Opus → FLAC

Hayi, kwaye ixabiso lokuba mnyama: akukho nto ingayenza. I Opus sele ishiye inkcukacha ngexesha lokushicilela kwayo, kwaye ukujika okuseleyo kwi FLAC engalahliyo igcina ngokuchanekileyo oko - akukho ngaphezulu. Ifayile ifumana amaxesha amaninzi amakhulu kwaye ithetha ngokufanayo. Ihlala ihamba kakuhle phambi kohlela, kuba FLAC ayizukongeza udidi lwesibini lweeartefacts xa urhweba ngaphandle. I-FLAC ikunika ukuthembeka kwe-WAV kwisiqingatha sobungakanani, ngee-tags ze-metadata ezifanelekileyo kunye nomsebenzi womnatha ofakwe ngaphakathi, oko kukuthi, ilawula iilayibrari zengoma ezingalahlekiyo. I-Opus ayixhaswa yihardware ekhululekileyo - qiniseka ukuba udlala isoftware kuphela, kwaye ulindele ukuba i-car stereos ayihoyi.

Okumiselweyo 192 kbps kulahleko FLAC; dlula-kwi-lossless FLAC. 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.

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi Opus isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi FLAC 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. I-FLAC yi-Free Lossless Audio Codec, ifomati evulekileyo ukusukela ngo-2001 ecinezela ngaphandle kokususa isampuli enye.

Ewe - susa isiqulathi seefayili se Opus 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.

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

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

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-FLAC codec ekhuselekileyo ye-platform ocacisayo. FLAC ihlala iphindaphindwa amaxesha amaninzi ngaphezu kwefayile elungileyo elahlekile, kwaye inkqubo yendalo yeApple yadibanisa kuphela inkxaso ngoku kwaye ngokungxamisekileyo.

Ewe — iifayile ezilayishwe phezulu Opus 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.

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 Opus -> FLAC igqiba kwimizuzu eyi-6-12 kwinkqubo eqhelekileyo yokuhambisa.

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 FLAC ithetha ukuba ifana ne-Opus (ukungabikho kolahleko) okanye ifana ngokubonakalayo (ukungabikho kolahleko olucacileyo).
