AC3 ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

It re-encodes a AC3 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-AC3 ukuya kwi-AAC kunokuphinda kuphindeke?

Ungaguqula i-AAC 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-AAC?

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 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. AC-3 yisandi esilahlekileyo esingenasiqhagamshelanisi esininzi, sihlala siyi-5.1 kwi-384 okanye 448 kbps, nemetadata yonxibelelwano oluqhelekileyo noluphantsi koxinzelelo. I-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba ifakwe ibhotile kuyilo lwestereo.

Ndingayiphawula i AAC ngeenkcukacha zomculi ne-albhamu?

Ewe, kwaye yinzuzo elungileyo ngaphezulu kwe AC3, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. AAC ithatha igama, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. I-AAC ithetha ngokucacileyo ngakumbi kune-MP3 engaphantsi kwe-128 kbps kwaye yindawo emiselweyo yokulandela umkhondo wesandi kwi-MP4, YouTube, Apple Music kunye nokusasazwa.

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.

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.

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-AC3 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-AC3 zibe yi-AAC ngaxeshanye?

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze AC3 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-AC3 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.
