AMR Amathuluzi

Tshintsha AMR kuya futhi kusuka kumafomethi ahlukahlukene

Mayelana AMR

I-AMR (I-Adaptive Multi-Rate) ifomethi yokuminyanisa yomsindo elungiselelwe ukubhalwa kwekhodi yenkulumo. Ivamise ukusetshenziswa kumakhalekhukhwini ukuqoshwa kwezwi nokudlalwa komsindo.

AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini ihele lomsindo le-AMR?

I-AMR iyi-narrow-band speech codec esetshenziswa kuqala yi-2G/3G mobile networks. I-AMR iqoqa umsindo ocacile nge-bitrates ephansi kakhulu futhi ivame ukutholakala emiyalezo yezwi, ukurekhodwa kwe-push-to-talk, kanye nama-memos omsindo wefoni edala.

Ingabe i-AMR ilahlekelwa noma ayilahlekelwanga?

I-AMR ilahlekelwa — umbhalo-mbhalo ususa idatha umbhalo-mbhalo ucabanga ukuthi ayikwazi ukulinganiswa ukuze ifike kubungakanani befayela elincane.

Yini okufanele ngiguqule i-AMR ibe yiyo ukuze ngiyihlukanise?

Ukuthumela i-imeyili kanye nokuhlukaniswa kwemidiya yomphakathi, guqula i-AMR ibe yi-MP3 — ukusakazwa okuphelele nobukhulu befayela elincane. Ukusabalalisa okuphezulu-nokuzinikela nabangani besandi, guqula ube yi-FLAC noma i-WAV ukuze ugcine ukhwalithi yokuqala.

Ingabe ukuguquka kuzoshintsha ubukhulu behele?

Ukushintsha i-AMR ibe yifomethi engalahleki njenge-WAV noma i-FLAC igcina ubukhulu bukhulu; ukushintsha ibe yi-MP3 noma i-AAC nge-bitrates ejwayelekile (192-320 kbps) icindezela ifayela ngama-5-10x ngeshintsho elincane lomgangatho obonakalayo.

Ingabe umsindo wami we-AMR uzosebenza ku-iPhone?

iPhone izithonjana zocingo kufanele kube M4R ifomu (Apple's ringtone isitoreji). Guqula AMR ukuba M4R usebenzisa MOV.to, bese udlulisa i M4R ifayela kwidivayisi yakho nge Finder noma Apple Izisetshenziswa.

Ingabe ifile ye-AMR ingahlala isikhathi esingakanani ngaphambi kokuba i-MOV.to iyisake?

Akukho sikhathi esinzima sokuphela - i-cap itholakala kubukhulu befayela. Abasebenzisi abamahhala bathola i-100 MB ngayinye yokulayisha (ngokwesibonelo, ihora noma ngaphezulu kwe-AMR audio ku-bitrates ejwayelekile). Abasebenzisi be-Pro bafinyelela ku-GB eminingi.

Ingabe i-MOV.to igcina i-metadata (ithegi, isithombe se-albhamu) kusuka ku-AMR?

Yebo — amathegi we-ID3, umculi/i-albhamu/isihloko, kanye nemisebenzi yezandla efakwe kwifayela lakho le-AMR zigcinwa kwi-output lapho ifomethi yokufinyelela ixhasa khona. I-WAV isusa i-metadata ngokuhlelwa, ngakho ukushintsha i-WAV kuzosusa amathegi.

Ingabe ngizokhipha umsindo kusuka kuvidiyo njenge-AMR?

Yebo. Layisha phezulu i-MP4, MOV, MKV noma iyiphi ividiyo exhaswe bese ukhetha i-AMR njenge-output. MOV.to isusa umsindo futhi iphinde ikhode uma kudingeka.

Ingabe i-MOV.to icima amafayela ami we-AMR ngemuva kokuguqulwa?

Yebo. Ukufaka kwakho i-AMR kanye ne-output eguqulwe isuswa ngokuzenzakalela ngemuva kwefasitela elincane. Asigcinanga, asilalela, noma sihlukanise umsindo wakho.

Yini i-bitrate okufanele ngiyikhethe uma ngiguqula kusuka ku-AMR?

Ku-music, 256-320 kbps yindawo emnandi — ecacile kubantu abaningi abalalelayo. Ku-voice kanye ne-podcasts, 96-128 kbps kuningi. Ukuya phezulu kune-bitrate yomthombo akukwazi ukubuyisela ukhwalithi yomthombo osele ulahlekile.
