AC3 ukuba Opus Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni eyenza i-AC3 ukuya kwi-OPUS iguquli sesandi?

It re-encodes a AC3 audio file as OPUS. Sample rate and channel count are preserved; the difference is the codec and container.

Ingaba inqanaba lesampuli kunye nobeko lwesiqhagamshelanisi ziya kugcinwa?

Ngokungagqibekanga ewe — i-stereo ihlala i-stereo, i-sample rate emiselweyo (44.1 kHz, 48 kHz, njl.njl.) idluliselwa kwi-OPUS output.

Ingaba ukuguqulwa kwe-AC3 ukuya kwi-OPUS kunokuphinda kuphindeke?

Ungaguqula i-OPUS kwakhona kwi-AC3 kule ndawo. Ukuba nayiphi na ifomati ebandakanyiweyo ilahlekile, i-round-trip ayizukuba yi-bit-perfect nakuba ibonakalayo okanye icacile.

Yintoni umgangatho wemveliso endingalindele ukuba ndiyilindele ukusuka kwi-AC3 ukuya kwi-OPUS?

Izicwangciso ezimiselweyo zijolise kwi-broadcast / umgangatho we-web - ngokubonakalayo ifana nomcebo kubabukeli abaninzi. Ukusetyenziswa kovimba, khetha ukhetho oluphezulu lomgangatho kwimimiselo yoguquli.

Ingaba ukutshintsha AC3 ukuya OPUS kukwindawo yesibini yokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i OPUS encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu impumelelo ihlala icacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i OPUS ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. AC-3 yisandi esilahlekileyo esingenasiqhagamshelanisi esininzi, sihlala siyi-5.1 kwi-384 okanye 448 kbps, nemetadata yonxibelelwano oluqhelekileyo noluphantsi koxinzelelo. Opus ilinganisela ukusuka kwi 6 kbps mono ukuthetha ukuya kwi 510 kbps stereo iingoma kwi bitstream efanayo kwaye itshintshe iimo ngokuzenzekelayo.

Ndingayiphawula i OPUS ngeenkcukacha zomculi ne-albhamu?

Ewe, kwaye yinzuzo elungileyo ngaphezulu kwe AC3, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. OPUS ithatha igama, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. I-Opus yi-codec elungileyo edlalayo elahlekile kwi-bitrates ephantsi ngomda ocacileyo, kwaye inamandla amaphetshana elizwi le-WhatsApp, iDiscord ne-WebRTC.

Yintoni na i-OPUS ifayili?

Isiqulathi seefayili esinomsindo ngaphakathi kwayo, kunokuba umsindo ngokwawo. Lo maleko ongaphezulu yindawo apho ubude, isalathisi sokukhangela kunye ne metadata yefomati echazayo igcinwa khona, ngoko umdlali uyazi ukuba i OPUS ihlala ixesha elingakanani phambi kokucoda iframe enye endaweni yokukhangela ifayile yonke ukufumanisa. Oku kuthetha ukuba unikezelo alusoloko lugqiba into engaphakathi: iziqulathi zeefayili ezininzi ezinjalo zivunyelwe ukuba zigcine ngaphezulu kwesinye isifo sesandi, oko kukuthi, iifayile ezimbini OPUS zingaziphatha ngokuhlukileyo ngelixa zijonge ngaphaya.

Ingaba i OPUS iyadlala kwimoto yam okanye kwizixhobo ezidala?

Ininzi ingxaki. AC3 ikhowudiwe yiyo yonke into, kubandakanya imoto yeqela lenjongo ethile kunye nabadlali abadala; OPUS ifuna udweliso lwenkqubo oluzi ikhowudi, eyona hardware ekhululekileyo ihlala ingakho. Ukuba indawo efanelekileyo yimoto ye stereo okanye umdlali ophathekayo, oku kuyinyani enamandla yokuhlala kwi AC3. I-Opus ayixhaswa yihardware ekhululekileyo - qiniseka ukuba udlala isoftware kuphela, kwaye ulindele ukuba i-car stereos ayihoyi.

Ingaba kukho ilayisensi edityaniswe ne AC3?

Akukho nto ofuna ukuyicinga. I-codec iquka i-patent pools, kwaye ilayisensi ibekwe ngumthumeli we-decoder - ifowuni, umkhangeli zincwadi, inkqubo yokusebenza - ixesha elide phambi kokuba ifayile ifike kuwe. Yiyo loo nto ifomati ikho kuyo yonke indawo kwihardware, kwaye kutheni i royalty- free alternatives yakhiwa naphi na. Ayitshintshanga nto malunga nokutshintsha ifayile oyinayo, kwaye kumbuzo ophilayo kuphela ukuba uthumeli i-encoder ngokwakho.

Ingaba OPUS itsha kakhulu kwizinto endifuna ukuzidlala?

Le yingozi ebonakalayo enye. OPUS yi codec ekutshanje kwaye ingcono kunezinye ezidala kwi bitrate efanayo - iphawuleka ngaphantsi kwe 96 kbps - kodwa "engcono" ayixhaswanga, kwaye iyunithi yemoto, umdlali ohlala ekhululekileyo okanye itelevisi evela phambi kokuba ikhona ayizukuyazi ifayile. Iibrawuzeri, iifowuni kunye neekhompyutha zilungile. Khangela isixhobo esidala esifuna ukuyidlala kwaye ukhethe kuyo, hayi kumanani.

Ingaba kukho umda wobungakanani befayili xa uguqula i-AC3 ibe yi-OPUS?

Ulayisho phezulu olungaziwayo luphelelwe lixesha ngokumiselweyo; i-akhawunti ebhalisiweyo ekhululekileyo ifumana umda ophezulu, kwaye i-akhawunti ye-Pro ayinalo umda wefayili nganye. Inkumbulo yesikhangeli sihlala siyimfuneko yothintelo ixesha elide phambi kokuba umda wethu we-server-side uqale.

Ndingaguqula iifayili ezininzi ze-AC3 zibe yi-OPUS ngaxeshanye?

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze AC3 kwifayili enye yokulayisha - umguquli uqhubekeka nazo ngokuthe tye kwaye ubuyisele i-ZIP yeziphumo ze OPUS. Akukho mfuneko yokuphinda uqhubekeke inkqubo yefayili nganye.
