AMR Izixhobo

Tshintsha 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-narrow-band speech codec eyaqala isetyenziswa yi-2G/3G mobile networks. I-AMR ithatha ilizwi eliqondakaliyo kwi-bitrates ephantsi kakhulu kwaye iqhelekileyo kwi-voicemail exports, ucinezelo-ukuxoxa urekhodo, kunye ne-feature-phone voice memos edala.

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 ibe yiyo ukuze ndiyisebenzise?

Ukwabelana nge-imeyili kunye nemidiya yoluntu, guqula i-AMR ibe yi-MP3 — ukudlala okubanzi kunye nobungakanani befayili encinci. Ukwabelana ngokuthembekileyo nabalandeli besandi, guqula ibe yi-FLAC okanye i-WAV ukugcina umgangatho ophambili.

Uguqulelo lutshintsha ubungakanani befayili ngaphi?

Ukutshintsha i-AMR ibe yifomati engalahlekiyo njenge-WAV okanye i-FLAC igcina ubungakanani bukhulu; ukutshintsha ibe yi-MP3 okanye i-AAC kwi-bitrates eqhelekileyo (192-320 kbps) ikhupha ifayili nge-5-10x ngento encinci ebonakalayo yotshintsho lomgangatho.

Ingaba i-AMR yam yesandi sokungenelela iyasebenza kwi-iPhone?

Ii-iPhone ringtones kufuneka zibe kwi-M4R format (i-Apple's ringtone container). Guqula i-AMR ibe yi-M4R usebenzisa i-MOV.to, emva koko udlulise i-M4R file kwisixhobo sakho nge-Finder okanye nge-Apple Devices.

Ingaba ifile ye-AMR ihlala ixesha elingakanani phambi kokuba i-MOV.to iyifumane?

Akukho mda wexesha olunzima - i-cap ikwi-file size. Abasebenzisi abakhululekileyo bafumana i-100 MB nganye yokulayisha (iyure okanye ngaphezulu ye-AMR yesandi kwi-bitrates eqhelekileyo). Abasebenzisi abaqeqeshiweyo bafika kwi-GB ezininzi.

Ingaba i-MOV.to igcina i-metadata (iimpawu, umzobo we-albham) ukusuka kwi-AMR?

Ewe — ii-tags ze-ID3, umculi/i-albham/isihloko, kunye nemisebenzi yobugcisa efakwe kwifayili yakho ye-AMR igcinwa kwimveliso apho ifomati yendawo yokusingqongileyo ixhasa khona. I-WAV isusa i-metadata eninzi ngoyilo, ngoko ke ukutshintsha kwi-WAV kuya kususa ii-tags.

Ndingayikhupha isandi kwividiyo njenge-AMR?

Ewe. Layisha phezulu i-MP4, MOV, MKV okanye nayiphi na ividiyo exhaswayo kwaye ukhethe i-AMR njengemveliso. MOV.to ikhupha i-mux yengoma yesandi kwaye iphinde ikhowudi kuphela ukuba ifuneka.

Ingaba i-MOV.to icima iifayile zam ze-AMR emva kokuguqulwa?

Ewe. Ukukhuphela kwakho i-AMR kunye nemveliso eguqulweyo zicinywa ngokuzenzekelayo emva kwefestile efutshane. Asiyi kugcina, siyiva, okanye siyisebenzise isandi sakho.

Yintoni i-bitrate endingakhetha xa ndiguqula ukusuka kwi-AMR?

Umdlalo, 256-320 kbps yindawo emnandi - ecacileyo kubaphulaphuli abaninzi. Ulizwi kunye nepodcasts, 96-128 kbps ininzi. Ukuya phezulu kune-bitrate yombhalo-mbhalo awukwazi ukubuyisela umgangatho wombhalo-mbhalo osele ulahlekile.
