WebM ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili WebM kwaye umguquli ukhupha umsinga wesandi ukusuka kwisiqulathi seefayili WebM, 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. I-WebM yinxalenye encinci eqinileyo ye-Matroska epapashwe yiGoogle ngo-2010 ekhethekileyo ukunika i-HTML5 ividiyo isiqulathi seefayili esingenazo iirhafu. I-AAC yiNkqubo yoKhuseleko lwesandi esiPhambili, emiselwe ngo-1997 njenge-MPEG-2 Inxalenye ye-7 kwaye icwangciswe ngokucacileyo ukubuyisela i-MP3.

Ingaba ukutshintsha WebM 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-WebM imiselwe ukuba incinci: i-VP8 okanye i-VP9 ividiyo (i-AV1 ngoku isasazeka) ene-Vorbis okanye i-Opus isandi, akukho nto enye. 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 WebM, 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.

Ingoma yesandi eyiphi ephumayo xa WebM yam iqulethe ezininzi?

Ngokungagqibekanga umsinga 0 (umkhondo wokuqala wesandi, ngokuqhelekileyo umxube omkhulu). Ukuba i-WebM 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 WebM 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-WebM isiqwengana asiyi kubangela oku - i-codec kuphela emiselweyo ebalulekileyo.

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

Ngokungagqibekanga ewe — 48 kHz WebM 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.

Ndingazikhuphela njani ii-AAC zesandi kwisiqulathi seefayili se-WebM?

Ewe — susa isiqulathi seefayili WebM kwindawo yokulayisha kwaye siqhube ukususwa ngokuthe tye. I-Premium ifumana abasebenzi abathe tye abaninzi; kwi-100-file batch (uluhlu lwemiculo-ividiyo) le yi-difference phakathi kweemizuzu ezi-90 nemizuzu eli-8.

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

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

Ingaba ifayili AAC izakuthwala isihloko / umculi / i-tag ye-albham?

Ukuba i-WebM ifayili igcina i-metadata yokuhamba (umculi, isihloko, i-albham), sikopa ezi ndawo kwi AAC isiqulathi seefayili apho ifomati ixhasa ii-tags. ID3v2 (MP3), i-Vorbis iphawula (OGG, FLAC), i-MP4 i-atoms (AAC / M4A), RIFF INFO (WAV) zonke zibhalwe. I-Untagged WebM ivelisa i-untagged AAC — sebenzisa i- Mp3tag okanye i-Picard emva-korhwebo ngaphandle ukunika amandla.

Ingaba i WebM yam ifihlakeleyo xa ndisusa umsindo?

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngalinye. Umsuka WebM nemveliso AAC ziqhubekekiswa kubasebenzi abakhuselekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala, sigcine, okanye sisebenzise imixholo. Bona /privacy/.

Kutheni i AAC yam isebenzisa izithuba ezizinyamalalayo okanye isebenzisa isandi esingalunganga?

I-WebM yakho iqulethe ubeko lwesandi se-multi-track kwaye sakhupha umsinga ongachanekanga (umzekelo, umsinga wesandi ochazayo okhululekileyo endaweni yoxubo oluphambili). Phinda uqhube nge "umsinga wesandi" ophambili okhethwayo omiselwe kwisikhombisi esifanelekileyo, okanye ukhethe "zonke iziqhagamshelanisi" ukukhupha umsinga ngamnye njengefayili ehlukileyo ye AAC.
