WMV kuya MP3 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani i-audio track kusuka ku-WMV njenge-MP3?

Layisha phezulu ihele WMV futhi umguquli ususa umsindo osuka kwi-WMV, bese uguqula ikhodi ibe yi-MP3. Amafreyimu wevidiyo asuswa — akukho sikhathi sevidiyo sesibili, akukho phutha lomgangatho ngaphandle kokukhishwa kwe-MP3 codec. WMV Windows Media Video, Microsoft ASF-based format kusuka Windows XP isikhathi. MP3 yi MPEG-1 Audio Layer III, eqediwe ngo-1993, futhi ikhona ifomethi yomsindo ekwazi ukuconywa ngokugcwele.

Ingabe ukushintsha WMV kuya ku MP3 kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-MP3 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-MP3 kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele. WMV ithatha Microsoft VC-1 noma WMV3 video nge WMA audio - codecs cishe akukho ngaphandle Windows decodes natively. MP3 ilahlekelwa: imodeli ye psychoacoustic isusa iziqongo ezingezona ezivamile, ezivame ukuba ngu-128 kuya ku-320 kbps.

Ingabe ngiyiphawula i MP3 ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe WMV, engeke ikwazi ukugcinwa kuphi naphi. MP3 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. Akukho lutho olushaya i-MP3 ngokuhambisana - i-car stereos, imishini ye-gym, i-DAPs ne-hardware eneminyaka engu-20 yonke ifunde ngaphandle kwemibuzo.

Yini ekwenzeke kumsindo othile uma uguqula WMV ku MP3?

Ihlolwe phansi ku-stereo, ngoba MP3 ayinayo indlela esebenzayo ye-multichannel. Ukuxuba okuphansi kusetshenziswa izilinganiso ezijwayelekile ukuze umhlangano we-channel ephakathi uhlale ucacile futhi izingqimba zixhunywe ku-level ephansi. Noma yini esekelwe ekubekeni kwe-channel ehlukile idlule lapho lokhu kwenzeke. I-MP3 ihlukaniswe ngokukhethekile yi-AAC ne-Opus nganoma yisiphi isivinini se-bit, ingagcina ngaphezulu kwama-channels amabili ngokunembile, futhi ihlala ifaka ukulibazisa okuncane kwe-encoder.

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 MP3 lisebenzisa i-bitrate enjani?

Iphutha MP3 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-MP3 angeke alahlekile (WAV, FLAC) agweme ukumiswa kwe-bitrate futhi agcine yonke isampula.

Ingabe ukusuka ku WMV kuya ku MP3 kuzonciphisa ubunjani bomsindo wami?

Uma i MP3 ifomethi ingekho lutho (WAV, FLAC, ALAC), yonke isampula yangempela igcinwa. Uma i MP3 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-MP3 ekhishwayo igcina i-WMV isilinganiso sesampula?

Ngokungagqibekanga yebo — 48 kHz WMV umsindo ushintsha ube 48 kHz MP3 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 MP3) isampula-rate dropdown yenza lokhu ngekhwalithi ephezulu yokusatshalaliswa kabusha.

Ingabe ngingakwazi ukukhishwa kwe MP3 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 MP3 kusuka ku-WMV wehora elilodwa?

Umsindo demux + transcode usebenza ngokushesha kakhulu kunakhodi yevidiyo - ngokuvamile 5-15% yesikhathi somthombo. Ihora le-1 WMV -> MP3 liphele ngemizuzu engu-3-9 ku-pipeline ejwayelekile. Uma i-MP3 codec ifana ne-source codec esekwi-WMV (ejwayelekile ye-AAC ngaphakathi kwe-MKV / MP4), iyi-remux ecacile futhi isebenza ngemizuzu.

Ingabe ihele MP3 lifaka isihloko / umculi / amathegi we-albhamu?

Uma ihele WMV ligcina i-stream metadata (umculi, isihloko, i-album), sikopa lezi zindawo kuMP3 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 MP3 — sebenzisa i-Mp3tag noma i-Picard emva-kwe-ukukhishwa ukuze uthuthukise.

WMV

I-WMV (I-Windows Media Video) ifomethi yokucindezela ividiyo eyakhiwe yi-Microsoft. Ivame ukusetshenziselwa ukusakaza kanye nezinsizakalo zevidiyo eziku-inthanethi.

MP3

Amafayela e-MP3 asebenzisa ukucindezela okulahlekile ukunciphisa usayizi wefayela ngenkathi kugcinwa ikhwalithi yomsindo eyamukelekayo kubalaleli abaningi.
