AMR ukuba M4A Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

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

I-M4A ifayili isebenzisa i-bitrate enjani?

Okwendalo 192 kbps ye-lossy M4A; idlula-kwi-lossless M4A. Nciphisa kwi-320 kbps ye-audiophile okanye kwi-96 kbps yelizwi/podcast. Ukhetho lutshintshiselana ngobungakanani befayili ngokuchasene nobuxoki obunokulungiswa kwi-bitrates ephantsi kakhulu.

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

Ukuba AMR ilahlekile kwaye M4A ayilahleki (umzekelo MP3 → WAV), ifayili M4A ayingcono kune AMR — awunakubuyisela ulwazi olusele luthunyelwe. Ukuba AMR ayilahleki kwaye M4A ilahlekile, lindele ukuba i-M4A codec iphinde icinezele; kwi-192 kbps oku kucacile kuninzi lwezinto eziquletheyo.

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, imifanekiso ye-albham ifundwa kwi AMR kwaye ibhalwe kwi M4A isiqulathi seefayili (lapho i-M4A ixhasa i-tags, eyenza zonke eziqhelekileyo).

Ndingaguqula izigidi zeefayili AMR zibe M4A?

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-M4A iya kugcina inqanaba lesampuli elifanayo njenge-AMR?

Ngokungagqibekanga ewe (48 kHz AMR → 48 kHz M4A). 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 M4A?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye M4A, ibeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast). Isetyenziswa xa kutshintshwa iingoma ngemiphakamo emininzi yolawulo.

Ingaba i-M4A iya kudlala kwi-stereo yemoto yam / i-iPod / i-Sonos?

I-MP3 idlala kwihlabathi liphela. I-AAC idlala kwi-Apple, i-Android, i-Sonos. I-FLAC idlala kwi-Sonos ne-Android, incinci kakhulu kwi-iPods edala. I-WAV idlala kuyo yonke into kodwa ikhulu. Iinketho eziphambili ziquka isixhobo esimiselweyo kwezi zinjongo eziqhelekileyo.

Ingaba ifayili yam AMR ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu AMR ziqhubekekiswa kubasebenzi abamiselweyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise okuqulethwe sisiqulatho sesandi.

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

I-codec efanayo ye-re-mux: 10-30 imizuzwana. Yenza kwakhona ikhowudi kwi-codec eyahlukileyo: ngokuqhelekileyo 10-20% yobude bomthombo, ngoko ke i-1-iyure AMR → M4A igqiba kwimizuzu eyi-6-12.

Kutheni i-M4A ifayili inamandla / ipholile kune-AMR imvelaphi?

Akukho tshintsho lokufumana oluzenzekelayo luza kwenzeka ngaphandle kokuba uvule ukhetho lokumisela ngokuqhelekileyo. Ukuba ubona utshintsho lomphakamo, umdlali wakho wesandi okanye ilayibrari yemidiya inokuba isebenzisa ukuphinda udlala ukufumana kwakhona okanye ukulungisa i-track nganye kukudlala — hayi nathi.

Ndingaguqula i AMR i-streaming downloads kwi M4A?

Ukuba i-AMR ilayishwe ezantsi ingakhuselwanga (akukho DRM), ewe. Iifayili ezisasazwayo ezifihliweyo nge-DRM (i-Spotify, i-Apple Music) zifihliweyo kwinqanaba le-bit kwaye asikwazi ukuziqhubekekisa. Amacebo e-Bandcamp, ukulayisha i-SoundCloud, kunye nokulinganisa kobuqu buguqulwa kakuhle.
