Indlela yokuguqula MP4 ukuba AMR

Inyathelo 1: Rhweba ngaphakathi MP4 iifayili usebenzisa iqhosha phezulu okanye nge shift nendawo.

Inyathelo 2: Nqakraza kwiqhosha 'Uguqulo' ukuqala uguqulo.

Inyathelo 3: Gcina ifayile yakho eguqulweyo AMR iifayile

MP4 ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-audio kwifayili ye-MP4 njenge-AMR?

Layisha phezulu ifayili ye-MP4 kwaye siyikhuphe i-demux irekhodi lesandi, emva koko siyiguqule ibe yi-AMR. Akukho xesha lesibini lokudlulisa ividiyo kwaye akukho lahlekelwa komgangatho ngaphandle kwe-AMR codec ngokwayo.

I-AMR isebenzisa i-bitrate yesandi eyiphi?

I-AMR bitrate emiselweyo yi-192 kbps (ibonisa ngaphaya kwengoma). Ungayicima i-320 kbps (i-audiophile) okanye i-96-128 kbps (ilizwi / ipodcast / ifayili encinci). Ukhetho luvela kwiinketho eziphambili.

Ingaba ndiya kulahlekelwa umgangatho wesandi xa ndisuka kwi-MP4 ukuya kwi-AMR?

Ukuba i-AMR ifomati ayilahli (WAV, FLAC), ugcina isampuli nganye ngokuchanekileyo. Ukuba i-AMR ilahlekile (MP3, AAC, OGG), i-AMR codec iphinda icinezele — umgangatho uxhomekeke kwi-bitrate kunye nombhalo wesandi. Simiselwe kwi-192 kbps ebonisa ngaphaya kwanoma iyiphi imixholo.

Ingaba i-AMR ekhutshweyo igcina umyinge wesikhokelo sayo sakuqala?

Ngokungagqibekanga ewe — i-48 kHz yesandi esuka kwi-MP4 ivela kwi-48 kHz kwi-AMR. Ukuba ufuna i-44.1 kHz (umgangatho we-CD) ukuhambelana nabadlali abadala, iinketho eziphambili ziquka i-sample-rate dropdown.

Ndingayikhupha isandi kwiifayili ezininzi ze MP4 ukuya kwi AMR kwiqela elinye?

Ewe — shiya isiqulathi seefayili ze MP4 ngaphakathi kwaye sikhuphe isandi ngokuthe tye. Abasebenzisi abaphezulu bafumana abasebenzi abathe tye abaninzi; kwifayili ye-50-batch le yinto eyahlukileyo phakathi kweemizuzu ezili-90 nemizuzu eli-8.

Ingaba ifayili ye AMR izakuphawulwa ngesihloko / umculi / i-albham?

Ukuba i-MP4 ifaka isahluko okanye i-metadata yokuhamba, sikopa umculi / isihloko / imihlaba ye-albham kwi-AMR isiqwenga. Kungenjalo i-AMR ifayile ayiphawulwanga — sebenzisa umhleli we-tag (Mp3tag, Picard) emva korhwebo ngaphandle ukuba ufuna i-tags eninzi.

Ithatha ixesha elingakanani ukutsala i-AMR ukusuka kwifayili ye-MP4?

Ukutsala isandi kukhawulezayo kakhulu kunokuphinda kubhalwe ikhowudi ividiyo - ihlala ithatha i-5-15% yobude bomthombo. Iyure enye MP4 → AMR igqiba kwimizuzu emi-3-9 kwinkqubo eqhelekileyo.

Ndingayikhupha icala le-MP4 yesandi njenge-AMR?

Akukho kule sixhobo - khupha isandi esipheleleyo njenge AMR apha, emva koko sebenzisa /audio-trim/ okanye /audio-cutter/ ukucima icandelo. Umendo wenyathelo elinye uhlala ukhawuleza kunenkqubo edityanisiweyo.

Ingaba ifayili yam MP4 ifihlakeleyo ngexesha lokukhupha isandi?

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngasinye: abasebenzi ababekwe ngokuzimeleyo, ukucinywa okuzenzekelayo kwimizuzu, akukho hlaziyo lomxholo. Bona /privacy/.

Kutheni ifayili yam AMR isebenzisa izithuba ezingasebenziyo?

Iindawo ezizitshixo zithetha ukuba ifayili ye-MP4 iqulethe ubeko lwesandi oluninzi lweengoma kwaye sikhethe umsinga ongafanelekanga. Sebenzisa ukhetho oluphambili "umsinga wesandi" ukukhetha ngokucacileyo umsinga 0, 1, njl.njl., okanye uphinde uhlanganise zonke iziqhagamshelanisi kwi-AMR yesiqulathi seefayili esininzi se-AMR ukuba i-AMR ixhasa oku.

Ingaba ukususwa kwe-AMR ku stereo / mono / 5.1?

Ubeko lwesiqhagamshelanisi lugcinwa ukusuka kwi-MP4 ngokumiselweyo — i-5.1 MP4 ivelisa i-5.1 AMR apho i-codec ixhasa khona (AAC, FLAC, OGG). Unganyanzelisa i-stereo okanye i-mono nge-channel-downmix option, esetyenziswa kwi-podcast workflow.

Ingaba i-AMR ekhutshweyo iyadlala kwi-iPhone / Android / i-car stereo?

I-MP3 idlala naphi na. I-AAC / M4A idlala kwi-Apple neninzi ye-Android. I-OGG / Opus ifuna umdlali okutsha kwi-iOS. Iinketho eziphambili zibonisa "isixhobo" esimiselweyo esikhetha i-AMR codec enokuthi idlala kwinjongo yakho.
