Opus ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

It re-encodes a OPUS audio file as AAC. 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-AAC output.

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

Ungaguqula i-AAC kwakhona kwi-OPUS 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-OPUS ukuya kwi-AAC?

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

Ingaba ukutshintsha OPUS ukuya AAC kukwindawo yesibini yokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AAC 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 AAC ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. Opus ilinganisela ukusuka kwi 6 kbps mono ukuthetha ukuya kwi 510 kbps stereo iingoma kwi bitstream efanayo kwaye itshintshe iimo ngokuzenzekelayo. I-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba ifakwe ibhotile kuyilo lwestereo.

Yintoni na i-AAC ifayili?

Uqhubo olumnyama lwee-frames zesandi ezikhowudiweyo ngaphandle komgcini ojikelezayo. Le yisizathu sokuba iifayile ezimbini AAC zingadityaniswa ngokulula ngokubeka enye emva kwenye, kwaye ngokufanayo kutheni konke okungaphezulu kwesandi - ubude, ukukhangela isalathisi, ubugcisa bokuqubha - kufuneka kuboshwe njenge konvensi kunokuba ibe yinxalenye yefomati, ngoko umdlali kufuneka ufunde ifayile yonke usebenze ukuba ide kangakanani. Kumalunga nento elula ebizwa ngokuba yifayile yesandi, eyiyo isizathu sokuba ivela ngaphakathi kwezinye iziqulathi-zifayili rhoqo kuneyo.

Iifayile OPUS zivela phi?

Kwi web, kwaye uninzi lwesoftware kunokuba kwi hardware. OPUS yakhiwa ukudlulisa kunye nezixhobo zendlela evulekileyo, ngoko ivela kwimidlalo yemali, ushicilelo lomkhangeli zincwadi, ipodcast pipelines nantoni na eyenziwe ngabantu abangafunanga unxibelelwano lwelayisensi. Into engabonakalanga kubathengi be-electronic, eyiyo isizathu esiqhelekileyo sokuba umntu kufuneka aguqule enye. I-Opus yi-IETF eqhelekileyo ukusukela ngo-2012 edibanisa i-Skype's SILK speech codec ne-Xiph's CELT music codec kwi-design enye.

Ingaba OPUS ikhululekile ukuyisebenzisa nokusasaza?

Ewe, ngaphandle kweemeko ezifanele ukukhathazeka ngazo. Ukhankaso luza kufumaneka, wonke umntu angasebenzisa ikhowudi okanye ikhowudi esuka kwikhowudi ngaphandle kokubuza okanye ukuhlawula, kwaye akukho mntu unokuguqula ezi zinto emva - nto leyo eyenza ukuba ivele kwi open- source tooling, kwi engines yemidlalo naphi na apho ilayisensi yokuxoxa ibulala iprojekthi. Ukutshintsha kude nayo akuyi kubuyisela oko; iifayile ozinayo zihlala zisetyenziswa ngokuchanekileyo njengoko zazi.

Ubani ochaza AAC?

Ilungu eliqhelekileyo leqela lenkampani, elininzi lesizathu sokuba likho kuyo yonke indawo. AAC yacaciswa ngenkqubo yehlabathi eyenza i-MPEG eqhelekileyo, ngoko abasasazi, abavelisi befowuni, abathengisi besikhangeli kunye nenkonzo yosasazo zonke zazisa uxwebhu olufanayo endaweni yokunika ilayisensi iimveliso zabanye. Isizathu esisebenzayo sibuhlungu kwaye siluncedo: i AAC eyenziwe ngesixhobo esinye ikhupha ikhowudi ngokufanayo kwinye, kwaye akukho mthengisi oxhaswa ngazo ezinokuthi zibuyiselwe. I-AAC yiNkqubo yoKhuseleko lwesandi esiPhambili, emiselwe ngo-1997 njenge-MPEG-2 Inxalenye ye-7 kwaye icwangciswe ngokucacileyo ukubuyisela i-MP3.

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

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-OPUS zibe yi-AAC ngaxeshanye?

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

Ithini into eyenza ukuba i-OPUS yam ifile iguqulwe?

Iifayili ezilayishwe phezulu kunye ne-AAC iimveliso zicinywa ngokuzenzekelayo emva kwefestile efutshane yokugcina. Asiyi kujonga, sizonwabele, okanye siqeqeshe kwiifayili zomsebenzisi. Ikhonkco lokulayisha ezantsi ngokuthe ngqo limiselwe ixesha kwaye lidityaniswe kwintlanganiso yakho.

Opus

Opus yi-codec yesandi evulekileyo eyaziwayo ebetha i-MP3 ne-AAC kwi-bitrates ephantsi, ngenxa yoko unxibelelwano lwelizwi kunye nokudlulisa kusetyenziswa.
