Indlela yokuguqula AC3 kuya AMR

Isinyathelo 1: Layisha eyakho AC3 amafayela usebenzisa inkinobho engenhla noma ngokuhudula bese uphonsa.

Isinyathelo 2: Chofoza inkinobho ethi 'Guqula' ukuze uqale ukuguqulwa.

Isinyathelo 3: Landa i-version yakho AMR amafayela

AC3 kuya AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Ingabe AC3 kuya ku AMR ukuguqulwa kubuyiselwa emuva?

Ungaguqula i-AMR emuva ku-AC3 kule site. Uma ifomethi eyodwa ilahlekile, i-round-trip ayilungile noma ngabe ibukeka noma izwakala ifana.

Yini ikhwalithi yesipiliyoni okufanele ngilinde kusuka ku-AC3 kuya ku-AMR?

Izilungiselelo ezizenzakalelayo zidinga ukusakazwa / ukhwalithi ye-web — ngokubona kufana nomthombo weningi labasebenzisi. Ukusetshenziswa kwegobolondo, khetha ukhetho lwekhwalithi ephezulu kuzinhlelo zokushintsha.

Ingabe ukushintsha AC3 kuya ku AMR kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i AMR encoder isebenza kusuka kumsindo osele udlulele esinye isikhala se-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une master engalahlekelwa yilutho, ukukopisha i AMR kusuka lapho kunciphisa isikhala esimibili ngokuphelele. AC-3 yisandi esingenalutho esingena-channel, sivame u-5.1 ku-384 noma ku-448 kbps, ne-metadata yokuxoxa nokuhlanganiswa ngezansi. I-AMR iyi-narrowband speech codec esebenza phakathi kuka-4.75 no-12.2 kbps, emodela i-human vocal tract endaweni yobubanzi obugcwele be-audio spectrum.

Yini okushoyo ihele AMR?

Ukuhamba okuncane kwefremu yomsindo okhonjiswanga ngaphandle kwebhokisi elijikelezayo. Lokhu kusho ukuthi amafayela amabili AMR angaxhunywa ngokulula ngokubeka elinye ngemuva kwelinye, futhi ngokufanayo kusho ukuthi konke okungaphezu komsindo - ubude, ukufuna isibalo, ukuhoxa umdwebo - kufanele kufakwe ibhodlela njengenhlanganiso ngaphezu kokuyingxenye yefomethi, ngakho umdlali kufanele afunde ihele lonke ukuze asebenze ukuthi lide kangakanani. Kulokhu, into elula kakhulu ebizwa ngokuthi ihele lomsindo, okuwukuthi kungani livela ngaphakathi kwezinye izibhokisi ngaphezu kokuvela ngokwalo.

Ingabe kunelayisense exhunywe ku AC3?

Akuna omunye ongacabanga ngawo. I-codec ifakwe iziqukathi zepatenti, futhi ilayisense ibekwe ngumuntu othumela umbhalo oguquliwe — ifoni, i-browser, i-operating system — isikhathi eside ngaphambi kokuba ifayela lifike kuwe. Lokhu kusho ukuthi ifomu likhona kuwo wonke amahardware, futhi kungani izinketho ezingenazo i-royalty zikhiwa. Akunalutho olushintshayo mayelana nokushintsha ifayela olizithola, futhi kuyimibuzo ephilayo uma uthumela umbhalo oguquliwe wena.

Kungani umculo uzwakala ubuhlungu kulo mguquko?

Ngenxa yokuthi ingxenye eyodwa iyi-codec yokuxoxa hhayi i-codec yomculo. Imodelisa i-human vocal tract futhi isusa konke ngaphandle kwe-bandwidth yefoni, elungile ku-voice memo futhi ebulalayo kunoma yini enezithuluzi ngaphakathi. Ukushintshana eduze kwayo akukwazi ukubuyisela ama-frequencies angekho — angeke abhalwe ngokucophelela endaweni yokuqala. AC-3 ayisebenzi kahle ngokuya ngemigomo yamanje futhi ayivunyelwe yiziphequluli, amafoni noma abadlali abaningi be-web ngaphandle kokuxhuma phezulu kwe-stereo.

Kungani umuntu angaguqula ku AMR?

Kuye kungxenyekazi eyodwa noma ihardware ekhethekile engeke ithathe noma yini enye - okuwumphumela ongokoqobo kanye nesizathu esingcono kuphela. AMR ihlobene nohlobo oludlule: ama-codecs amasha asebenza ngokufanayo kubukhulu obuncane, abadlali abazosebenzisa ngokuvamile bashiya ukuxhaswa kwayo endaweni yokungeza, futhi akukho okusha okuzokwakhiwa kuyo. Uma kukhona okuthile emgodini ofuna okuthile, guqula futhi ugcine okujwayelekile njengomkhulu. Uma akukho okukwenzayo, guqula kude nayo. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okuphezulu kwe-frequency yefoni, futhi akukho inani lokuphindeka kokucofa liyibuyisela emuva.

Ingabe kunesikhawulo sobukhulu befayela uma uguqula i-AC3 ibe yi-AMR?

Ukuguquka okumahhala kunesilinganiselo sobukhulu sehele ngalinye, esisetshenzisiwe ngohlobo lwehele, futhi ikhasi lizokutshela uma ihele lidlula kulo. Iphrojekthi ekhokhelwayo isusa lesi silinganiselo, ngakho amafayela amakhulu angaguqulwa.

Ingabe ngingenza ukuguqulwa kwe-batch kwefayela le-AC3 elilodwa libe yi-AMR?

Amafayela amaningi emisebenzini eyodwa adinga iphrojekthi ekhokhelwa. Ukusetshenziswa okumahhala kuyisifayela esisodwa ngasinye sokuguqulwa, ukuguqulwa okufanayo ngehora. Kuphrojekthi ekhokhelwa ungangeza amafayela amaningi kumsebenzi owodwa, bese ulanda impendulo ngayinye yayo noma zonke ku-ZIP eyodwa.

Yini ezoba namafayela ami AC3 ngemuva kokuguqulwa?

Amafayela alayishwe phezulu aphathwa kumaseva ethu okuguqula, akukho muntu obhekana nawo, futhi ahlukaniswe. Ukufaka kanye nohele oluguqulwe kususwa ngokuzenzakalela cishe amahora angu-24 ngemuva kokuguqulwa, okushiya isikhathi sokulanda imiphumela. Bona /privacy/ ukuphoqa okuphelele.

Yini izinhlelo ezidlala ihele AMR?

AMR idlala emidlalweni emikhulu yomculo, iziphequluli, nama-media library. I-iTunes / Apple Music, VLC, Foobar2000, nama-phone media apps aphatha lokhu ngokusemthethweni.

Ingabe ngidinga ukufaka isofthiwe ukushintsha AC3 ibe AMR?

Akuna. Umguquli usebenza ngokuphelele kwi-browser yakho kanye ne-cloud yethu - akukho plugin, akukho kufaka, akukho malungelo omsebenzisi. Isebenza ku-Windows, macOS, Linux, ChromeOS, iOS, ne-Android.
