WAV ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni eyenza i-WAV ukuya kwi-AMR iguquli sesandi?

WAV yisandi engalahlekiyo; AMR ilahlekile. Umguquli uphinde ubhale ikhowudi ye-waveform kwi-bitrate emiselweyo. Isiphumo sincinci kakhulu kodwa sisusa ezinye iziqulatho zesantya esingalunganga - ngokuqhelekileyo zicacile kwi-192 kbps+.

Yintoni i-bitrate endingakhetha kuyo i-AMR?

320 kbps yomgangatho wovimba, 256 kbps yokufunda ngokucacileyo kwisandi esikhulu, 192 kbps yokusasaza, 128 kbps xa ubungakanani befayile bulawula. Ngaphantsi kwe 96 kbps iindidi zezinto zibonakala kwizinto eziqulethe i-percussive.

Ingaba ukuguqulwa kwe-WAV ukuya kwi-AMR kunokuphinda kuphindeke?

Ungaguqula i-AMR kwakhona kwi-WAV kule ndawo. Ukuba nayiphi na ifomati ebandakanyiweyo ilahlekile, i-round-trip ayizukuba yi-bit-perfect nakuba ibonakalayo okanye icacile.

Ingaba iAMR iya kuba ncinci kangakanani na kune-WAV yam?

Ngokuqhelekileyo 5-10x ngaphantsi kwemifanekiso, 5-15x ngaphantsi kwesandi. Uthelekiso oluchanekileyo luxhomekeke kumphakamo womgangatho okhethiweyo kunye nento equlethe - imifanekiso ethe tyaba-emnyama nesandi esitshixiweyo sicinezela kakhulu kunemifanekiso ethe nkcukacha okanye iingoma zesandi ezixakekileyo.

Ingaba ndilahlekelwe yintoni ngokuguqula WAV ukuya ku AMR?

Ezinye, kwaye zihlala zikhona - le yindawo enye apho ulwazi luza kuthuthwa khona. WAV igcina yonke imilinganiselo ngokuchanekileyo; AMR isusa into eyenza ukuba imodeli yepsychoacoustic ilindele ukuba awuzukuyiva. Kwi-192 kbps nangaphezulu, le mbono ilungile ngokwaneleyo ukuba icacile kwizinto ezininzi kunye neezixhobo ezininzi. Gcina i WAV njengenkosi yakho, kuba awunakubuyela kuyo ukusuka kwi AMR. I-WAV igcina i-PCM engacinezelwanga emnyama - yonke isampuli igcinwa ngokuchanekileyo, nakweyiphi na ubunzulu be-bit kunye nesantya sesampuli esithathwe. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, eyenza imodeli yomsebenzi wokuthetha womntu kunokuba isebenze kwi-audio epheleleyo.

Yintoni na i-AMR ifayili?

Uqhubo olumnyama lwee-frames zesandi ezikhowudiweyo ngaphandle komgcini ojikelezayo. Le yisizathu sokuba iifayile ezimbini AMR zingadityaniswa ngokulula ngokubeka enye emva kwenye, kwaye ngokufanayo kutheni konke okungaphezulu kwesandi - ubude, ukukhangela isalathisi, ubugcisa bokuqubha - kufuneka kuboshwe njenge konvensi kunokuba ibe yinxalenye yefomati, ngoko umdlali kufuneka ufunde ifayile yonke usebenze ukuba ide kangakanani. Kumalunga nento elula ebizwa ngokuba yifayile yesandi, eyiyo isizathu sokuba ivela ngaphakathi kwezinye iziqulathi-zifayili rhoqo kuneyo.

Ithini into ebangela ukuba i-audio ekwi-multichannel iguqulwe kwi WAV ukuya kwi AMR?

Ijika ezantsi kwi-stereo, kuba AMR ayinayo indlela esebenzayo ye-multichannel. Ukhuphelo lwe-downmix lusebenzisa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-mandla zixutywe kwinqanaba eliphantsi. Nantoni na exhomekeke kubekwa kwesiqhagamshelanisi esikhethekileyo siphelile xa oko kwenzeka. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okungaphezulu kweefrequencies zefowuni, kwaye akukho xabiso lokucofa kwakhona liyibuyisela.

Ingaba WAV ikhululekile ukuyisebenzisa nokusasaza?

Ewe, ngaphandle kweemeko ezifanele ukukhathazeka ngazo. Ukhankaso luza kufumaneka, wonke umntu angasebenzisa ikhowudi okanye ikhowudi esuka kwikhowudi ngaphandle kokubuza okanye ukuhlawula, kwaye akukho mntu unokuguqula ezi zinto emva - nto leyo eyenza ukuba ivele kwi open- source tooling, kwi engines yemidlalo naphi na apho ilayisensi yokuxoxa ibulala iprojekthi. Ukutshintsha kude nayo akuyi kubuyisela oko; iifayile ozinayo zihlala zisetyenziswa ngokuchanekileyo njengoko zazi.

Kutheni umculo uthetha ntoni xa uguqulwa?

Kuba enye icala liyi codec yokuthetha kune codec yengoma. Imodelisa umjelo wokuthetha womntu kwaye ishiya konke ngaphandle kwe bandwidth yefowuni, elungileyo kwimemo yokuthetha neyophazamisayo nantoni na enezixhobo kuyo. Ukutshintsha kude nayo akuyi kubuyisela uxinzelelo olulahlekileyo - akufuneki kubekho ukuvulwa kwindawo yokuqala. I-WAV inamandla amakhulu - malunga ne-10 MB ngemizuzu ye-stereo kwi CD elungileyo - kwaye i-classic format ine-4 GB ye-ceiling kwaye akukho ndawo ye tags efanelekileyo.

Kutheni umntu angaguqula kwi AMR?

Kwinxalenye enye ekhankanyiweyo yenkqubo yekhompyutha okanye ihardware engayi kuthatha nantoni na enye - eyiyo imeko eyanelekayo nesizathu esilungileyo kuphela. AMR ibhekisa kuhlobo oludlulileyo: ii codecs ezintsha zenza umsebenzi ofanayo kubungakanani obuncinane, abadlali abaqhelekileyo- abafunayo bashiya inkxaso yayo endaweni yokudibanisa, kwaye akukho nto entsha iyenziwe ngaphaya kwayo. Ukuba kukho into kumbhobho ofunayo, guqula kwaye ugcine okuqala njengo mlawuli. Ukuba akukho nto iyenzayo, guqula kude kuyo endaweni.

Ingaba kukho umda wobungakanani befayili xa uguqula i-WAV ibe yi-AMR?

Ulayisho phezulu olungaziwayo luphelelwe lixesha ngokumiselweyo; i-akhawunti ebhalisiweyo ekhululekileyo ifumana umda ophezulu, kwaye i-akhawunti ye-Pro ayinalo umda wefayili nganye. Inkumbulo yesikhangeli sihlala siyimfuneko yothintelo ixesha elide phambi kokuba umda wethu we-server-side uqale.

Ndingaguqula iifayili ezininzi ze-WAV zibe yi-AMR ngaxeshanye?

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze WAV kwifayili enye yokulayisha - umguquli uqhubekeka nazo ngokuthe tye kwaye ubuyisele i-ZIP yeziphumo ze AMR. Akukho mfuneko yokuphinda uqhubekeke inkqubo yefayili nganye.
