Guqula WMA kuya FLAC

Ngephutha yebo — i-stereo ihlala i-stereo, isilinganiso sesampula sakuqala (44.1 kHz, 48 kHz, njll.) sithunyelwe ku-FLAC output.

Yebo — umsindo ongenawo umonakalo uvame ukuba 5-10x omkhulu kunawo umsindo ongenawo umonakalo ngekhwalithi elinganayo. Phinda ubeke isinqumo se ~10 MB ngomzuzu FLAC versus ~1 MB ngomzuzu we-high-bitrate WMA.

Yebo — izihlungi ezingalahleki zigcina wonke ama-byte. Lindela ukuthi i-FLAC ibe ngu-3-8x ubukhulu be-WMA. Inani elingcono lizoba ukuthi akukho ukulahleka kwekhwalithi engaphezulu ekuhlelani noma ekuphindeni ukungenisa.

Akuna, futhi kufanelekile ukuba kucace: akukho okuzokwenzeka. I WMA 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 kokulungisa, 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. WMA ayixhaswanga cishe kuwo wonke indawo ngaphandle Windows, futhi WMA older amafayela angaba nesi DRM ukuthi ivala ukuguqulwa ngokuphelele.

Ibhokisi lemisindo ngaphakathi kwalo, hhayi i-audio ngokwayo. Lo mbhalo ongeziwe uhlala lapho ubude, umbiko wokufuna kanye nanoma yimiphi imininingwane ye-metadata ifomu lichaza khona, ngakho umdlali ungazi ukuthi i FLAC ihlala isikhathi esingakanani ngaphambi kokuqothula ifremu eyodwa endaweni yokuskena ihele lonke ukuze ufunde. Lokhu kusho futhi ukuthi ubukhulu abukwazi ukuxazulula okungaphakathi: amabhokisi amaningi anjalo avunyelwe ukuphatha okungaphezu kwehlobo elinye lomsindo, ngakho amafayela amabili FLAC angasebenza ngendlela ehlukile ngenkathi ebona ngokufana ngaphandle. I-FLAC isebenzisa ukubikezela okuqondile kanye nokuhlelwa kwe-Rice ukufinyelela cishe ku-50-60% wesayizi yangempela ngesikhathi sokuhlelwa emuva kwe-PCM efana ne-bit.

Kulokhu kuphela ukuthi ukukopela kudlulele. WMA okuqokwa kusuka ku-diski kwacindezelwa nganoma yisiphi isivinini se-bit esibekwe yi-ripper eminyakeni edlule, futhi lokho kuyi-top of the list kunoma yini esuka phansi - ukushintshana akukwazi ukubuyisela lokho okuqokwa kukhuphuke. Uma ama-diski akhona ethekwini, ukushintshana kabusha kufomethi engalahleki nokukopela kusuka lapho kunikeza imiphumela engcono kunanoma iyiphi i-conversion yefayela elikhona. WMA Windows Media Audio, Microsoft's impendulo MP3, yaqala ngo-1999 futhi bundled ngazo zonke Windows ukufaka lesikhathi.

DRM. Iqoqo elincane lamafayela WMA 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.

Akuna omunye ongacabanga ngawo. I-codec ifakwe iziqukathi zepatenti, futhi ilayisense ibekwe ngumuntu othumela umbhalo oguquliwe — ifoni, i-browser, i-operating system — isikhathi eside ngaphambi kokuba ifayela lifike kuwe. Lokhu kusho ukuthi ifomu likhona kuwo wonke amahardware, futhi kungani izinketho ezingenazo i-royalty zikhiwa. Akunalutho olushintshayo mayelana nokushintsha ifayela olizithola, futhi kuyimibuzo ephilayo uma uthumela umbhalo oguquliwe wena.

Ukuthunyelwa okungaziwa kuvunyelwe ngokuzenzakalela; ama-akhawunti abhalisiwe amahhala athola umkhawulo ophezulu, futhi ama-akhawunti we-Pro angeke abe ne-limit yefayela ngalinye. Umlando wesiphequluli uvame ukuba ngumkhawulo osebenzayo ngaphambi kokuba umkhawulo wethu we-server-side uqale.

Yebo. Thola noma khetha amafayela amaningi we-WMA ku-upload eyodwa — umguquli usebenza ngazo ngokufanayo futhi ubuyisela i-ZIP yemiphumela ye-FLAC. Akunasidingo sokuphinda isikhashana sokufaka ihele ngalinye.

Amafayela alayishiwe kanye ne-FLAC outputs zisuswa ngokuzenzakalela ngemuva kwefasitela lokugcinwa okuncane. Asihlolanga, asihlukanisi, noma siqeqeshe amafayela womsebenzisi. Ama-download links aqondile angaphansi kwesikhathi esilinganiselwe futhi axhunywe kwinhlanganiso yakho.
