OGG ukuba M4A Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili OGG kwaye umguquli ukhetha M4A i-codec / uthelekiso lwe-bitrate oluhambelana neprofayili yombhali. I-lossless M4A (WAV / FLAC / ALAC) igcina yonke isampuli ngokuchanekileyo; i-lossy M4A (MP3 / AAC / OGG / Opus) imiselwe kwi-192 kbps ebonisa ngokucacileyo imixholo yonke yengoma.

I-M4A ifayili iphela kwi-bitrate enjani?

Okumiselweyo 192 kbps kulahleko M4A; dlula-kwi-lossless M4A. Nciphisa ukuya kwi-320 kbps ukuba ufuna ubukhulu bokungazinzi okulahlekileyo, 128 kbps kunikezelo lwepodcast olukhawulezayo, okanye 96 kbps kumthombo welizwi kuphela apho ifayili encinci ibalulekile ngakumbi kuneenkcukacha zestudio.

Ingaba ukuya ukusuka kwi OGG ukuya kwi M4A kuya kunciphisa ubunjani besandi sam?

Ukuba OGG ilahlekile (MP3, AAC) kwaye M4A ayilahleki (WAV, FLAC), i M4A ayingcono kune OGG — awunakubuyisela ulwazi olusele lulahlekile yi-OGG codec. Ukuba i OGG ayilahleki kwaye M4A iyalahleka, lindele ukuba i M4A encoder iphinde icinezele; kwi-192 kbps ilahleko ayifumaneki kuninzi lweendlebe.

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi OGG isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi M4A isiqulathi seefayili. ID3v2 (MP3), i-Vorbis impendulo (OGG, FLAC), i-MP4 ii-atoms (AAC, M4A), RIFF INFO (WAV), i-iXML i-chunks zonke iimaphu ngokucocekileyo.

Ndingaguqula izigidi zeefayili OGG zibe M4A?

Ewe - susa isiqulathi seefayili se OGG kwifayile kwaye siziqhubekeke ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10s yemizuzu. Ukwakhiwa kwesiqulathi seefayili kugcinwa kwimveliso ye-ZIP.

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

Ngokungagqibekanga ewe (a 48 kHz OGG ivelisa 48 kHz M4A, a 44.1 kHz OGG ivelisa 44.1 kHz M4A). Ukulungelelanisa okuthile — umzekelo, ukunyusa isampuli ye-96 kHz studio masters ukuya kwi-44.1 kHz M4A yokukhupha i-CD, okanye ukunyusa isampuli ye-22 kHz yeposi yelizwi ukuya kwi-44.1 kHz M4A — isampuli-ixabiso lokuhla lisebenzisa umgangatho ophezulu we-SOX-style resamply.

Ndingazilungisa njani ilizwi kwinyathelo OGG ukuya kwi M4A?

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

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

I-MP3 idlala ngokubanzi kwisixhobo ngasinye esiyenziwe kwiminyaka emi-20 edlulileyo. I-AAC idlala kwi-Apple, i-Android, i-Sonos, kunye ne-stereo zemoto zakudala. I-FLAC idlala kwi-Sonos ne-Android ekutshanje, isebenza kakubi kwi-iPods ezidala. I-WAV idlala kuyo yonke into kodwa ifayili ikhulu. Isixhobo-esimiselweyo esithe tyaba sikhetha i-M4A codec ekhuselekileyo ye-platform ocacisayo.

Ingaba ifayili yam OGG ifihlakeleyo ngexesha lokuguqulwa?

Ewe — iifayile ezilayishwe phezulu OGG ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo yesandi. Inkqubo yokuhambisa iqhuba kwihardware esilawulayo ukusuka ekuqaleni ukuya kwisiphelo; akukho nkonzo yeqela lesithathu ifumana ifayili yakho.

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

I-codec efanayo yoku-multiplex (umzekelo. AAC ngaphakathi kwe-M4A -> AAC ngaphakathi kwe-MP4): imizuzwana eyi-10-30. Utshintsho lwe-codec (umzekelo. FLAC -> MP3 okanye WAV -> AAC): ngokuqhelekileyo i-10-20% yobude bomthombo, ngoko ke i-1-iyure OGG -> M4A igqiba kwimizuzu eyi-6-12 kwinkqubo eqhelekileyo yokuhambisa.

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

Akukho tshintsho lokufumana oluzenzekelayo luza kwenzeka ngaphandle kokuba ukhetho lokumisela uguquko luvuliwe. Ukuba uziva utshintsho lomphakamo, umdlali wakho wesandi okanye ilayibrari yemidiya ingasebenzisa iReplayGain okanye utshintsho lokusebenza oluzenzekelayo kwingoma nganye kumdlalo - khubaza oko kwaye i M4A ithetha ukuba ifana ne-OGG (ukungabikho kolahleko) okanye ifana ngokubonakalayo (ukungabikho kolahleko olucacileyo).

Ndingaguqula i-OGG yokukhuphela ukusuka kwi-Bandcamp / SoundCloud ibe yi-M4A?

Ukuba i-OGG ilayishwe ezantsi ingakhuselwanga (akukho DRM), ewe. Iifayili ezisasazwayo ezifihliweyo ze-DRM (i-Spotify ngaphandle kwe-intanethi, i-Apple Music) zifihliweyo kwinqanaba le-bit kwaye azikwazi kuqhubekekiswa. Amacebo okuthengiswa kwe-Bandcamp, ukulayisha ezantsi kwe-SoundCloud, unikezelo lwepodcast, kunye nokulinganisa komsebenzisi wonke aguqulwa ngokucocekileyo kwi-M4A.

OGG

I-OGG Vorbis inika ucinezelo lwesandi olukumgangatho ophezulu olufana nolweMP3 kodwa lukhululekile ngokupheleleyo kwaye luvulelekile.

M4A

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