Opus ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

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

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

Ungaguqula i-AMR 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-AMR?

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 AMR kukwindawo yesibini yokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AMR 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 AMR 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-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, eyenza imodeli yomsebenzi wokuthetha womntu kunokuba isebenze kwi-audio epheleleyo.

Ingaba izihloko zam zengoma kunye nemifanekiso ye-albhamu iya kuqhubeka i OPUS ukuya ku AMR uguqulelo?

Ayiqhelekanga. OPUS ihambisa i-metadata efanelekileyo, kodwa AMR ayinandawo eqhelekileyo yomsebenzi womculi, i-albham, inani lengoma okanye ubugcisa besiqhoboshi, ngoko ke iimpawu zilahliwe endaweni yokulahleka. Gcina i OPUS njengekopi ephawulweyo, okanye uphinde uphawule emva kwesixhobo njenge Mp3tag okanye i MusicBrainz Picard. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okungaphezulu kweefrequencies zefowuni, kwaye akukho xabiso lokucofa kwakhona liyibuyisela.

Yintoni na i-AMR ifayili?

Uqhubo olumnyama lwee-frames zesandi ezikhowudiweyo ngaphandle komgcini ojikelezayo. Le yisizathu sokuba iifayile ezimbini AMR 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.

Ithini into ebangela ukuba i-audio ekwi-multichannel iguqulwe kwi OPUS ukuya kwi AMR?

Ijika ezantsi kwi-stereo, kuba AMR ayinayo indlela esebenzayo ye-multichannel. Ukhuphelo lwe-downmix lusebenzisa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-mandla zixutywe kwinqanaba eliphantsi. Nantoni na exhomekeke kubekwa kwesiqhagamshelanisi esikhethekileyo siphelile xa oko kwenzeka.

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.

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

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-AMR ngaxeshanye?

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

Opus

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