AMR ukuba OGG Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

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

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

Ungaguqula i-OGG kwakhona kwi-AMR 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-AMR ukuya kwi-OGG?

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

Ingaba ukutshintsha AMR ukuya OGG kukwindawo yesibini yokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i OGG 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 OGG ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, eyenza imodeli yomsebenzi wokuthetha womntu kunokuba isebenze kwi-audio epheleleyo. I-Vorbis ngaphakathi kwe-OGG ilahlekile kwaye isebenzisa i-bitrate etshintshayo ngokumiselweyo, ngoko umgangatho umiselwe njengomgangatho kunokuba ubungakanani obuthe nkqo be-kbps.

Ndingayiphawula i OGG ngeenkcukacha zomculi ne-albhamu?

Ewe, kwaye yinzuzo elungileyo ngaphezulu kwe AMR, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. OGG ithatha igama, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. I-OGG Vorbis ibetha i-MP3 kwi-bitrate elinganayo kwaye ihambisa akukho xabiso lelayisensi, nto leyo eyenza ukuba i-enjini yomdlalo kunye nesoftware evulekileyo ithathele ingqalelo i-elektroniki.

Yintoni na i-OGG 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 OGG 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 OGG zingaziphatha ngokuhlukileyo ngelixa zijonge ngaphaya.

Ingaba i OGG iyadlala kwimoto yam okanye kwizixhobo ezidala?

Ininzi ingxaki. AMR ikhowudiwe yiyo yonke into, kubandakanya imoto yeqela lenjongo ethile kunye nabadlali abadala; OGG ifuna udweliso lwenkqubo oluzi ikhowudi, eyona hardware ekhululekileyo ihlala ingakho. Ukuba indawo efanelekileyo yimoto ye stereo okanye umdlali ophathekayo, oku kuyinyani enamandla yokuhlala kwi AMR. I-OGG inenkxaso ephantsi yezixhobo zekhompyutha — ii-stereo zemoto, ii-iPods ezidala kunye neeTV ezininzi azibonisi ifayile nanini na.

Ingaba kukho ilayisensi edityaniswe ne AMR?

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.

Kutheni umculo uthetha ntoni xa uguqulwa?

Kuba enye icala liyi codec yokuthetha kune codec yengoma. Imodelisa umjelo wokuthetha womntu kwaye ishiya konke ngaphandle kwe bandwidth yefowuni, elungileyo kwimemo yokuthetha neyophazamisayo nantoni na enezixhobo kuyo. Ukutshintsha kude nayo akuyi kubuyisela uxinzelelo olulahlekileyo - akufuneki kubekho ukuvulwa kwindawo yokuqala. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okungaphezulu kweefrequencies zefowuni, kwaye akukho xabiso lokucofa kwakhona liyibuyisela.

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

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-AMR zibe yi-OGG ngaxeshanye?

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