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 yam WebM njenge AMR?

Layisha phezulu ifayili WebM kwaye umguquli ukhupha umsinga wesandi, emva koko uguqula ikhowudi ibe yi AMR. Akukho sibini sevidiyo esidlulayo - irekhodi elibonakalayo lilahliwe ngokuzenzekelayo ngoko ke ukutywina kukhawuleza kakhulu kune-encoding epheleleyo. I-WebM yinxalenye encinci eqinileyo ye-Matroska epapashwe yiGoogle ngo-2010 ekhethekileyo ukunika i-HTML5 ividiyo isiqulathi seefayili esingenazo iirhafu. I-AMR yi-Adaptive Multi-Rate, i-codec yokuthetha ye-3GPP emiselwe kwi-GSM yezingxoxo zelizwi kunye nezixhobo zokurekhoda ilizwi elihambayo.

Ingaba ukutshintsha WebM ukuya ku AMR kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AMR encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i AMR ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-WebM imiselwe ukuba incinci: i-VP8 okanye i-VP9 ividiyo (i-AV1 ngoku isasazeka) ene-Vorbis okanye i-Opus isandi, akukho nto enye. 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 umculo uthetha ntoni xa uguqulwa?

Kuba enye icala liyi codec yokuthetha kune codec yengoma. Imodelisa umjelo wokuthetha womntu kwaye ishiya konke ngaphandle kwe bandwidth yefowuni, elungileyo kwimemo yokuthetha kwaye ilahlekile nantoni na enezixhobo kuyo. Ukutshintsha kude nayo akuyi kubuyisela uxinzelelo olulahlekileyo - akufuneki kubekho ukuvulwa kwindawo yokuqala. I-WebM ilungile naphi na ngaphandle kwebrowser - abahleli bevidiyo, ii-galeri zefowuni eziqhelekileyo kunye neSmart TVs ziyihoyi kakhulu.

I-AMR ekhutshiweyo isebenzisa i-bitrate yesandi ethini?

I-lossy AMR ikhowudiwe kwi-192 kbps ngokumiselweyo. Isicwangciso Somgangatho Wesandi sinika 320 kbps kumgangatho olungileyo kunye ne-128 kbps kwifayili encinci. I-lossless AMR (WAV, FLAC) i ignores the bitrate and keeps every sample.

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 umbhalo wesandi - kwi-192 kbps isiphumo sicacile kuzo zonke iziqulatho. Ukuya kwi-lossy → ayilahleki akuzukubuyisela iinkcukacha ezisele zilahlekile.

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

Iifayile ezininzi kumsebenzi omnye zifuna inkqubo ehlawulweyo. Ukusetyenziswa okukhululekileyo yifayile enye ngoguqulelo, uguqulelo olunye ngeyure. Kwinkqubo ehlawulweyo ungadibanisa iifayile ezininzi kumsebenzi omnye, emva koko ulayishe impumelelo nganye kwiyo okanye zonke kwi ZIP enye.

Ithatha ixesha elingakanani ukutsala i-AMR yesandi ukusuka kwi-WebM yeyure?

Oku kuxhomekeke kubungakanani nobude befayile. Amaxwebhu amancinci kunye nemifanekiso ihlala ilungile ngokukhawuleza. Iividiyo ezide zithatha ixesha elide, kuba iinguqulelo ezininzi zevidiyo ziphinde zikhowudi iframe nganye.

Ndingayikhupha icala le-WebM yesandi njenge-AMR?

Akukho kule sixhobo ngokuthe ngqo — khupha isandi esipheleleyo njenge AMR, emva koko sebenzisa /audio-trim/ okanye /audio-cutter/ ukucima icandelo. Umendo wenyathelo elinye uhlala ukhawuleza kunenkqubo edityanisweyo kwaye ukunika ulawulo oluchanekileyo lwenqanaba le-waveform.

Ingaba ifayili yam WebM ifihlakeleyo ngexesha lokukhupha isandi?

Ewe. Iifayile ezilayishwe phezulu ze WebM ziqhubekekiswa kwiseva yethu yokuguqula, akukho mntu ujonge phezulu, kwaye azisasazwanga. Ukukhuphela kunye nokuguqulwa kwe AMR kususwa ngokuzenzekelayo malunga neyure ezili-24 emva kokuguqulwa, oshiya ixesha lokulayisha ezantsi iziphumo. Bona /privacy/ kwinkqubo epheleleyo.

Kutheni le nto ifayili AMR ineengcambu ezingasebenziyo apho i WebM ikwisandi?

I WebM ihlala ithatha ngaphezulu kwendlela enye yesandi kwaye enye eyaguqulwa ihlala ikhululekile okanye isibini. Umguquli ukhetha indlela enye yesandi ngokuzenzekelayo, ihlala iphambili, kwaye eli phepha alinakho ukumisela ukukhetha indlela eyahlukileyo. Ukuba enye engalunganga iphuma, yenza i WebM iphinde iguqulwe ngendlela oyifunayo kuqala (i-VLC okanye i-ffmpeg ingakwenza oku) kwaye uyiguqule kwakhona.

WebM

I-WebM yenzelwe iwebhu, inikezela ngokusasazwa kwevidiyo ngaphandle kwemali yokuhlawula ngeekhowudi zeVP8/VP9.

AMR

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