Indlela yokuguqula WebM ukuba AMR

Inyathelo 1: Layisha eyakho WebM iifayile usebenzisa iqhosha elingasentla okanye ngokutsala nokuwisa.

Inyathelo lesi-2: Cofa iqhosha elithi 'Guqula' ukuze uqalise ukuguqula.

Inyathelo lesi-3: Khuphela i-converted yakho AMR iifayile

WebM ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-audio kwifayili WebM njenge AMR?

Layisha phezulu ifayili WebM kwaye siyi-demux i-audio track, emva koko siyi-transcode kwi AMR. Akukho sibini sevidiyo esidlulayo kwaye akukho lahlekelwa komgangatho ngaphandle koku kuqala kwe-AMR codec.

I-AMR ifayili isebenzisa i-bitrate yesandi enjani?

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

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

Ukuba AMR ayilahleki (WAV, FLAC), isampuli nganye igcinwa ngokuchanekileyo. Ukuba AMR ilahlekile (MP3, AAC, OGG, Opus), i-AMR codec iphinda icinezele — kwi-192 kbps oku kucacile kuzo zonke iziqulatho. Ukubuyisela ubunjani obusele buhambe kwi-WebM source akuvumelekanga.

Ingaba i-AMR ekhutshweyo igcina i-sample rate yangaphambili?

Ngokungagqibekanga ewe — i-48 kHz yesandi yengoma kwi WebM ivela kwi-48 kHz kwi AMR. Ukuba ufuna i-44.1 kHz (umgangatho we-CD) ukuhambelana nabadlali abadala, iinketho eziphambili zibonisa i-sample-rate dropdown ephinda iphinde isampele ngesihluzi esiphezulu somgangatho.

Ndingayikhupha i-audio kwiifayili ezininzi WebM kwi AMR kwiqela elinye?

Ewe — susa isiqulathi seefayili WebM ngaphakathi kwaye sikhuphe isandi ngokuthe tye. Abasebenzisi abaqeqeshiweyo bafumana abasebenzi abathe tye abaninzi; kwifayili ye-50-iqela lento le yinto eyahlukileyo phakathi kweemizuzu engama-90 nemizuzu engama-8.

Ingaba ifayili AMR iya kuphawulwa ngesihloko / umculi / i-albham?

Ukuba isiqulathi seefayili WebM sinesahluko okanye i-metadata yokuhamba, siyakopa imihlaba yomculi / isihloko / i-albham kwi AMR isiqulathi seefayili apho i-AMR ixhasa i-tags. Kungenjalo i-AMR ifayili ayiphawulwanga — sebenzisa umhleli we-tag (Mp3tag, Picard) emva korhwebo ngaphandle lwee-tags ezininzi.

Ithatha ixesha elingakanani ukushenxisa i-AMR kwifayili ye-WebM?

Ukutsala isandi kukhawulezayo kakhulu kunokuphinda kubhalwe ikhowudi ividiyo - ngokuqhelekileyo 5-15% yobude bomthombo. Iyure ye-1 WebM -> AMR igqiba kwimizuzu ye-3-9 kwinkqubo eqhelekileyo.

Ndingayikhupha icala le-WebM yesandi njenge-AMR?

Akukho kule sixhobo siphela - khupha isandi esipheleleyo njenge AMR apha, emva koko sebenzisa /audio-trim/ okanye /audio-cutter/ ukucima icandelo. Umendo wenyathelo elinye ukhawulezayo kunenkqubo edityanisiweyo kuba sithintela ukubuyisela kwakhona i-decoding yefayili yonke kabini.

Ingaba ifayili yam WebM ifihlakeleyo xa ndikhupha 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 WebM iqulethe ubeko lwesandi oluninzi lweengoma kwaye sikhethe umsinga ongafanelekanga. Sebenzisa ukhetho "umsinga wesandi" ukukhetha ngokucacileyo umsinga 0, 1, njl.njl., okanye uphinde uhlanganise zonke iziqhagamshelanisi kwi-multi-track AMR isiqwenga apho AMR ixhasa khona.

Ingaba ukususwa kwe AMR ku stereo / mono / 5.1?

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

Ingaba i-AMR ekhutshiweyo 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.
