WMV kuya AAC Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani i-audio track kusuka ku-WMV njenge-AAC?

Layisha phezulu ihele WMV futhi umguquli ususa umsindo osuka kwi-WMV, bese uguqula ikhodi ibe yi-AAC. Amafreyimu wevidiyo asuswa — akukho sikhathi sevidiyo sesibili, akukho phutha lomgangatho ngaphandle kokukhishwa kwe-AAC codec. WMV Windows Media Video, Microsoft ASF-based format kusuka Windows XP isikhathi. I-AAC iyi-Advanced Audio Coding, ejwayelekile ngo-1997 njenge-MPEG-2 Part 7 futhi ifakwe ngokucacile ukushintsha i-MP3.

Ingabe ukushintsha WMV kuya ku AAC kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-AAC encoder isebenza kusuka kumsindo osele udlulele engxenyeni eyodwa ye-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, uku-encoding i-AAC kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele. WMV ithatha Microsoft VC-1 noma WMV3 video nge WMA audio - codecs cishe akukho ngaphandle Windows decodes natively. I-AAC ilahlekelwa yizinto kodwa isebenza kahle kunayo i-MP3, futhi iphatha kuze kube yi-48 channels ngokusemthethweni ngaphezu kokuboshwa ku-stereo design.

Ingabe ngiyiphawula i AAC ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe WMV, engeke ikwazi ukugcinwa kuphi naphi. AAC ifaka isihloko, umculi, i-album, unyaka, inani le-track kanye ne-cover art efakwe ngaphakathi kwebhokisi, ngakho-ke i-library yomculo ifaka ngokulungile ngaphandle kokufaka isandla. I-AAC izwakala ingcono kakhulu kune-MP3 ngaphansi kuka-128 kbps futhi iyi-audio track ejwayelekile ku-MP4, YouTube, Apple Music ne-broadcast.

Kungani ezinye ze WMV zefayela lami zingaguqulwa?

DRM. Iqoqo elincane lamafayela WMV libhalwe ngokufihlakele yisitolo noma isofthiwe eyenza, futhi umsindo obhalwe ngokufihlakele awukwazi ukukhishwa yinoma iyiphi i-convertor. Noma yini oyidingayo, orekhodiwe, noma othengiswe ngaphandle kokuvikelwa uguqulwa ngokuvamile; ukuthengiswa kwelayisense akuzokwenza. WMV ngokuphumelelayo iphele efile: macOS, iOS, Android kanye nesipiliyoni ngasinye idinga isithathu-party decoders, futhi ezinye WMV amafayela zithwala DRM ukuthi akufanele kushintshwe ngaso sonke isikhathi.

Yiyiphi i-track yomsindo ekhishwayo uma WMV yami iqukethe eziningi?

Ngephutha umsindo 0 (umsindo wokuqala, ngokuvamile umsindo omkhulu). Uma WMV wakho ufaka umlayezo, ama-dubs, noma umsindo ochazayo kuma-tracks angeziwe, umkhethi othuthukisiwe "umsindo" ukuvumela ukuthi ukhethe 1, 2, 3... ngokucacile. Uhlu lwe-track lubonisa ukufinyelela kokubuka kuqala ukuze ungakhetha ngokuzifihla.

Ihele AAC lisebenzisa i-bitrate enjani?

Iphutha AAC i-bitrate yi-192 kbps (icacile kuma-earphones amaningi). Nciphisa ku-320 kbps nge-audiophile output, noma 96-128 kbps ngezwi/podcast lapho ihele elincane liyisisekelo. Ama-AAC angeke alahlekile (WAV, FLAC) agweme ukumiswa kwe-bitrate futhi agcine yonke isampula.

Ingabe ukusuka ku WMV kuya ku AAC kuzonciphisa ubunjani bomsindo wami?

Uma i AAC ifomethi ingekho lutho (WAV, FLAC, ALAC), yonke isampula yangempela igcinwa. Uma i AAC ingekho lutho (MP3, AAC, OGG, Opus), i-codec icindezela futhi — ku-192 kbps ushintsho alukwazi ukulizwa kuningi kwezithameli; ku-96 kbps ungalizwa ama-cymbals noma ama-sibilans abandayo. I-WMV i Container ayinaso isikhundla kulolu hlelo — ukumiswa kwe-codec kuphela okubalulekile.

Ingabe i-AAC ekhishwayo igcina i-WMV isilinganiso sesampula?

Ngokungagqibekanga yebo — 48 kHz WMV umsindo ushintsha ube 48 kHz AAC umsindo, 44.1 kHz ushintsha ube 44.1 kHz. Uma ufuna ukuncipha kwesampula ukuze kusebenze (isibonelo 96 kHz studio masters kuya ku 44.1 kHz CD-quality AAC) isampula-rate dropdown yenza lokhu ngekhwalithi ephezulu yokusatshalaliswa kabusha.

Ingabe ngingakwazi ukukhishwa kwe AAC umsindo kusuka kusibaya sehele WMV?

Yebo — susa isibaya se WMV amafayela endaweni yokulayisha futhi siqhube ukukhishwa ngokufanayo. I-Premium ithola abasebenzi abafanayo abaningi; ku-100-file batch (uhlelo lwemiculo-video olujwayelekile) lokhu kuyinto ehlukile phakathi kwamasekondi angama-90 namaminithi angama-8.

Ingabe kuthatha isikhathi esingakanani ukukhishwa kwe AAC kusuka ku-WMV wehora elilodwa?

Umsindo demux + transcode usebenza ngokushesha kakhulu kunakhodi yevidiyo - ngokuvamile 5-15% yesikhathi somthombo. Ihora le-1 WMV -> AAC liphele ngemizuzu engu-3-9 ku-pipeline ejwayelekile. Uma i-AAC codec ifana ne-source codec esekwi-WMV (ejwayelekile ye-AAC ngaphakathi kwe-MKV / MP4), iyi-remux ecacile futhi isebenza ngemizuzu.

Ingabe ihele AAC lifaka isihloko / umculi / amathegi we-albhamu?

Uma ihele WMV ligcina i-stream metadata (umculi, isihloko, i-album), sikopa lezi zindawo kuAAC isitoreji lapho ifomu lixhasa amathegi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC / M4A), RIFF INFO (WAV) wonke abhalwe. Ukungabi nathegi WMV kwenza AAC — sebenzisa i-Mp3tag noma i-Picard emva-kwe-ukukhishwa ukuze uthuthukise.

Ingabe WMV yami imfihlo ngesikhathi sokukhipha umsindo?

Yebo — imodeli yobumfihlo efanayo nezo zonke iziguqulo. Umsuka WMV nesokudla AAC zicutshungulwa kubasebenzi abahlukanisiwe futhi zicishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe. Bona /privacy/.
