M4A ukuba AC3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-M4A yesandi ibe yi-AC3 ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili M4A kwaye umguquli ukhetha AC3 i-codec / uthelekiso lwe-bitrate oluhambelana nomcebo. Isiphelo esingalahliweyo (AC3 = WAV / FLAC / ALAC) sigcina isampuli nganye; isiphelo esilahliweyo (AC3 = MP3 / AAC / OGG / Opus) simiselwe kwi-192 kbps ebonisa ngaphaya kweendlebe ezininzi.

I-AC3 ifayili isebenzisa i-bitrate enjani?

Okumiselweyo 192 kbps ye-lossy AC3; idlula-kwi-lossless AC3. Nciphisa ukuya kwi-320 kbps ye-audiophile, 256 kbps ye-high-quality music, okanye i-96 kbps yelizwi/podcast. Ukhetho lutshintshisa ubungakanani befayili ngokuchasene nobuxoki obunokulungiswa kwi-bitrates ephantsi kakhulu.

Ingaba ukutshintsha ukusuka ku M4A ukuya ku AC3 kuya kunyusa ubunjani besandi sam?

Ukuba M4A ilahlekile kwaye AC3 ayilahleki (umzekelo MP3 → WAV), ifayili AC3 ayingcono kune-M4A - awunakubuyisela ulwazi olulahlekileyo oluthunyelwe yi-encoding elahlekile yokuqala. Ukuba M4A ayilahleki kwaye AC3 ayilahleki, lindele ukuba i-AC3 codec iphinde icinezele; kwi-192 kbps oku kucacile kuzo zonke izinto.

Ingaba i-M4A ukuya kwi-AC3 igcina i-ID3 / i-metadata tags?

Ewe - isihloko, umculi, i-albham, unyaka, inani lengoma, imifanekiso ye-albham efakwe ngaphakathi ifundwa kwi M4A isiqulathi seefayili kwaye ibhalwe kwi AC3 isiqulathi seefayili (ifomati nganye yesandi eqhelekileyo ixhasa iziphawuli). Iziphawuli ziyaphila nokuba i-codec ephantsi itshintsha.

Ndingaguqula izigidi zeefayili M4A zibe AC3?

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. Iimpawu kunye nokwakhiwa kwesiqulathi seefayili zigcinwa.

Ingaba i-AC3 iya kugcina inqanaba lesampuli elifanayo njenge-M4A?

Ngokungagqibekanga ewe — 48 kHz M4A → 48 kHz AC3, 96 kHz → 96 kHz. Ukuba ufuna ukunyusa isampuli ukuhambelana (96 kHz studio masters → 44.1 kHz for CD burning), ukhetho lwesampuli-yexabiso eliphambili lusebenzisa isampuli ephezulu-yexabiso (libsoxr okanye sox-elinganayo) ngaphandle kokubonwa kwe-alias.

Ndingazilungisa njani ilizwi kwinyathelo M4A ukuya kwi AC3?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo lusebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye AC3, ibeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast). Isetyenziswa xa kutshintshwa iqela lelayibrari edityanisiweyo apho imikhondo ineemphakamo zokuphatha ezitshintshayo.

Ingaba i-AC3 iya kudlala kwi-stereo yemoto yam, i-iPod, okanye i-Sonos?

I-MP3 idlala ngokubanzi kwisixhobo ngasinye esidityanisiweyo kwiminyaka emi-20 edlulileyo. I-AAC idlala kwi-Apple, i-Android, ne-Sonos. I-FLAC idlala kwi-Sonos, i-Android, nezixhobo eziphambili zemoto eziphambili; zisebenza kakuhle kakhulu kwi-iPods ezidala. I-WAV idlala kuyo yonke into kodwa ikhulu. Ukhetho lwesixhobo esimiselweyo lukhetha i-AC3 codec ekhuselekileyo yenjongo.

Ingaba ifayili yam M4A ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu M4A ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu embalwa emva kokuphela. Asiyi kudlala, sigcine, sisebenzise i-fingerprint, okanye sisebenzise imixholo yesandi. Ifestile epheleleyo yokugcina i-data ibhalwe kwi /privacy/.

Ithatha ixesha elingakanani ukutshintsha i-M4A yeyure enye ibe yi-AC3?

I-codec efanayo yoku-multiplex (umzekelo, i-FLAC ijikeleza ngaphakathi komgcini weefayili enye itshintshwa kwenye): 10-30 imizuzwana. Yenza kwakhona i-encoding kwi-codec eyahlukileyo: ngokuqhelekileyo 10-20% yobude bomthombo, ngoko ke i-1-iyure M4A → AC3 igqiba kwimizuzu eyi-6-12.

Kutheni i-AC3 ifayili inamandla okanye ipholile kune-M4A imvelaphi?

Akukho tshintsho lokufumana oluzenzekelayo luza kwenzeka ngaphandle kokuba uyenze ngokucacileyo ukhetho lokutshintsha. Ukuba ubona utshintsho lomphakamo kwixesha lokudlala, umdlali wakho wesandi okanye ilayibrari yemidiya ingasebenzisa iReplayGain okanye utshintsho lomlinganiselo lwengoma nganye kwi-i-yodwa — leyo ngumdlali, hayi i-pipeline yethu.

Ndingaguqula i M4A i-streaming downloads kwi AC3?

Ukuba i-M4A ilayishwe ezantsi ingakhuselwanga (akukho DRM), ewe. Iifayili ezisasazwayo ezifihliweyo nge-DRM (i-Spotify ngaphandle kwe-intanethi, i-Apple Music) zifihliweyo kwinqanaba le-byte kwaye asikwazi ukuzikhupha okanye ukuziqhubekekisa. Amacebo e-Bandcamp, i-SoundCloud, i-archive.org, kunye nokulinganisa kobuntu buguqulwa ngaphandle kwengxaki.

M4A

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