALAC) ugcina yonke isampuli nge-bit-identical; ukungabikho kolahleko AAC (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngokucacileyo kwiinwele ezininzi.

I-AAC ifayili ephumayo izakusebenzisa i-bitrate enjani?

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

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

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi M4A isiqulathi seefayili kwaye ibhalwe kwi AAC isiqulathi seefayili apho ifomati ixhasa iithagi. Zonke iziseko eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha ii-tags kakuhle; i-WAV egqityiweyo ayisebenzi.

Ndingaguqula izigidi zeefayili M4A zibe AAC?

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

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

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

Ingaba i-AAC 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-AAC codec elungelelaniswe kakuhle kwi-hardware yakho emiselweyo.

Ingaba ifayili yam M4A ifihlakeleyo ngexesha lokuguqulwa ukuya kwi AAC?

Ewe — iifayile ezilayishwe phezulu M4A 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-M4A yeyure enye ibe yi-AAC?

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 M4A → AAC igqiba kwimizuzu emi-6 ukuya kwi-12. Imisebenzi yeqela ihamba ngokufanayo phakathi kwabasebenzayo ukuphucula isantya.

Kutheni i-AAC inamandla okanye ipholile kune-M4A?

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 AAC.

Ndingaguqula i M4A i-downloads ukusuka kwiinkonzo zokudlulisa ukuya kwi AAC?

I-Bandcamp, i-SoundCloud downloads, urekhodo lwabucala, kunye neefayili zepodcast ziguqulwa ngokucocekileyo.

M4A

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