WebM kuya WMA Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani i-audio track kusuka ku-WebM njenge-WMA?

Layisha phezulu ihele WebM futhi umguquli ususa umsindo osuka kwi-WebM, bese uguqula ikhodi ibe yi-WMA. Amafreyimu wevidiyo asuswa — akukho sikhathi sevidiyo sesibili, akukho phutha lomgangatho ngaphandle kokukhishwa kwe-WMA codec. I-WebM iyingxenye eqinile ye-Matroska eshicilelwe yi-Google ngo-2010 ekhethekile ekubeni yividiyo ye-HTML5 equkethwe ngaphandle kwe-royalty. WMA Windows Media Audio, Microsoft's impendulo MP3, yaqala ngo-1999 futhi bundled ngazo zonke Windows ukufaka lesikhathi.

Ingabe ukushintsha WebM kuya ku WMA kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-WMA 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-WMA kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele. WebM idinga ukucophelela: VP8 noma VP9 ividiyo (AV1 manje) nge Vorbis noma Opus umsindo, futhi akukho okuthile okuningi. I-WMA ilahlekelwa yiphutha, ebhokisini le-ASF, nge-lossless nezwi elingcono kakhulu elivame ukutholakala.

Ingabe ngiyiphawula i WMA ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe WebM, engeke ikwazi ukugcinwa kuphi naphi. WMA 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-WMA icindezelwe kahle kunalokho okusho ama-MP3 encoders amanje futhi ihlala ifundeka yi-Windows Media Player nezinhlelo zakudala ze-PlaysForSure.

Ingabe i-WMA izodlala emoto yami noma ku-hardware edala?

Ngokuvamile akunjalo. WebM i-decoded yinoma yini, kufaka phakathi izimoto eziphezulu nezidlali ezikhulu; WMA idinga isofthiwe eyazi i-codec, esizohlala i-hardware ehlala ikhona. Uma indawo esiya kuyo imoto ye-stereo noma umdlali ophathekayo, lokhu kuyisinqumo esiqinile sokuhlala ku WebM. WMA ayixhaswanga cishe kuwo wonke indawo ngaphandle Windows, futhi WMA older amafayela angaba nesi DRM ukuthi ivala ukuguqulwa ngokuphelele.

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

Ngephutha umsindo 0 (umsindo wokuqala, ngokuvamile umsindo omkhulu). Uma WebM 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 WMA lisebenzisa i-bitrate enjani?

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

Ingabe ukusuka ku WebM kuya ku WMA kuzonciphisa ubunjani bomsindo wami?

Uma i WMA ifomethi ingekho lutho (WAV, FLAC, ALAC), yonke isampula yangempela igcinwa. Uma i WMA 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-WebM i Container ayinaso isikhundla kulolu hlelo — ukumiswa kwe-codec kuphela okubalulekile.

Ingabe i-WMA ekhishwayo igcina i-WebM isilinganiso sesampula?

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

Ingabe ngingakwazi ukukhishwa kwe WMA umsindo kusuka kusibaya sehele WebM?

Yebo — susa isibaya se WebM 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 WMA kusuka ku-WebM wehora elilodwa?

Uma i-WMA codec ifana ne-source codec esekwi-WebM (ejwayelekile ye-AAC ngaphakathi kwe-MKV / MP4), iyi-remux ecacile futhi isebenza ngemizuzu.

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

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

Ingabe WebM yami imfihlo ngesikhathi sokukhipha umsindo?

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