Yeah, uye zvinokosha kutarisira. Mafomati maviri ari kushaya, saka encoder AMR ari kushanda kubva kune audio iyo yaive yapfuura neimwe psychoacoustic pass, uye pfungwa dzayo dzinoumba yekutanga seti. Pa 192 kbps kana kupfuura, iyo mhinduro ichiri yakajeka kune vazhinji vanonzwa. Kana iwe uine master isina kushaya chero kupi, encoding the AMR kubva kune iyo inodzivirira double pass zvakakwana. MOV zvinonyanya kutakura H.264 kana HEVC kutumira, kana ProRes kana iri kushandura master, pamwe chete AAC kana PCM uncompressed audio. AMR i narrowband speech codec ichiita pakati pe4.75 ne12.2 kbps, ichifananidza munhu wechivanhu nechivanhu, asi kwete nezvose zvinotaurwa nezvokutaura.

Chii zvachose chinodarika kuparadzanisa chigaro chinoiswa chiri kubuda kana ichiitika. AMR inoravira ndangariro: 8 kHz bandwidth yake inoravira zvese zviri pamusoro pefoni frequencies, uye hapana mari yekudzokorora-kunyora zvinozoidzosera.

Nei mutauro wemutauro unonzwa sewevakadzi munguva iyi?

Nekuti imwe nzvimbo yacho inonzi codec yechitaura kupfuura codec yechirongwa chemuvhi. Inoratidza pfungwa dzevanhu uye inobvisa zvese zviri kunze kwebandwidth yefoni, izvo zvinokosha kana uchida kutumira meseji uye zvinokuvadza kana uchida kutumira chero chinhu chine mainstruments.

Nhamba dzezvinyorwa dzinoratidzwa mukuona kwekutumira kuti urege kusarudza zvakaipa.

Ndeipi bitrate iyo faira AMR inoshandisa?

Zviri pachena kuti bitrate yeAMR i 192 kbps (inoratidzika zvakanaka kune vamwe vanhu). Dzvanya pa 320 kbps kana uchida kuburitsa zvemabhaisikopo, kana 96-128 kbps kana uchida kuburitsa zvemabhaisikopo/podcast. Zviri pachena kuti faira rakakura rine kukosha kukuru.

Iine AMR yakabuda ichiita MOV sampling rate?

Zviri pachena kuti hapana — 48 kHz MOV audio ichange 48 kHz AMR audio, 44.1 kHz ichange 44.1 kHz. Kana iwe uchida kushambadza pasi kuti zvive zvakaenzana (e. g. 96 kHz studio masters to 44.1 kHz CD-quality AMR) iyo sample-rate dropdown inoita izvi nemhando yepamusoro yekushambadza.

Ndinogona here kubvisa AMR audio kubva pafolda ye MOV mafaera?
