WebM → 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-WebM imiselwe ukuba incinci: i-VP8 okanye i-VP9 ividiyo (i-AV1 ngoku isasazeka) ene-Vorbis okanye i-Opus isandi, akukho nto enye. 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 WebM, 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. WebM 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 WebM. I-OGG inenkxaso ephantsi yezixhobo zekhompyutha — ii-stereo zemoto, ii-iPods ezidala kunye neeTV ezininzi azibonisi ifayile nanini na.

Ixabiso le-bit elimiselweyo le-lossy OGG yi-192 kbps, ebonisa ngaphaya iingoma. Ungayicima i-320 kbps (audiophile) okanye i-96-128 kbps (ulizwi / ipodcast / ifayili encinci). Ixabiso le-bit eliphantsi livela kukhetho oluphambili phambi kokuba ucofe uguqule.

Ukuba OGG ayilahleki (WAV, FLAC), yonke isampuli igcinwa ngokuchanekileyo. Ukuba OGG ilahlekile (MP3, AAC, OGG, Opus), i OGG codec iphinde icinezele umbhalo ovela kumbhalo - kwi-192 kbps isiphumo sicacile kuzo zonke izinto eziqukayo. Ukuya olungalahleki → olungalahleki akuyi kubuyisela inkcukacha esele zilahlekile.

Ngokungagqibekanga ewe — 48 kHz yesandi kwi WebM yakho ihlala 48 kHz kwi OGG imveliso. Ukukhupha i-CD okanye ukulungelelanisa umdlali ovela kwixesha elidlulileyo ungakhupha isampuli ukuya kwi-44.1 kHz ngesampula-yexabiso eliphantsi; isampuli ephindaphindwayo iphezulu kwi-SoX-grade.

Ewe - shiya isiqulathi seefayili se WebM iifayili kwaye sikhuphe umsindo ngokuthe tye. Abasebenzisi abaphezulu bafumana abasebenza ngokuthe tye abaninzi; kwifayile ye-50 iqela lento le yinto eyahlukileyo phakathi kwemizuzu emibini kunye nemizuzu elishumi elinesibini.

Ukuba i WebM ithatha isithuba okanye i-metadata yokuhamba, sikopa isihloko / umculi / i-albham yemihlaba kwi OGG isiqwenga. Ukuba akunjalo, i OGG iza ngaphandle ingaphawulwanga - sebenzisa umhleli wephetshana elichazayo (Mp3tag, Picard) emva korhwebo ngaphandle lophawulo oluninzi.

I-audio demux + encoding ikhawuleza - iqhelekileyo 5 ukuya kwi 15% yobude bomthombo. I 1- iyure WebM → OGG igqiba kwi 3 ukuya kwi 9 imizuzwana kwindlela eqhelekileyo yokuhambisa; Uthelekiso oluphezulu lukhupha oku ngaphezulu kwimisebenzi yeqela.

Ayikho kule sixhobo ngokuthe ngqo — khupha isandi esipheleleyo njenge OGG, emva koko sebenzisa /audio-trim/ okanye /audio-cutter/ ukucima icandelo. Umendo wenyathelo elinye uhlala ukhawuleza kunenkqubo edityanisweyo kwaye unika ulawulo oluchanekileyo lwe-waveform-level.

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngalinye: abaqeshi ababekwe ngokukodwa, akukho kuhlaziyo lomuntu, ukucinywa okuzenzekelayo ngaphakathi kwemizuzu yokuphela. Ifestile yokugcina epheleleyo ikwi /privacy/.
