WMV ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-audio kwifayili yam WMV njenge MP3?

Layisha phezulu ifayili WMV kwaye umguquli ukhupha umsinga wesandi, emva koko uguqula ukukhowuda ku MP3. Akukho sibini sevidiyo esidlulayo - umkhondo obonakalayo ulahliwe ngokukhawuleza ngoko ke ukutywina kukhawuleza kakhulu kune-re-encoding epheleleyo. WMV yiWindows Media Video, iMicrosoft's ASF-based format ukusuka kwixesha leWindows XP. I-MP3 yi-MPEG-1 Umphezulu Wosandi III, egqityiwe ngo-1993, kwaye ihlala i-format yesandi ekwazi ukucoda ngokupheleleyo ekhoyo.

Ingaba ukutshintsha WMV ukuya ku MP3 kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i MP3 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 MP3 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-WMV ihambisa i-Microsoft VC-1 okanye i-WMV3 yevidiyo ngesandi se-WMA — ii-codecs azikho nto ngaphandle kweWindows ikhupha ikhowudi ngokusemthethweni. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Ndingayiphawula i MP3 ngeenkcukacha zomculi ne-albham?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe WMV, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. MP3 ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. Akukho nto ibetha iMP3 ekusebenzeni kwayo - iistereo zemoto, izixhobo zegym, iiDAPs kunye nezixhobo zekhompyutha ezineminyaka engama-20 ubudala zonke zifunda ngaphandle kwemibuzo.

Ithini into ebangela ukuba i-multichannel yesandi iguqulwe kwi WMV ukuya kwi MP3?

Ijika ezantsi kwi-stereo, kuba MP3 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. MP3 igqityiwe nge AAC ne Opus kwinqanaba ngalinye le-bitrate, ayikwazi ukugcina ngaphezulu kweendawo ezimbini eziluncedo, kwaye ihlala idibanisa ulibaziso oluncinci lwe-encoder.

Kutheni ezinye zeefayili zam WMV azitshintshi?

DRM. Iqela elincinci le WMV iifayile zifihliweyo yindawo yokurhweba okanye isoftware ekhupheleyo, kwaye umsindo ofihliweyo awunakucinywa uphawu nganoma uphi umguquli. Nantoni na oyiyikhuphe ngokwakho, uyirekhode, okanye uyithengise ngaphandle kokhuselo iguqula ngokuqhelekileyo; ukuthengiswa kwelayisensi akuyi kwenza njalo. WMV isebenza kakuhle iphele elahlekile: macOS, iOS, Android kunye ne-browser nganye kufuneka i-decoders yeqela lesithathu, kwaye ezinye iifayile ze-WMV zithwala i-DRM engatshintshi nantoni na.

I-MP3 ekhutshiweyo isebenzisa i-bitrate yesandi eyiphi?

Ixabiso le-bit elimiselweyo le-lossy MP3 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 WMV ukuya kwi MP3?

Ukuba MP3 ayilahleki (WAV, FLAC), yonke isampuli igcinwa ngokuchanekileyo. Ukuba MP3 ilahlekile (MP3, AAC, OGG, Opus), i MP3 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-MP3 yesandi igcina umyinge wesikhokelo ongaphambili?

Ngokungagqibekanga ewe — 48 kHz yesandi kwi WMV yakho ihlala 48 kHz kwi MP3 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 WMV ukuya kwi MP3 kwiqela elinye?

Ewe - shiya isiqulathi seefayili se WMV 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 MP3 izakuphawulwa ngesihloko / umculi / i-metadata ye-albham?

Ukuba i WMV ithatha isithuba okanye i-metadata yokuhamba, sikopa isihloko / umculi / i-albham yemihlaba kwi MP3 isiqwenga. Ukuba akunjalo, i MP3 iza ngaphandle ingaphawulwanga - sebenzisa umhleli wephetshana elichazayo (Mp3tag, Picard) emva korhwebo ngaphandle lophawulo oluninzi.

Ithatha ixesha elingakanani ukutsala i-MP3 yesandi ukusuka kwi-1-iyure i-WMV?

I-audio demux + encoding ikhawuleza - iqhelekileyo 5 ukuya kwi 15% yobude bomthombo. I 1- iyure WMV → MP3 igqiba kwi 3 ukuya kwi 9 imizuzwana kwindlela eqhelekileyo yokuhambisa; Uthelekiso oluphezulu lukhupha oku ngaphezulu kwimisebenzi yeqela.

Ndingayikhupha icala le-WMV lesandi njenge-MP3?

Ayikho kule sixhobo ngokuthe ngqo — khupha isandi esipheleleyo njenge MP3, emva koko sebenzisa /audio-trim/ okanye /audio-cutter/ ukucima icandelo. Umendo wenyathelo elinye uhlala ukhawuleza kunenkqubo edityanisweyo kwaye unika ulawulo oluchanekileyo lwe-waveform-level.

WMV

WMV yividiyo yeMicrosoft evela kwixesha le Windows Media, i compact kwixesha layo kodwa i awkward nakweyiphi na into ngaphandle kwe Windows.

MP3

Iifayile zeMP3 zisebenzisa ucinezelo olulahlekileyo ukunciphisa ubungakanani befayile ngelixa zigcina umgangatho wesandi owamkelekileyo kubaphulaphuli abaninzi.
