AMR kuya WMA Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini oyenzayo i-AMR kuya ku-WMA umguquli womsindo?

It re-encodes a AMR audio file as WMA. Sample rate and channel count are preserved; the difference is the codec and container.

Ingabe isilinganiso sesampula kanye nesimo sesixhumi sigcinwa?

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

Ingabe AMR kuya ku WMA ukuguqulwa kubuyiselwa emuva?

Ungaguqula i-WMA emuva ku-AMR kule site. Uma ifomethi eyodwa ilahlekile, i-round-trip ayilungile noma ngabe ibukeka noma izwakala ifana.

Yini ikhwalithi yesipiliyoni okufanele ngilinde kusuka ku-AMR kuya ku-WMA?

Izilungiselelo ezizenzakalelayo zidinga ukusakazwa / ukhwalithi ye-web — ngokubona kufana nomthombo weningi labasebenzisi. Ukusetshenziswa kwegobolondo, khetha ukhetho lwekhwalithi ephezulu kuzinhlelo zokushintsha.

Ingabe ukushintsha AMR 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 esinye isikhala se-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une master engalahlekelwa yilutho, ukukopisha i WMA kusuka lapho kunciphisa isikhala esimibili ngokuphelele. I-AMR iyi-narrowband speech codec esebenza phakathi kuka-4.75 no-12.2 kbps, emodela i-human vocal tract endaweni yobubanzi obugcwele be-audio spectrum. 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 esemthethweni ngaphezulu kwe AMR, engeke ikwazi ukugcinwa kuphi naphi. WMA ifaka isihloko, umculi, i-album, unyaka, inani le-track kanye ne-incrusted cover art kwibhokisi le-container, ngakho-ke i-music library 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.

Yini okushoyo ihele WMA?

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 WMA 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 WMA angasebenza ngendlela ehlukile ngenkathi ebona ngokufana ngaphandle.

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

Ngokuvamile akunjalo. AMR i-decoded yinoma yini, kufaka phakathi iyunithi yemoto kanye nabadlali abadala; WMA idinga isofthiwe eyazi i-codec, esebenzisa ihardware ehlukile. Uma indawo esiya kuyo imoto ye-stereo noma umdlali ophathekayo, lokhu kuyisinqumo esiqinile sokuhlala ku AMR. WMA ayixhaswanga cishe kuwo wonke indawo ngaphandle Windows, futhi WMA older amafayela angaba nesi DRM ukuthi ivala ukuguqulwa ngokuphelele.

Ingabe kunelayisense exhunywe ku AMR?

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.

Kungani umculo uzwakala ubuhlungu kulo mguquko?

Ngenxa yokuthi ingxenye eyodwa iyi-codec yokuxoxa hhayi i-codec yomculo. Imodelisa i-human vocal tract futhi isusa konke ngaphandle kwe-bandwidth yefoni, elungile ku-voice memo futhi ebulalayo kunoma yini enezithuluzi ngaphakathi. Ukushintshana eduze kwayo akukwazi ukubuyisela ama-frequencies angekho — angeke abhalwe ngokucophelela endaweni yokuqala. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okuphezulu kwe-frequency yefoni, futhi akukho inani lokuphindeka kokucofa liyibuyisela emuva.

Ingabe kunesikhawulo sobukhulu befayela uma uguqula i-AMR ibe yi-WMA?

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.

Ingabe ngingenza ukuguqulwa kwe-batch kwefayela le-AMR elilodwa libe yi-WMA?

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