AMR → OGG

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 isiphumo sihlala sicacile 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.

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe AMR, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. OGG ithatha isihloko, 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.

Ihlala ingasebenzi. AMR ikhowudiwe yiyo yonke into, kubandakanya iyunithi yemoto yomlomo kunye nabadlali abadala; OGG ifuna isoftware eyaziyo i-codec, eyona hardware ihlala ingekho. Ukuba indawo efanelekileyo yimoto yestereo okanye umdlali ophathekayo, oku kukholelwa kakhulu ukuba uhlala kwi AMR. I-OGG inenkxaso ephantsi yezixhobo zekhompyutha — ii-stereo zemoto, ii-iPods ezidala kunye neeTV ezininzi azibonisi ifayile nanini na.

Kuba enye icala liyi codec yokuthetha kune codec yengoma. Imodelisa umjelo wokuthetha womntu kwaye ishiya konke ngaphandle kwe bandwidth yefowuni, elungileyo kwimemo yokuthetha kwaye ilahlekile 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.

Ukuba AMR ilahlekile kwaye OGG ayilahleki (umzekelo MP3 → WAV), i OGG ayingcono kune AMR — awunakubuyisela ulwazi olusele lulahlekile. Ukuba AMR ayilahleki kwaye OGG ilahlekile, i OGG codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kumxholo omkhulu.

Iifayile ezininzi kumsebenzi omnye zifuna inkqubo ehlawulweyo. Ukusetyenziswa okukhululekileyo yifayile enye ngoguqulelo, uguqulelo olunye ngeyure. Kwinkqubo ehlawulweyo ungadibanisa iifayile ezininzi kumsebenzi omnye, emva koko ulayishe impumelelo nganye kwiyo okanye zonke kwi ZIP enye.

Ngokungagqibekanga ewe — 48 kHz AMR ihlala i-48 kHz kwi OGG. Ukuba ufuna ukunyusa isampuli ukuze ihambelane (96 kHz → 44.1 kHz yokushicilela i-CD), ukhetho lwesampuli-yexabiso lisebenzisa ukuphinda uthathe isampuli esezingeni eliphezulu kwindlela efanayo yokugqitha kwekhowudi.

Ayiluphi olu hlobo lwendlela. Umguquli awunakucwangcisa ubukhulu besandi kwaye ushiya umphakamo njengonjalo. Ukulinganisa umphakamo, qhuba i OGG egqityiweyo ngesixhobo Sokugqiba esikwindawo.

MP3 idlala phantse naphi na. I-AAC idlala kwizixhobo ze-Apple, ezininzi iifowuni ze-Android kunye ne-Sonos. I-FLAC idlala kwi-Sonos ne-Android kodwa ayiyikubakho kwi-iPods ezidala, kwaye i-WAV idlala phantse nantoni na kodwa iyenza iifayile ezinkulu. Akukho zixhobo ezimiselweyo ezingaphambili kule phepha, ngoko khetha ifomati emiselweyo yomdlali wakho oxhasayo.
