MKV ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-audio kwifayili yam MKV njenge AMR?

Layisha phezulu ifayili MKV kwaye umguquli ukhupha umsinga wesandi, emva koko uguqula ukukhowuda ku AMR. Akukho sibini sevidiyo esidlulayo - umkhondo obonakalayo ulahliwe ngokukhawuleza ngoko ke ukutywina kukhawuleza kakhulu kune-re-encoding epheleleyo. MKV yi Matroska, isiqulathi esivuliweyo esidweliswe ngowe-2002 ngaphandle kokungasebenzisi ilayisensi okanye uthintelo oluphezulu olunokunqumla. I-AMR yi-Adaptive Multi-Rate, i-codec yokuthetha ye-3GPP emiselwe kwi-GSM yezingxoxo zelizwi kunye nezixhobo zokurekhoda ilizwi elihambayo.

Ingaba ukutshintsha MKV ukuya ku AMR kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AMR 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 AMR ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-MKV ayisebenzisi i-codec: H.264, HEVC, VP9 ne-AV1 ividiyo ihlala ikhululekile ecaleni kwe-AAC, FLAC, Opus, DTS okanye i-Dolby audio kwifayili enye. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, imodelisa umjelo wokuthetha womntu kunokuba iqulethe i-audio spectrum.

Ithini into ebangela ukuba i-multichannel yesandi iguqulwe kwi MKV ukuya kwi AMR?

Ijika ezantsi kwi-stereo, kuba AMR ayinayo indlela esebenzayo ye-multichannel. Ukudibanisa ezantsi kusetyenziswa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-ndawo zidityanisiwe kwinqanaba eliphantsi. Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo iphela xa oku kwenzeka. I-AMR ibulala umculo: ububanzi besantya sayo esiyi-8 kHz bususa konke okungaphezulu kwesantya sefowuni, kwaye akukho xabiso lokucofa kwakhona olungayibuyisela.

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 kwaye ilahlekile nantoni na enezixhobo kuyo. Ukutshintsha kude nayo akuyi kubuyisela uxinzelelo olulahlekileyo - akufuneki kubekho ukuvulwa kwindawo yokuqala. I-MKV ayinaso nasiphi na isibonelelo sehardware esisemthethweni - iifowuni, iziphene kunye neeTV zihlala zifuna i-VLC okanye i-remux phambi kokuba zidlale.

I-AMR ekhutshiweyo isebenzisa i-bitrate yesandi eyiphi?

Ixabiso le-bit elimiselweyo le-lossy AMR 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.

Ingaba ndiya kulahlekelwa umgangatho wesandi xa ndisuka kwi MKV ukuya kwi AMR?

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

Ingaba i-AMR yesandi igcina umyinge wesikhokelo ongaphambili?

Ngokungagqibekanga ewe — 48 kHz yesandi kwi MKV yakho ihlala 48 kHz kwi AMR 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.

Ndingayikhupha isandi ukusuka kwiifayili ezininzi MKV ukuya kwi AMR kwiqela elinye?

Ewe - shiya isiqulathi seefayili se MKV 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.

Ingaba i AMR izakuphawulwa ngesihloko / umculi / i-metadata ye-albham?

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

Ithatha ixesha elingakanani ukutsala i-AMR yesandi ukusuka kwi-1-iyure i-MKV?

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

Ndingayikhupha icala le-MKV lesandi njenge-AMR?

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

Ingaba ifayili yam MKV ifihlakele ngexesha lokukhupha isandi?

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