WMV ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani kuphela i-audio track ukusuka kwi WMV njenge AAC?

Layisha phezulu ifayili WMV kwaye umguquli ukhupha umsinga wesandi ukusuka kwisiqulathi seefayili WMV, emva koko uguqula ikhowudi ibe yi AAC. Ii-frames zevidiyo zilahliwe — akukho xesha lesibini lokudlulisa ividiyo, akukho lahlekelwa komgangatho ngaphezulu kwento ekhoyo kwi-AAC codec. WMV yiWindows Media Video, iMicrosoft's ASF-based format ukusuka kwixesha leWindows XP. I-AAC yiNkqubo yoKhuseleko lwesandi esiPhambili, emiselwe ngo-1997 njenge-MPEG-2 Inxalenye ye-7 kwaye icwangciswe ngokucacileyo ukubuyisela i-MP3.

Ingaba ukutshintsha WMV ukuya ku AAC kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AAC 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 AAC 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-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba iboniswe kwi-stereo design.

Ndingayiphawula i AAC ngeenkcukacha zomculi ne-albham?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe WMV, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. AAC ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. I-AAC ithetha ngokucacileyo ngakumbi kune-MP3 engaphantsi kwe-128 kbps kwaye yindawo emiselweyo yokulandela umkhondo wesandi kwi-MP4, YouTube, Apple Music kunye nokusasazwa.

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.

Ingoma yesandi eyiphi ephumayo xa WMV yam iqulethe ezininzi?

Ngokungagqibekanga umsinga 0 (umkhondo wokuqala wesandi, ngokuqhelekileyo umxube omkhulu). Ukuba i-WMV yakho ithatha iinkcazelo, i-dubs, okanye i-audio echazayo kwiimvavanyo ezongezelelweyo, umkhethi ophambili "umsinga wesandi" ukuvumela ukuba ukhethe 1, 2, 3... ngokucacileyo. Uluhlu lwemikhondo luboniswe kwimboniso yokukhuphela ukuze ungakhetha ngokuzifihla.

I-AAC ifayili isebenzisa i-bitrate enjani?

I-AAC emiselweyo ye-bitrate yi-192 kbps (ibonisa ngaphaya kwengoma kwiimvakalelo ezininzi). Nciphisa kwi-320 kbps yemveliso yeaudiophile, okanye 96-128 kbps yelizwi/ipodcast apho ifayili encinci iphambili. Iinjongo ezingalahlekiyo AAC (WAV, FLAC) zingahoyi isicwangciso se-bitrate kwaye zigcine zonke iiseti.

Ingaba ukutshintsha ukusuka ku WMV ukuya ku AAC kuya kunyusa ubunjani besandi sam?

Ukuba i AAC ifomati ayilahleki (WAV, FLAC, ALAC), yonke isampuli ebhaliweyo igcinwa. Ukuba i AAC ilahlekile (MP3, AAC, OGG, Opus), i-codec iphinda icinezele - kwi-192 kbps utshintsho aluthethiweyo kwizinto ezininzi; kwi-96 kbps ungava i-cymbals okanye i-sibilants ecocekileyo. I-WMV isiqwengana asiyi kubangela oku - i-codec kuphela emiselweyo ebalulekileyo.

Ingaba i-AAC ekhutshweyo igcina i-WMV inqanaba lesampuli?

Ngokungagqibekanga ewe — 48 kHz WMV isandi siyi 48 kHz AAC isandi, 44.1 kHz siyi 44.1 kHz. Ukuba ufuna ukunyusa isampuli ukuhambelana (umzekelo. 96 kHz studio masters ukuya 44.1 kHz CD-quality AAC) isampuli-rate dropdown yenza oku ngesampuli ephezulu-yexabiso.

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

I-audio demux + transcode iqhuba ngokukhawuleza kunevidiyo yokubuyisela kwikhowudi - ihlala i-5-15% yobude bomthombo. Iyure ye-1 WMV -> AAC igqiba kwimizuzu ye-3-9 kwindlela eqhelekileyo yokuhambisa. Ukuba i-AAC codec ifana ne-source codec sele kwi-WMV (eqhelekileyo kwi-AAC ngaphakathi MKV / MP4), yi-remux ecocekileyo kwaye iqhuba kwimizuzu.
