AMR kuya WAV Imibuzo Evame Ukubuzwa Yokuguqulwa

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

AMR sele ilahlekelwa, ngakho ukushintsha ku WAV kugcina umsindo okhona ngaphandle kokuncipha okuningi, kodwa akukwazi ukubuyisela imininingwane elahlekile ekuqondeni okusemthethweni. WAV kulungile uma uhlela ukuhlela futhi ugcine kabusha ngaphandle kokuxubana kwezinto ezibonakalayo zokucindezeleka.

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-WAV output.

Ingabe ihele WAV lizoba likhulu kakhulu kunalo AMR?

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

Ingabe i-WAV ingaphezulu kwe-AMR?

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

Ingabe ukushintsha AMR kuya ku WAV kuthuthukisa ukhwalithi yomsindo?

Akuna, futhi kufanelekile ukuba kucace: akukho okuzokwenzeka. I AMR idlulele i-detail ngesikhathi sokuqothula kwayo okujwayelekile, futhi ukubopha okushiwo ku WAV ongeke ulahlekelwa yilutho kugcina lokho - akukho okuningi. Ihele lithola izikhathi eziningi ezikhulu futhi lizwakala lifana. Kukhona ukunyakaza okulungile ngaphambi kokulungisa, ngoba WAV ngeke ihlanganise isizukulwane sesithathu sezinto ezibonakalayo uma ukhipha. WAV iyifomethi efanele yokuhlela, ukuphatha nokulondoloza, ngoba ingaphinde ikhodwe noma yikuphi inani lamahora ngaphandle kokuqoqa ama-artefacts. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okuphezulu kwe-frequency yefoni, futhi akukho inani lokuphindeka kokucofa liyibuyisela emuva.

Yini okushoyo ihele WAV?

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 WAV 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 WAV angasebenza ngendlela ehlukile ngenkathi ebona ngokufana ngaphandle. WAV igcina ngokuvamile i-PCM engacindezelwanga engaqondakali — yonke isampula igcinwa ngokugcwele, noma yikuphi ububanzi be-bit nesampula yezinga elithathwe.

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.

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

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-WAV?

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

Yini ezoba namafayela ami AMR ngemuva kokuguqulwa?

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

Yini izinhlelo ezidlala ihele WAV?

WAV idlala emidlalweni emikhulu yomculo, iziphequluli, nama-media library. I-iTunes / Apple Music, VLC, Foobar2000, nama-phone media apps aphatha lokhu ngokusemthethweni.
