AMR Isiguquli

Guqula AMR ukuya nokubuya kwiifomathi ezahlukeneyo

Malunga AMR

I-AMR (I-Adaptive Multi-Rate) yifomathi yocinezelo lwe-audio elungiselelwe ikhowudi yentetho. Iqhele ukusetyenziswa kwiifowuni eziphathwayo ukwenzela ukurekhoda kwelizwi kunye nokudlala kwakhona.

AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni i-AMR yefayili yesandi?

I-AMR yi-codec yokuthetha ethe nkqo-ethe nkqo esetyenziswa kuqala ziinethiwekhi ze-2G/3G ezihambayo. I-AMR ithatha ulizwi eliqondakaliyo kwi-bitrates ephantsi kakhulu kwaye liqhelekileyo kwi-voicemail exports, push-to-talk recordings, ne-old feature-phone voice memos. I-AMR isenza ukuba urekhodo lwesandi lube luncinci kakhulu - iyure enye yokuthetha ilungele ii-megabytes ezimbalwa - kwaye yiyo loo nto ifowuni ezininzi zihlala zirekhoda kuyo uqhagamshelwano.

Ingaba umgangatho sele ulahlekile kwifayili AMR?

Into na leyo ikhowudi yokuqala yagqiba ukuyisusa, ayikwazi ukubuyiselwa. AMR icindezela ngokuyila into ethe indlebe ayizukuyiqaphela - iingoma ezimdaka ezihlala phantsi kwezi zikhulu, ukuphindaphinda kumazantsi okuva - kwaye isuse ngokusisigxina. Kwi bitrate elungileyo engazivakalayo kuninzi lwaba bonke. Into eyiyo ayitshintshi, ngoko ukuguqula kwifomati engalahleki igcina iimeko zangoku kunokuba ibuyisele ioriginal. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, eyenza imodeli yomsebenzi wokuthetha womntu kunokuba isebenze kwi-audio epheleleyo.

Kutheni le nto urekhodo lwam AMR luziva luncinci xa kuthelekiswa nengoma?

Kuba ayikho injongo yayo ukuhambisa umculo. AMR yi codec yokuthetha ethe nkqo eyenziwe kumanethiwekhi ahambayo, elungelelaniswe ukugcina amagama acacileyo kwi bitrate eqikelelwa kwi kilobits yesiqhelo. Yonke into ngaphandle koluhlu lwelizwi lomntu ilahliwe ngexesha lokuqwalasela. Ukutshintsha kwifomati yoluhlu olupheleleyo igcina ushicilelo lusetyenziswa naphi na, kodwa ayinakudibanisa kwakhona ukuphindaphinda okungazange kusampuliswe. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okungaphezulu kweefrequencies zefowuni, kwaye akukho xabiso lokucofa kwakhona liyibuyisela.

Iifayile AMR zivela phi?

Iinkqubo zeposi yelizwi, i-radios ezitsala-ukuthetha, i-handset edala kunye noshicilelo loqhagamshelwano - naphi na apho umsindo wayehamba ngaphezulu kwendlela encinci, ebiza kakhulu. Eli lifa lichaza ukuba kutheni iifayile zincinci kwaye kutheni zithetha ngendlela abayenzayo. Ukuguqula kwenza ukuba zidlale kwisoftware eqhelekileyo; ayikwazi, kwaye ayikwazi, ukongeza ukuthembeka okucaphukisiweyo. I-AMR yi-Adaptive Multi-Rate, i-codec yokuthetha ye-3GPP emiselwe kwi-GSM yezingxoxo zelizwi kunye nezixhobo zokurekhoda ilizwi elihambayo.

Kutheni le nto ifayili yam AMR ivela ngaphandle kwegama lengoma okanye ubugcisa?

Kuba ifomati ayikho naphi na ukugcina. AMR yacaciswa ngaphaya kwesandi sayo, ngaphandle kwendawo eqhelekileyo yesihloko, i-albham okanye umfanekiso wesiqulathi seefayili, ngoko abadlali babuyela umva ukuboniswa kwegama lefayili. Ukutshintsha kwifomati ephawulweyo kwenza ithala leencwadi likwazi ukutyelela - ii-tags zibhalwe ngexesha lokuguqula, kunokuba zibuyiselwe, ngoko lindele ukugcwalisa nantoni na eyamkelwa ngumbhali.

Ingaba ndimele ndigcine iifayile ezintsha njenge AMR?

Ukuba into ephantsi kwendlela ifuna oku. Ifomati iyaqhubeka ivula, kwaye akukho mcimbi wokuguqula uvimba ongazibangela iingxaki, kodwa ayikwazi ukuqhubeka apho isixhobo okanye usebenziso luya khona. Kwanoma iyiphi into entsha, ifomati yangoku ayihlawuli nto engaphezulu kwaye ikhusela umjikelo olandelayo wombuzo kwiminyaka emininzi ezayo.

Kutheni i-AMR ifayili ayidlalwanga kwi-browser yam?

Iibrawuzeri zikhupha ikhowudi kuluhlu olufutshane, oluqinileyo lweefomati zesandi kwaye AMR ingaphandle kwayo, ngoko ifayile ikhupha ezantsi endaweni yokudlala okanye umdlali uxela impazamo. Isoftware yedesktop ene codec ebanzi ivula ngaphandle kwengxaki. Ukuba isandi kufuneka idlala kwiphepha le web, ukuguqula kuyilungisa - akukho mdlali wokumiselwa kwenkqubo uza kudibanisa ikhowudi ekhupha ikhowudi ibrawuzeri ayithuthi.

Yintoni i-bitrate ekufuneka ndiyiguqule iifayile zam AMR?

Uthelekiso lwendawo ebekwe kuyo, hayi umthombo. Kwingoma, 256 ukuya 320 kbps icacile kuye wonke umntu ofundayo; kwilizwi kunye nepodcasts, 96 ukuya 128 kbps ininzi kwaye iqulethe ifayile kwakhona. Ukunxulumana ngaphezulu komthombo we bitrate kusezantsi isithuba - igcina ngokunyanisekileyo isandi esisele sidlula kwindlela elahlekile kwaye ayibuyiseli nto ikhowudi yokuqala elahlekile.

Ingaba i-AMR ilahlekile okanye ayilahleki?

I-AMR ilahlekile - i-encoder isusa i-data i-encoder igqiba ukuba ayithethi ukuba ifike kubungakanani befayili encinci.

Yintoni endingayenza ukuba ndiguqule i-AMR ukuba ndiyisebenzise?

Ukuthumela i-imeyili kunye nokwabelana ngemithombo yeendaba, guqula i-AMR ibe yi-MP3 — ukudlala okubanzi kunye nobungakanani befayili encinci. Ukwabelana ngokuthembekileyo kunye nabaphulaphuli, guqula ibe yi-FLAC okanye i-WAV ukuze ugcine umgangatho ophambili.
