WMV → FLAC

Akunalutho, futhi kufanelekile ukuba kucace: akukho okuzokwenzeka. I WMV idlulele i-detail ngesikhathi sokuqothula kwayo okujwayelekile, futhi ukubopha okushiwo ku FLAC ongeke ulahlekelwa yilutho kugcina lokho - akukho okuningi. Ihele lithola izikhathi eziningi ezikhulu futhi lizwakala lifana. Kukhona ukunyakaza okulungile ngaphambi kokuhlela, ngoba FLAC ngeke ihlanganise isizukulwane sesithathu sezinto ezibonakalayo uma ukhipha. I-FLAC ikunikeza ukuthembeka kwe-WAV kungxenyekazi yesayizi, nge-metadata efanele kanye ne-artwork efakwe, ngakho-ke ilawula ama-library omculo angeke alahlekelwa. 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.

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe WMV, engeke ikwazi ukugcinwa kuphi naphi. FLAC 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.

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.

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.

Iphutha FLAC 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-FLAC angeke alahlekile (WAV, FLAC) agweme ukumiswa kwe-bitrate futhi agcine yonke isampula. I-FLAC isebenzisa ukubikezela okuqondile kanye nokuhlelwa kwe-Rice ukufinyelela cishe ku-50-60% wesayizi yangempela ngesikhathi sokuhlelwa emuva kwe-PCM efana ne-bit.

Uma i FLAC ifomethi ingekho lutho (WAV, FLAC, ALAC), yonke isampula yangempela igcinwa. Uma i FLAC 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.

Ngokungagqibekanga yebo — 48 kHz WMV umsindo ushintsha ube 48 kHz FLAC 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 FLAC) isampula-rate dropdown yenza lokhu ngekhwalithi ephezulu yokusatshalaliswa kabusha.

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.

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

Uma ihele WMV ligcina i-stream metadata (umculi, isihloko, i-album), sikopa lezi zindawo kuFLAC 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 FLAC — sebenzisa i-Mp3tag noma i-Picard emva-kwe-ukukhishwa ukuze uthuthukise.

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